Add key/value pairs to an ArrayList from a HashMap in

I'm trying to create a HashMap, loop through this hash table, and finally, I try to create an ArrayList of key/value - of the HashMap pairs - containing, in its set of value, a parameter value. I know that maybe it's a little difficult to understand, so I provided my code to make sense what I'm trying to accomplish.
package data;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

public class ProductInventory 
{  
    private Map <String, ArrayList<String>> product;
    private ArrayList <String> buildProduct;
    private ArrayList <ArrayList<String>> addProduct;

    public ProductInventory()
    {   
        /** Set default values **/

        product = new <String, ArrayList<String>> HashMap();
        buildProduct = new ArrayList<String> ();
        addProduct = new ArrayList<ArrayList <String>> ();
        
        /** START - Create ArrayList for each item and add to HashMap**/

        ArrayList <String> c1 = new ArrayList<String>();
        ArrayList <String> c2 = new ArrayList<String>();

        c1.add("computer"); c1.add("Apple"); c1.add("iPad2"); c1.add("499.00");
        c2.add("computer"); c2.add("Asus"); c2.add("Zenbook"); c2.add("1449.00");

        ArrayList <String> tv1 = new ArrayList<String>();
        ArrayList <String> tv2 = new ArrayList<String>();

        tv1.add("television"); tv1.add("Panasonic"); tv1.add("Viera"); tv1.add("899.00");
        tv2.add("television"); tv2.add("Samsung"); tv2.add("Series 6"); tv2.add("1597.00");

        ArrayList <String> a1  = new ArrayList<String>();
        ArrayList <String> a2 = new ArrayList<String>();

        a1.add("audio"); a1.add("Bose"); a1.add("321 GS Series III"); a1.add("999.00");
        a2.add("audio"); a2.add("Onkyo"); a2.add("HT-S3400"); a2.add("329.00"); 

        /** END - Create ArrayList for each item and add to HashMap **/

        /** Add entrys to HashMap **/

        product.put("CMC769LLA",c1);
        product.put("CUX31EDH72",c2);
        product.put("TVTCL50E3",tv1);
        product.put("TVUN55D6000",tv2);
        product.put("A321GSIIIBK",a1);
        product.put("AHTS3400",a2);

    }

    /** For the sake of this example, the productAttribute parameter will be equal to "computer"  **/
    
    public void setProducts(String productAttribute)
    {
            for (Map.Entry <String, ArrayList<String>> entry : product.entrySet()) /** Loop through all entrys in the HashMap **/
            {              
                for (String s: entry.getValue()) /** Loop through all values in HashMap**/
                {
                    /** Add product attributes **/
                    if (s.equals(productAttribute))  /** Check to see if param exists in the value set**/
                    {
                       /** Add key to buildProduct ArrayList **/
                        buildProduct.add(entry.getKey()); 

                         /*Loop through values of the corresponding key and add to buildProduct*/
                        for (Iterator<String> i = entry.getValue().iterator(); i.hasNext();)
                        {    
                                Object item = i.next(); 
                                buildProduct.add(item.toString());
                        }
                        
                        /** Add buildProduct arrayList to product arrayList **/
                        addProduct.add(buildProduct);
                        break; /** Exit nested loop**/
                    }
                }
            }  
    }
}
For the desired output, it can be assumed that the value of the productAttribute parameter is "computer."

Output current of the ArrayList addProduct:
Size of ArrayList: [2]
Content of each element:
[0] - (Size [10]
      [0] - "CMC769LLA"
      [1] - "Computer"
      [2] - "Apple"
      [3] - "iPad2"
      [4] - "499.00"
      [5] - "CUX31EDH72"
      [6] - "Computer"
      [7] - "Asus"
      [8] - "Zenbook"
      [9] - "1449.00"
[1] - (Size [10])
     /**  It includes the exact same content as element [0] **/
Desired output of the ArrayList addProduct:
Size of ArrayList: [2]
Content of each element:
[0] - (Size [5])
      [0] - "CMC769LLA"
      [1] - "Computer"
      [2] - "Apple"

      [1] - "Computer"
      [2] - "Asus"
      [3] - "Zenbook"
      [4] - "1449.00"
I can't understand what I'm doing wrong. Any help would be greatly appreciated.

You have defined buildProduct and then add to it.

buildProduct = new ArrayList ();

Do this assignment at the top of each loop so that a new ArrayList is allocated.

