Simple code to solve

WE HAVE
int name(int i);
void name(int i);
1. what will happen when running this code in same class.?
2. what will happen when running this code(one method in super class and other in subclass)?

Try it... it won't compile for the same class.It will only come close to compiling for an interface
(the methods have no body)your eyes are pretty sharp ;)

What's wrong with this simple code?

What's wrong with this simple code? Complier points out that
1. a '{' is expected at line6;
2. Statement expected at the line which PI is declared;
3. Type expected at "System.out.println("Demostrating PI");"
However, I can't figure out them. Please help. Thanks.
Here is the code:
import java.util.*;
public class DebugTwo3
// This class demonstrates some math methods
public static void main(String args[])
          public static final double PI = 3.14159;
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Change your code to this:
import java.util.*;
public class DebugTwo3
     public static final double PI = 3.14159;
     public static void main(String args[])
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

A simple problem to solve... I hope.

$A simple problem to solve... I hope. Hi Guys,
This is my first post on this forum, and I'm hoping that the problem I'm encountering at the moment is down to my own stupidity rather than technical issues.
Firstly, I should mention that I have used my X-fi sound blaster xtreme audio card for months now in my old PC which was running XP 32 bit with no problems whatsoever. In the last day I've built a new PC which has the following specs:
Intel I7 860
tb HDD
4gb Ram
Windows 7 Ultimate 64
Nvidia GTX280
Sound was very quiet and of a fairly poor quality to begin with, and I soon realised that I hadn't installed any drivers for the soundcard, so I went ahead and did so. Following this, I enter a **bleep**storm of illogical proportions which to me makes absolutely no sense.
I get no sound from my speakers or headphones whatsoever. I have a pair of M-Audio AV-40 monitors at the moment, and no matter what I try, I can't get sound to work. When I go to the mixer, it seems odd to me
http://yfrog.com/7fxfiproblemj
I thought that there would be options for Line Outs etc, but I may be wrong.
I've run the diagnostic tests and everything comes back absolutely fine.
The weirdest thing however is the fact that when I test the speaker configuration, it responds to nothing except from the 7. surround sound, and my speakers react to the bottom left and bottom right speakers. I've tried installing, re-installing drivers no end. Looked for fixes and checked google as well and found nothing that matches the description of my problem.
Am I missing out on something really obvious here? Or is there a more technical underlying factor ?behind this issue.
Any help is hugely appreciated, thanks?

Thanks for all of you help, but I still don't think the problem's solved.
Here's the problem explained more thouroloy. I have a java program that uses lots of jar files. That means that to run my program, I need to have the CLASSPATH set to pick up all of these jar files. I'd also like to be able to give someone a copy of this program on a cd and have them immediately run it without having to assume anything about their configuration (except that they have java installed).
So what I did was create a batch file that (at least temporarily) sets up the CLASSPATH to meet my needs. It then calls "java myProgram <all the other parms...>".
Things run fine, except that the command window that gets opened up stays around while Swing program runs, and doesn't close until I close the Swing program. I'd like that that didn't happen.
-- echo off
Not going to do anything to help. It will stop the batch commands from echoing, but that's about it.
-- javaw
I tried this and it also doesn't work. It seems that neither java nor javaw return until after the program that it is running actually end.
-- Executable jar
Sounds promising, but will it work? How do I make sure the CLASSPATH is properly set before running this?
Thanks again for all of your hlep.

Convert simple code from as2 to as3

Hello, i am looking for some help here for something simple (i think)
var txt:String = link1;
btn.onRelease = function():Void {
if( sample_id )
getURL("http://www.website.com/registration?partner_id=" + sample_id + "sampleURLCode", "_blank");
else
getURL("http://www.website.com/registration?sampleURLCode", "_blank");
Is there a way to make this simple code into AS3?

