Need Clarification on the casting in Java

Here's the question,

class {Alien
String invade (short ships) {return 'a little' ;}}
Invade the string (... brief ships) {return 'a lot' ;}}
}
{Defender class
Public Shared Sub main (String [] args) {}
System.out.println (new Alien (.invade) (7));
}
}

The answer is the compilation fails because the 7 argument must be cast for short.

Now my doubt is that more short is 16 bits in Java, 7 can be stored in a variable short, why do we need to cast?
If someone can clarify it?

5.3 reading here:

http://Java.Sun.com/docs/books/JLS/second_edition/HTML/conversions.doc.html

The above explains why the narrowing conversions do not apply when choosing a method to call (from possible overloads).
What they don't say is why they do not have an exception for the literal arguments, like 7.
I guess that's for simplicity and consistency.

  • Need clarification on the ANSI joins

    Hi all

    I need some clarification on the ANSI join I am building to avoid an error when I try to run the same in standard join.

    With standard join, I get the error ORA-01417: a table can be external joined as another table.

    Regular join condition:
    Select null

    You mix ANSI joins and the old joints. It's very confusing. Use all of one type or the other.
    >

    I want to know if the ANSI join is goig work properly or it will give me any Cartesian production information.

    What happens when try you it? Is it produces the results you want?

    Whenever you have any questions, post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data. Explain how you get these results from these data.
    Always tell what version of oracle you are using.
    See the FAQ forum {message identifier: = 9360002}

    Why the SELECT clause includes only NULL? Is that going to serve as an EXISTS subquery? If so, why bother to make the outer joins, and why do you care if it is a Cartesian product? What is the query to go for?
    For the purposes of debugging, you can include something that you see in the SELECT clause.

  • Need clarification on the explanation of size on a DVD

    Hi all

    I did a certain DVD so far with yet. Some are as short as 1 hour, some are as long as 2.5 hours. I continue to expect again to say "too video for the project"... but is not. I look at the menu "Generate" and he always says the same thing in 'disc info '.

    Here is a screenshot:

    Screen shot 2011-11-22 at 6.37.42 PM.png

    This project is of 2 hours 25 minutes. Is still somehow force on this 4 GB drive? Does this mean that certain quality will degrade? I bought a double disc burner layer thinking that soon I have to use it but so far I have burned projects that are big enough on my single layer.  Yet tell me when the project is too large for single layer?  Here is my system info:

    System: Mac OS X, version 10.6.8

    2.66 GHz Unknown processor

    Total physical memory: 8 GB

    Adobe still serial number: 976xxx

    Product version: 5.0.0.508

    First Media layer Version: -.

    Devices Blu - ray installed:

    None

    Installed DVD features:

    HL-DT-ST DVD - RW GA11N (Firmware KA19)

    Thank you guys!

    The answer will vary according to which challenge the material is (much higher than motion natures/low datarates needs movement), and the importance of quality is in your project.

    A rule of thumb is 2 hours is OK for a single layer, but some time at higher quality projects will be max on a disc single layer.

    And Yes, your 2 hours the project will be compressed to a high data rate (best quality) if still has two layers.

  • Need help with the coding of java base

    Hi I am new to java, please help me!

    Here the topic requires:

    circle2S.png

    • display the result of c1.contain (3.3)
    • C1. Contains (new Circle2D (4, 5, 8.5))
    • C1. Overlaps (new Circle2D (3, 5, 0.3))

    Here's my question:

    the circle contains must have (x, y, and radius)

    Why the contain (3.3) still work when there is no RADIUS?

    My code is correct?

    It's my circle2D code:

    public class Circle2D {}

    The center of the circle

    Private double x;

    Private double y;

    The RADIUS

    RADIUS double private;

    Constructor without parameters

    public Circle2D() {}

    This (0, 0, 3);

    }

    Constructor with x, y, and radius

    public Circle2D (double x, double y, double radius) {}

    This.x = x;

    This.y = y;

    This.RADIUS = RADIUS;

    }

    Get the zone method

    {} public double getArea()

    Return Math.PI * RADIUS * RADIUS;

    }

    Get the perimeter

    {} public double getPerimeter()

    return 2 * Math.PI * RADIUS;

    }

    Check if the point (X, Y) is in the circle

    public boolean contains (double X, double Y) {}

    If (Math.sqrt ((x-X) * (x - X) + (y - Y) * (y - Y)) < radius) {}

    Returns true;

    } else {}

    Returns false;

    }

    }

    Check if the new circle is the circle

    public boolean contains {(Circle2D circle)

    If (Math.sqrt ((x-circle.x) * (x - circle.x) + (y - circle.y) * (y - circle.y)) + circle.radius < radius) {}