1 buildProduct = new ArrayList () ;
2. Add your 4 things using buildProduct.add
3. Add buildProduct to your 'mother' object - addProduct.add (buildProduct);
4. loop back to step 1 and create a new arraylist to the next set of elements

  • How to programmatically Exchange data (key-value pairs) with operating system called?

    Hi all

    Is there a programmatic way to Exchange data (of the key-value pairs) with the guest OS?

    We have an application that runs inside comments, and we want that this application in order to use this mechanism to Exchange data. At this point, the guest have no network connectivity. One thing that might work for us is to use the registry to the guest operating system. But I'm not sure how to handle the registry of the guest operating system.

    We looked in the VirtualMachineConfigInfo.extraConfig property, but these key-value pairs are not accessible from the comments (at least this is what I know)

    any ideas?

    Thank you

    Onur

    I think that it is better to use an environment variable or file to Exchange data with the guest operating system.

    I'm looking to invoke the application Remember and I try to send a title and a due date. The problem is that I don't know the format for sending multiple data items. Can someone help me with the format what should I use to having an remember entry created with a title and a due date?

  • What is the best way to move with esx3.5 vmtools key/value pairs?

    Hello

    I found both candidates to store the key/value pairs for a vmware client. My ultimate goal is to run a process on the VC box that updates these data, and then read through the software tools of vm on the host (somehow) were invited.

    The first method is through 'guestinfo' settings which can be adjusted in four ways:

    Add the variable of the vmx fileprompt.
    Set the variable manually on the client (using vmwareservice.exe - cmd "infoset");
    using vmware-cmd (vmware-cmd & lt; vm-cfg-path & gt; setguestinfo & lt; variable & gt; & lt; value & gt;)
    the use of vmcom.dll COM objects (seems to be deprecated in ESX 3.5)
    These variables are easily accessible on the client by running vmwareservice.exe - cmd 'info-get guestinfo.variablename '. However, I cannot find a convenient way (better based on powershell) of their definition of a scheduled task or service to VC area.

    The second method is the customfields of guests in VItoolkit property, which can be defined as follows:

    get - vm MyVMName | Game-CustomField-nameOfValue name-value DataToBeStored
    Unfortunately, I am unable to access these data in the comments, and indeed I do not know if this is possible. If this isn't the case, I guess my only recourse would be to write a tool to connect to Web services on the VC box with a low privilege account. I prefer not to do this because it means the network infrastructure implementation to point the guest to the right VC, development of custom etc permissions...

    So, my questions are:

    • Is it possible to define variables of guestinfo through VI Toolbox, running on the virtual circuit?

    • Is it possible to read customfields on the client, through the vmtools?

    • Or is there another method to make this key/value data exchange?

    You can add/edit entries in the VMX file like this

    $vm = get-vm  | Get-View
    
    $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
    $vmConfigSpec.extraconfig += New-Object VMware.Vim.optionvalue
    $vmConfigSpec.extraconfig[0].Key= "guestinfo"
    $vmConfigSpec.extraconfig[0].Value = "whatever"
    
    $vm.ReconfigVM($vmConfigSpec)
    
  • To access the inside loops key/value pairs

    According to the docs of Shopify, liquid allows access to key/value pairs in for loops, as follows:

    {% for item in hash %}   {{point [0]}}: {{point [1]}} {% endfor %}

    This does not work in the liquid renderer in British Colombia; the output of the key/value tags are empty. Here is an example of using the always available this.urlculture global object:

    {   ...   {"urlculture": {"ModuleName": "urlculture", "culture": "EN"},...}

    {% for obj in this.urlculture %}

    {{ obj | json }}
    Key: {{obj [0]}}
    Value: {{obj [1]}}
    {% endfor %}

    This is the result I get:

    {
      "Key": "moduleName",
      "Value": "urlculture"
    }
    
    Key:
    Value:
    
    {
      "Key": "culture",
      "Value": "EN"
    }
    
    Key:
    Value: 

    Access by name (such as {{ obj.Key }} ) also fails.

    Am I missing something, or is this all just not yet implemented?

    Also, why isn't the nice formatting illustrated in this visible post editor in the current post code?

    Thank you, Robert.

    This was a great find. And you'll be happy to learn that we have set and it will work in the next version (unfortunately the hotfix does not update today, we have deployed on the beta version).

    You will then be able to do things like:

    {% for getParam in globals.get %}
    {{getParam[0]}} = '{{getParam[1]}}'
    {% endfor %}

  • Need help to build the query/pl-sql block to get the query result and the name of column from DB table in the form of key-value pairs.

