How to store values of TextField in table

Hello

I am trying to write a code to store values of TextField in a table. I know how to convert entire TextField. But after that, we have different integer variables. I can't understand how to store values of these whole different variables in a table by using a loop.

public class ArrAvg {}

Public Shared Sub main (String [] args) {}

int arr [10] = new int [10];

inputNumbers (arr);

}

void int inputNumbers (int arr [10]) {}

int i;

TextField field1 = new JTextField();

TextField Field2 = new JTextField();

Field3 TextField = new JTextField();

String value1 = field1.getText ();

String value2 = field2.getText ();

String value3 = field3.getText ();

val1 = Integer.parseInt (value1);

val2 = Integer.parseInt (value2);

val3 = Integer.parseInt (value3);

for (i = 0; i < 10; ++ I) {}

arr [i] = val1 (this should be replaced by val2 and after that by val3? I don't know how to do this)

}

}

Some body please guide me.

I have stored text field in ArrayList so i should traverse the ArrayList. But when i am converting the contents of Arraylist into integer, i am getting type mismatch despite the fact that my ArrayList is of String type.


Yes - the ArrayList to string but you create an iterator for object

Iterator itr = al.iterator (); getting iterator of arraylist to iterate through the items

This method of "al.iterator" () returns the iterator; for your use case E-online String. See the API

https://docs.Oracle.com/javase/8/docs/API/Java/util/ArrayList.html

You set it to 'Iterator' which is NOT a generic, so only objects are returned.

So get back to string.

Create your instance of the iterator Iterator.

Is it possible to avoid "iterator"?

Why avoid it? Just use the appropriate iterator.

The class has a 'size' and a method 'get (int index) '. So you can use a loop from zero to the 'size', but simply use the iterator.

    You cannot remove a single element of the VARRAY as the nested table. You can delete whole items or fine trim the VARRAY as below

    Nam. DELETE; ---> It will delete any element of VARRAY

    Nam. TRIM (1); ---> He will cut one of end of the varray--> nam. Trim (2)---> Trim 2 items

    Well you do almost everything bad that could be hurt.

    Here is the code that works to insert data into your table (the procedure is not even necessary).

    declare
    p_sl_num NUMBER := 1001;
    p_description VARCHAR2(50) := 'Testing Val1';
    inval1 test_type1 := test_type1();

    See example 5-15 making reference to an element of nested Table Chapter 5 using PL/SQL collections and records in the PL/SQL doc
    http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/Collections.htm#CJABEBEA

    1. you don't even have the procedure because it is a simple INSERTION in the table you can do directly (see my above code)

    inval1(1).val1 := 'testx1';
    

    Since you have not yet created all the elements, there is no element 1 "inval1". You need EXTEND the collection to add an element

    inval1.extend();
    

    And then, there is an empty element, but "inval1" is a container for objects of type 'test_object1' not for scalars as "val1", "val2", and "val3".
    If you can not do

    inval1(1).val1 := 'testx1';
    

    You must create an instance of 'test_object1 '.

    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    

    And so on for the other collection

    You don't need the procedure (as my code example shows), but once you fill in the variables correctly it will work.

  • JMS persist Store: how to store the messages in a table?

    Hi all

    I'm looking to create a composite that stores messages to a JMS queue on a custom table created. Please advise if the following approach is correct.

    1 has created a table within the dev soainfra: TEST_TABLE
    2 created a wls data source to point to the table: TestDS
    3. has created a persistent store based on above data source: TestStore
    4. has created a server with TestStore JMS in the persistent store: TestServer
    5 has created a JMS Module and the queue to the breast (* TestMod * & jms/TestQueue) it addressed to the TestServer.

    I created a JMS in my composite adapter configured to use my queue jms/TestQueue. The JNDI name used for the JMS adapter is the environmental assessment environmental/wls/queue.

    I ran a test and see nothing in my table. Is there something that I missed?

    JDev version: 11.1.1.4

    Thank you and best regards.

    in response to

    Also, how you consume messages from this table when the data is to the LONG RAW format?

    You do not have. It is an integral part of WLS JMS. You consume messages using a JMS consumer, whether another instance of the adapter or another java client. If you start deleting messages from this table manually, you will mess up JMS and cause of exceptions. I suggest you leave well alone.