    Returns true;

    } else {}

    Returns false;

    }

    }

    Check if the new circle overlaps the circle

    public boolean overlaps (circle Circle2D) {}

    If (Math.sqrt ((x-circle.x) * (x - circle.x) + (y - circle.y) * (y - circle.y)) + circle.radius > RADIUS)

    (& & Math.sqrt ((x-circle.x) * (x - circle.x) + (y - circle.y) * (y - circle.y)) + circle.radius < RADIUS + circle.radius) {}

    Returns true;

    } else {}

    Returns false;

    }

    }

    public static main (String [] args) {} Sub

    Circle2D c1 = new Circle2D (2, 2, 5.5);

    System.out.println (C1. Contains (3.3));

    }

    }

    I think you're confused by the abstraction.

    C1 is a Circle, a figure of dimension 2 covering an area. That's why he needs a RADIUS.

    The contains(x,y) of the method in the class circle valid a Point which is a figure without any Dimension. That is why the method does not have a RADIUS.

  • Need clarification for the code below:

    For your refernec, I am attaching the link too
    URL: Re: Interactive_Report with the search only bar



    Thank you
    David...

    David,

    Two things. First, it makes it much easier if you put '{code}' (without quotes) around your SQL when you publish:

    SELECT rowid "EDIT", attr_code,ATTR_ATCL_CODE "Atcl Code", attr_description, attr_atcl_code,
                attr_abbreviation,
                attr_include_short_desc "Include short desc",
                attr_include_long_desc "Include long desc",
                attr_attr_type "AttrType", rowid "DELETE"
           FROM t_new WHERE EXISTS (SELECT 1 FROM APEX_APPLICATION_PAGE_IR_COND WHERE APPLICATION_ID = :APP_ID AND PAGE_ID = :APP_PAGE_ID AND CONDITION_ENABLED = 'Yes'
AND APPLICATION_USER = :APP_USER) ORDER BY attr_description;

    If the spacing still needs work, it is a little easier to read.

    Second, your query exists clause checks just a State on, without checking the condition type. Without checking, I guess either APEX creates at least an inner State, or that your IR has a default condition on it (other than a filter). Try to add the constraint condition_type to your where clause to see if that solves it.

    Also, I noticed that you don't have additional code to get the report_id. It should not be necessary, because there are currently only supported for an IR by page, but you asked what are the differences.

  • Need clarification on the calculation IF statement script

    Hello guys,.


    Usually in my other projects, I used IF statement while writing scripts of calculation by mentioning some members in the LHS and assigning certain values to this member on the RIGHT side. But rrecently in one of my projects, I came with a new typical script which involves the IF function.

    Please find the script calc which is present in the system already below. Inviting you to give some idea on what it executes.

    Consider that I have seven Dimensions called account, Time_Period, JOBS, management, Source, Centre, matrix.

    DIFFICULTY ("no job, Apr)

    Fix (@UDA ("Account", "allowance"))

    DIFFICULTY (@RELATIVE ('A domestic', 0), @RELATIVE("Source A",0), @LEVMBRS("Centre A",0))

    SET CREATENONMISSINGBLK

    "Ratio" of the size of the matrix

    (

    IF ("BegBalance->" no branch "->" no Centre "->" input "of the size of the matrix == 1")

    'Ratio'->' value Allocated ' account dimension;

    ELSEIF ("BegBalance"-> "no branch"-> "No Centre"->"Input" == 2)

    'Ratio'->'value UnAllocate' account dimension;

    ELSEIF ("BegBalance"-> "no branch"-> "no Center"-> "Input" == 5)

    'Ratio'->'value Midalloc' account dimension;

    ENDIF;

    ON THE OTHER

    #Missing;

    ENDIF;

    )

    Here in the above script, after the condition of the IF statement, they did not mention any LHS = 'Ratio'-> "value Allocated"; but directly affected 'Ratio '->' value Allocated '... This means it applies to anywhere in the cube?

    Please explain.

    It is attributed to "Ratio", because it is the Member that you opened a calco block for with:

    "Ratio" (...)

  • Manager add-on said Java needs update, but the last Version already installed

    I have Java version SE7 U51 10.51.2.13 installed and works very well. Today, I 'upgraded' to 28.0 FF. Now Manager modules says Java is out of date, but when I go to the Java website, this is the latest version available.

  • Need a Clarification on the installed component and run Simulator Configuration

    Help!

    I need clarification on what the plugin Eclipse is telling me. There are two parameters that are confusing me. For components installed (found under preferences/Window/BlackBerry JDE/Installed Components), I have a choice of 5.0.0 4.7.0,4.6.1, 4.6.0 4.5.0 and 4.3.0.