    Hi Experts,

    I have a DB table has columns of more than 50.

    I question this table, it should only return one line at any time. as sqldeveloper below image.

    here, I need to build block pl/sql-query, Discover the column in the table as a key and query result as values.

  • Key value pair relational table - cross tab / pivot out?

    I have a Table of KVP and the structure is ID, Key, Value and this is the sample values...

    Table with values

    ID, Key, Value
    TABLE 1, TRUE
    1, AGE GROUP, 10
    1, TRAVEL, Y
    2, TABLE, FALSE
    2, AGE GROUP, 20
    2, TRAVEL, N

    I want to turn it these date like below (output)

    ID, STATUS, AGE GROUP, TRAVEL
    1, TRUE, 10, Y
    2, FALSE, 20 N

    I read on analysis crossroads/pivot - but not able to make a query that can give me the output above. The structure of the table cannot be changed...! My bad.

    Is it possible in sql, to do my output to look like above?

    It is possible if you know all the possible values for the KEY:

    with t as (
               select 1 id,'STATUS' key,'TRUE' val from dual union all
               select 1,'AGE GROUP','10' from dual union all
               select 1,'TRAVEL','Y' from dual union all
               select 2,'STATUS','FALSE' from dual union all
               select 2,'AGE GROUP','20' from dual union all
               select 2,'TRAVEL','N' from dual
              )
    select  id,
            max(case key when 'STATUS' then val end) status,
            max(case key when 'AGE' then val end) age,
            max(case key when 'AGE GROUP' then val end) "AGE GROUP",
            max(case key when 'TRAVEL' then val end) travel
      from  t
      group by id
    /
    
            ID STATUS AGE   AGE GROUP TRAVEL
    ---------- ------ ----- --------- ------
             1 TRUE         10        Y
             2 FALSE        20        N
    
    SQL> 
    

    If you are on 11g, you can use the PIVOT, but again, he must know the columns resulting from the outset.

    Another thing, you could do is to return a list CSV key of all the values in a column using STRAGG (or LISTAGG if you are on 11.2), hierarchical queries, XML or WM_CONCAT without papers.

    Hello

    update to 2.1 MAF gives you , that can be added to HTML files the and remote access to the MAF since JavaScript API. Deepak mentioned "adf.mf.api.gotoFeature" and I can confirm it works HTML distance (and so it should be using local HTML). For the transmission of data, not sure whether the request URL object it. I would try here EL referencing a managed bean of application-scope defined in the scope of application (?). I tried beans controlled but so far has not tried to access the managed beans to a feature local or remote HTML using EL (although the EL is here)

  • How to read file(key-value) in OSB properties?

    Hello

    I have a scenario in which I have to read a few properties(key-value) in a file. Former entire code was developed in java and it is easy to read the java properties file.
    But now I need to implement this in OSB and performance is a crucial element in this project.

    I followed DVM approached defined in

    But it did not work. I have hundreds of properties (key-value pairs) to read and must transmit it to the service of the company and with the intervention of the proxy service.

    What is the best approach for this (can't go to db call performance being very critical)?

    Thank you

  • How to combine the large number of tables of pair key / value in a single table?

    I have a pair key / value tables of 250 + with the following features

    (1) keys are unique within a table but may or may not be unique in the set of tables
    (2) each table has about 2 million lines

    What is the best way to create a single table with all unique key-values of all these paintings? The following two queries work up to about 150 + tables
    with
      t1 as ( select 1 as key, 'a1' as val from dual union all
              select 2 as key, 'a1' as val from dual union all
              select 3 as key, 'a2' as val from dual )
    , t2 as ( select 2 as key, 'b1' as val from dual union all
              select 3 as key, 'b2' as val from dual union all
              select 4 as key, 'b3' as val from dual )
    , t3 as ( select 1 as key, 'c1' as val from dual union all
              select 3 as key, 'c1' as val from dual union all
              select 5 as key, 'c2' as val from dual )
    select coalesce(t1.key, t2.key, t3.key) as key
    ,      max(t1.val) as val1
    ,      max(t2.val) as val2
    ,      max(t3.val) as val3
    from t1
    full join t2 on ( t1.key = t2.key )
    full join t3 on ( t2.key = t3.key )
    group by coalesce(t1.key, t2.key, t3.key)
    /
    