  • How to store data points in the table

    I'm new to labview and I am trying to store the output of the frequency of 'measures pulsed VI' in a table, add everything together and divide by the length of the array. I don't want a table of numbers to be shown on the indicator. Just average 25 numbers.

    Basically, I want to do, but in labview.

    arrayIndex = 0;

    for (int i = 0; i)<=25;>

    {

    NewData = somedata;

    MyArray [arrayIndex] = newdata;

    dataAvg = dataAvg + myArray [arrayIndex];

    arrayIndex ++;

    }

    dataAvg = dataAvg / 25;

    I have attached my attempt, but its probably a very poor attempt. (The N on my first loop for was 25 when I tried to run the VI)

    Thanks in advance

    You need n number of bed DAQmx to take the average of the number n of steps of the pulse. Silly to take 500 what whatsoever when you have a single DAQmx reading which returns a single measure. As I said, you can use a registry to offset or point-by-point inside the loop. Or, run a number n of the acquisition of times with a loop and moves the pulse measurement in the table for automatic indexing and calculate an average, when all acquisitions are made.

    Hello

    Past_Due and Task_Count are calculated fields and are therefore useless.
    You must not store redundant data (in general).
    Your past_due also uses a reference to sysdate, so the value is today different from tomorrow. You expect the database to change the value from one day to the next?
    So keep the data where it is and display calculated to your users using your query fields (oher options are available, but you already have the request I will not go in the).

    Hello

    I have a FORM on a table with two or three elements. How to assign values to the elements of the application with the values in the elements of form, every time the value of the element is entry, change or page is sent?

    I created a dynamic action to the region level with Event - change to run the suite of PL/SQL, I tried with 3 different ways in PL/SQL, as shown below, but it didn't work.

    BEGIN

    : APP_FY: =: P1_FY;

    APEX_UTIL. SET_SESSION_STATE ('APP_FY', v: P1_FY);

    END;

    Then I created an action dynamic at the ITEM level with change event to run the suite of PL/SQL and tried with PL/SQL, as shown below, but it didn't work.

    I need to assign values to the elements of the request form as these elements of the application will be used in many other pages in the application. How to I get there?

    Thank you.

    If a dynamic action of PL/SQL execution, you must send your list of page elements in the parameter "Elements of Page to submit.

    See the section 'run pl/sql' for this post.

    If the page is submitted, the elements of the page will be automatically set to session state, and you can have a page process make the code you have.

  • How to get the value of an af:Table SelectOneChoice

    V11.1.2.4.0 - JSF JDeveloper

    Greetings,

    Im having a problem getting a column value that is an object of a select choice.

    This isn't a common problem, as I actually did something that others so please follow my problem

    Description and if you have questions/answers please answer below.

    I create a database view that returns me 3 columns, say TestValue TestCode, TestDescription.

    I added an extra temporally column in my OV and called Temp.

    I drag / drop my OV, remove value Temp and its position of the column, I drag / drop a LOV, who comes from a different view.

    that shows me the doctor name & first name and identification number of the back doctor select a value of choice.

    I'm using a function that go through the iterator, gets the lines and save them in the database (no matter how).

    The problem is my selectonechoice, are not row.bindings.DoctorId.InputValue, but the links. DoctorId.InputValue instead, so I can retrieve value selectonechoice of the current line.

    Then when my loop is finished and insert rows in my database, id of the doctor of the line everyone is the same as the binding do not change through the loop.

    I don't know how to add value to the current line select only one option to use the correct value to each loop of the line.

    Here is my loop function:

            DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
            DCIteratorBinding iterator = bc.findIteratorBinding("ExaminationsIterator");

    I get the connection id of the current doctor and the value of the rows no.

    Can you help me on this please?

    I created a work around solution, until an expert that I come with a more advanced solution.

    (1) I add a LOV at the id of the doctor on the view target object.

    (2) on the duration, I fill my view of database

    3) go through all my DB view iterator lines

    (4) appends each line on the View object target (missing id of the doctor, because I want it to be on common language runtime) & commit lines

    (5) after the loop ends and the target object from view show me results from the view of DB, I choose the runtime id of the doctor and commit the changes if

    the new lines, with the new update will be finally filled to the database.

    I hope this helps if anyone has a similar task.

    Please let me know if you find a more direct solution, this work with 2 tables to fill 1.