    Depending on which component I select when I go in the tab Configurations.../Simulator/course walk, I see a different mix of devices.  In all cases, there is a default Simulator.

    Initially, I assumed that each JDE component supports a mixture of different devices, and that is it compiled correctly, I would be assured that the app would work for all devices on the tab run Simulator Configuration.  In my tests, I found theopposite.  I also assume that, for each component of the JDE, there is a 'default' Simulator that was representative of all devices in the drop-down list run Configuration Simulator.  In my tests, am not sure what actually represents the Simulator 'by default'.

    Can someone clarify how to JDE and Configuration simulators run installed interact and a developer show how to ensure that their application is running on a mix of devices?

    When I finally get to the point where I am ready to deliver, what are the points of decision of installation?  Is it enough to simply require a specific version of an operating system (for example 4.7?) or do I have to create a grid and check the two model number and version of the operating system?

    Thanks for your help.

    DCIteratorBinding dcLogs = (DCIteratorBinding) getBindings () .get ("LogTypesVO1Iterator");

    ViewObject voLogs = dcLogs.getViewObject ();

    List of JUCtrlListBinding = (JUCtrlListBinding) getBindings () .get ("LogTypesVO1");

    System.out.println ("LIST LOGS" + list);

    DCIteratorBinding iter = list.getDCIteratorBinding ();

    System.out.println ("ITER LOGS" + iter);

    RowSetIterator rsi = voLogs.createRowSetIterator (null);

    System.out.println ("RSI" + rsi);

    int i = 0;

    rowCount int = (int) voLogs.getEstimatedRowCount ();

    stateIndex = new int [rowCount];

    While (rsi.hasNext ()) {}

    System.out.println ("SEGUINTE!");

    Line nextRow = rsi.next ();

    iter.setCurrentRowWithKey (nextRow.getKey () .toStringFormat (true));

    INDX int = iter.getCurrentRowIndexInRange ();

    stateIndex [i] = indx;

    System.out.println ("INDEX" + stateIndex);

    list.setSelectedIndices (stateIndex);

    System.out.println ("LISTA" + list);

    }

    Then I valuechangelister to selectmanycheckbox this function:

    {} public void filterLogs (ValueChangeEvent valueChangeEvent)

    Dc2 DCIteratorBinding = (DCIteratorBinding) evaluteEL ("#{bindings.") EntityLogsVO1Iterator}");

    ViewObject vo2 = dc2.getViewObject ();

    String WhereClause = "LOG_TYPE in (";"."

    System.out.println ("VALUE" + valueChangeEvent.getNewValue ());

    If (valueChangeEvent.getNewValue ()! = null) {}

    java.util.ArrayList selectedValues = (java.util.ArrayList) valueChangeEvent.getNewValue ();

    for (int i = 0; i < selectedValues.size (); i ++) {}

    If (!.) WhereClause.equals ("LOG_TYPE in (""))

    WhereClause += ', ';

    WhereClause += "'" + selectedValues.get (i) + "'";

    }

    WhereClause += ') ";

    VO2.setWhereClause (WhereClause);

    VO2. ExecuteQuery();

    } else {}

    WhereClause = "1 = 2";

    VO2.setWhereClause (WhereClause);

    VO2. ExecuteQuery();

    }

    }

    But when I uncheck a selectmanychoice point, cause this error:

    valueChangeListener = "#{backingBeanScope.backing_OrderDetail.filterLogs}": java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast in java.util.ArrayList.] "

    My selectmanycheckbox have this property:

    < af:selectManyCheckbox value = "#{bindings." LogTypesVO1.inputValue}.

    label = "#{bindings." LogTypesVO1.label}"id ="smc1.

    Simple Binding = "#{backingBeanScope.backing_OrderDetail.SMC1}" = 'true' "

    layout = "horizontal" autoSubmit = 'true '.

    valueChangeListener = "#{backingBeanScope.backing_OrderDetail.filterLogs}" >

    < f: selectItems value = "#{bindings." LogTypesVO1.items}"id ="si2 ".

    Binding="#{backingBeanScope.backing_OrderDetail.si2}"/ >

    < / af:selectManyCheckbox >

    my version of jdev is 11.2.4.0

    You can not convert the ArrayList to direct object value

    java.util.ArrayList selectedValues = (java.util.ArrayList) valueChangeEvent.getNewValue ();

    write like this-

    ArrayList selectedValues = new ArrayList();

            Object [] str = (Object []) valueChangeEvent.getNewValue ();
            for (int i = 0; i)< str.length;="" i++)="" {="">
               

    System.out.println (STR [i]);

    selectedValues.add (str [i]); Add the values from an ArrayList
            }