    with
      master as ( select rownum as key from dual connect by level <= 5 )
    , t1 as ( select 1 as key, 'a1' as val from dual union all
              select 2 as key, 'a1' as val from dual union all
              select 3 as key, 'a2' as val from dual )
    , t2 as ( select 2 as key, 'b1' as val from dual union all
              select 3 as key, 'b2' as val from dual union all
              select 4 as key, 'b3' as val from dual )
    , t3 as ( select 1 as key, 'c1' as val from dual union all
              select 3 as key, 'c1' as val from dual union all
              select 5 as key, 'c2' as val from dual )
    select m.key as key
    ,      t1.val as val1
    ,      t2.val as val2
    ,      t3.val as val3
    from master m
    left join t1 on ( t1.key = m.key )
    left join t2 on ( t2.key = m.key )
    left join t3 on ( t3.key = m.key )
    /

    A couple of questions, then a possible solution.

    Why the hell you have 250 + tables pair key / value?

    Why the hell you want to group them in a table containing one row per key?

    You could do a pivot of all the tables, not part. something like:

    with
      t1 as ( select 1 as key, 'a1' as val from dual union all
              select 2 as key, 'a1' as val from dual union all
              select 3 as key, 'a2' as val from dual )

    If you can do it in a single query, Union all 250 + tables, you don't need to worry about chaining or migration. It may be necessary to do this in a few passes, depending on the resources available on your server. If so, I would be inclined to first create the table, with a larger than normal free percent, making the first game as a right inset and other pass or past as a merger.

    Another solution might be to use the approach above, but limit the range of keys with each pass. So pass we would have a like predicate when the key between 1 and 10 in every branch of the union, pass 2 would have key between 11 and 20, etc. In this way, everything would be straight inserts.

    That said, I'm going back to my second question above, why the hell you want or need to do that? What is the company you want to solve. There could be a much better way to meet the requirement.

  • Using XML as a pair key / value in OSB 11 g

    Hi all

    I made a new Test project. There are only 2 files:
    1 proxies - that contain proxy services
    2 xml - containing XMLs

    An example of XML (XML name - TestXML) present in the xml file:

    < valueDetails >
    ABC < key1 > < / key1 >
    < > 123 key2 < / key2 >
    a12s < key3 > < / key3 >
    < / valueDetails >

    I want to use in the pipeline of proxy as key-value property services. How do I get there?

    I use OSB 11 GR 1 material.

    Thanks in advance!

    Kind regards
    Karthik.

    Save the XML as a resource of xquery to the osb. Then, use an entitled action for load in the pipeline. For example affect XQuery resources KeyPairsXML to $keypairs. After this $keypairs will be your xml and appropriate xpath allows to recover the key you want,

  • Trigger - use one to create primary key values

    I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.

    I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.

    Here's what I have.

    CREATE TABLE HF_fishers

    (

    contact_id INT NOT NULL

    , name VARCHAR (25)

    , last_name VARCHAR (35)

    PRIMARY KEY (contact_id)

    );

    CREATE SEQUENCES HF_fishers_seq.

    Then I ran the following trigger:

    CREATE

    HF_fishers_seq_trigger RELAXATION

    BEFORE INSERTING

    ON HF_fishers

    FOR EACH LINE

    BEGIN

    IF (: new.contact_id IS NULL)

    THEN

    : NEW.contact_id: = NVL (: NEW.contact_id)

    HF_fishers_seq. NEXTVAL

    );

    END IF;

    END HF_fishers_seq_trigger;

    =============

    Then I executed the following SQL statement that gives the error.

    INSERT INTO HF_fishers VALUES('Jacob','Muller');

    But if I do everything is good except that it defeats the purpose of relaxation.

    INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');

    MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

    OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?

    -After the code trigger of Jaramillo

    INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.

    INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens");  -No trigger but get key duplicated,.

    INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.

    My mistake.  Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.

    So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine.  The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding.  Colon only works in a trigger without asking for confirmation.

    Here is the code and my exit I ran home

    DROP TABLE hf_fishers CASCADE CONSTRAINTS PURGE;
    DROP SEQUENCE hf_fishers_seq;
    
    CREATE TABLE hf_fishers
    (
    contact_id   INTEGER NOT NULL
    ,first_name   VARCHAR(25)
    ,last_name    VARCHAR(35)
    ,PRIMARY KEY (contact_id)
    );
    
    CREATE SEQUENCE hf_fishers_seq;
    
    CREATE OR REPLACE TRIGGER hf_fishers_seq_trigger
       BEFORE INSERT
       ON hf_fishers
       FOR EACH ROW
    BEGIN
    
       IF(:NEW.contact_id IS NULL) THEN
          :NEW.contact_id := hf_fishers_seq.NEXTVAL;
       END IF;
    
    END hf_fishers_seq_trigger;
    
    INSERT INTO hf_fishers(first_name, last_name)
         VALUES ('Jesse', 'Owens');  -- Works with the trigger
    
    INSERT INTO hf_fishers
         VALUES (hf_fishers_seq.nextval, 'Jesse', 'Owens');  --Works without using the trigger body code.
    
    SELECT *
      FROM hf_fishers;
    
    COMMIT;

  • With the help of several key values to find the data

    Hello, it's me again.

    I had a question out about data from database and display them on a page of the ADF on Jdev 11.1.1.3.

    And Mr. Daniel Atwood answered my question with this blog to follow, that wrote.
    http://www.avioconsulting.com/blog/datwood/2012/06/19/using-BPM-process-variable-ADF-form-retrieve-database-information-0.

    But I have another question on top that.

    The Mr.Atwood example is when using a value of key 'one', what happens if I have two key values, how to set?

    Here are some details:

    I have a table like this

    ID Type_code name
    0001 05 a-blabla
    0002 b 25-blabla
    0002 26 b-blabla
    0003-08 c-blabla
    0003 25 c-blabla
    0003 c 79-blabla

    What I want to do is after the entry of the ID (0003) and type_code (25), he will show me the result on three components of text entry in the ADF with the value 0003, 25 page and c-blabla.

    Currently, I use only ID to query the data, but I would use two key values to find specific data.

    Thank you very much for taking the time to think about it,

    Sincerely,

    Alto

    If you had multiple values to use for the request, one approach would be to create a display object. Whether you are creating the view object, in step 6, you will add two bind variables. Call a "pTypeCode" and call the other "pId". Click on the back button so that you're still in step 5, and modify the WHERE clause as follows:

    (ID = :pId) and (Type_code = :pTypeCode)
    

    After you have done this, double-click the Module of the Application and add your new view object. In the tab control of data, click the Refresh button. Expand your new view object tab of data control-> expand "French"-> note that you now have a new method called "ExecuteWithParams".

    Open your workflow diagram-> delete your existing "SetCurrentRowKeyValues" method-> made slide on your new "ExecuteWithParams" operation on the diagram. When you do so, you should see two settings you need to complete the dialog box. Just as you did before with the SetCurrentRowKeyValue method, set the values for the pTypeCode and the nest.

    Add the case of control flow of the new method to your existing view-> make the new method, the default value.

    On your form, remove the fields that have been placed here who uses the old object from view. On the tab of data control, drag the fields you want to be placed on the inside of your new view object form.

  • Add the value of point two apex and display the result in another part of the apex

    Hello

    I need to make the addition of the two item values using apex.item.text and find the result in another apex.item.text.

    For example:
    SELECT
    apex_item. Text(1,null) ONE
    apex_item. Text(2,null) TWO
    apex_item. Text(3,null) RESULT
    FROM EMP
    please suggest me

    Thank you
    Sudhir

    >
    No it does not add the two values in the column, user key to enter the value, it must add the value of the item and displays the result in a dynamic way. Need a suggestion for using javascript
    >
    This requirement was not not clear in the op.

    See the demo of Denes Kubicek.

    This topic is discussed far too often. Have you tried to Oracle Application Express (APEX) and adapting one of the many examples of LoV cascading to your situation?

    See you soon,.

    PS: Tip:
    Look for the p_item_id and p_attributes of the APEX_ITEM API parameters.
    You can call JS functions for example using p_attribute

    APEX_ITEM.TEXT(...
    p_attributes => 'onchange="doTotal(this);"', /* doTotal being your JS Function */
    ...

  • How to use Boolean as a constant push to add more values

    Hello everyone, I am trying to use a Boolean OK button and a constant to do something similar to the calculator project that I read in other posts. I scored $1.00, $0.25, button...  So now.  I just want to add the value of an indicator whenever I press the button.

    Is the closest I can get is displayed while I hold the button in and it goes to 0 as I realese it. I want that it add up every time his press.

    Thanks in advance

    Kevin

    Hi Kevin, this is Paul of engineering Applications at OR.  Try something like in my attachment.  You can use instructions of type of case to determine if a key has been pressed, and then assign this case real value.  Good luck with it