Hi, Apparantly that's because the 'link1' and 'sample_id' variables are not within the scope of the code you posted above, Perhaps you have defined them outside on a different frame or class. You can either define them with the same code like:
var sample_id:Number=1234; //Use your own variable type and value here
var link1:String = "your string or link URL here";
var txt:String = link1;
btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(e:MouseEvent)
if( sample_id )
      navigateToURL(new URLRequest("http://www.website.com/registration?sample_id=" + sample_id + "sampleURLCode"),"_blank");
else
      navigateToURL(new URLRequest("http://www.website.com/registration?sampleURLCode"),"_blank");
Or you can put a direct reference to your existing variable like (If your variables are defined on root/frame 1) :
var link1:String = "your string or link URL here";
var txt:String = MovieClip(this.root).link1;
btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(e:MouseEvent)
if( MovieClip(this.root).sample_id )
      navigateToURL(new URLRequest("http://www.website.com/registration?sample_id=" + sample_id + "sampleURLCode"),"_blank");
else
      navigateToURL(new URLRequest("http://www.website.com/registration?sampleURLCode"),"_blank");
try that, or you can share your .fla !

Anyone have Simple Code to Play an .Flv file on a Website?

Hi,
Can someone please tell me how to make a web page play a .flv file.
Simple, basic code would do.
I have an .flv file uploaded on my website.
How do I get the Flash Player to play the file when someone visits the page?
Again, all I'm looking for is simple code.
Thanks,
Joe

add an flvplayback component to your swf. give it an instance name (say flv). then use:
flv.contentPath="yourflv.flv"; // for as2
flv.source="yourflv.flv"; // for as3

Data Binding: Simple code does not work.

hi... the following simple code is used to display the ename field for a record selected in scott.emp on the console. the code is placed in an event handler. it is as follows:
DCBindingContainer bindings = ctx.getBindingContainer();
DCControlBinding binding = bindings.findCtrlBinding("ename");
String Name = (binding != null) ? binding.toString() : "";
System.out.println(Name);
is the code above correct????
if so, why it does not work???
thanks for every help in advance & best regards.

Hi,
please check the UIModel.xml file for the page if the binding name is "name". The code you have is the same code we published in our QBE workshop and it works there. The only difference is the name of the control binding. So please check if the binding name exists. (e.g. it could be ename1 instead of ename)

What's the simple code for this?

Hello, I know it is a very simple code but what is the code if I want to have different properties for headings and such in different id's. For example I want ID "sidebar"'s headings to be aligned in the center but I want ID "main-body"'s headings to be aligned to the left. How would I go about doing that?
Thanks!

CSS:
body {
text-align:left;
#sidebar h1,
#sidebar h2,
#sidebar h3,
#sidebar h4 {text-align:center}
/**re-usable classes**/
.center {text-align:center}
.right {text-align:right}
HTML:
<div id="main_body">
<h1>This is left aligned by default</h1>
<h2 class="right">This is right aligned by virtue of the class .right.</h2>
</div>

XML simple code help

That looks like Javascript to me. This forum is about Java and XML, not Javascript and XML. However the error is pretty obvious:
var msgNodes = doc.documentElement.getElementsByTagName('message');You don't have any elements named "message" in that XML document. You have an element named "message1" and an element named "message2" and an element named "message3", but no "message" elements. So you get a list of zero elements there. You need to rewrite your DOM-handling code to reflect the actual input.

How to sort a list of strings, without methods and stuff just simple code?

Hi
How to sort a list of strings, without methods and stuff just simple code?
Thanks in adavance!!

Without methods? How are you going to all the sort code? What is the point of code?
Collections.sort(List) will sort strings or anything that implements the Comparable interface, or you can use the sort method that takes a Comparator implemenation.
If you want "just code", you could either get the Collections class souce and follow it to the code. But otherwise, there isn't one set of code. There are various sorting algorithms with advantages and disadvantages. Maybe you'd be better off searching for sorting algorithms and if you understand them, it should be simple to write Java implementations of them.

Still having probs running simple code in SE8

I copied a very simple code into SE8 and compiled it. Please find folowing the code and the output:
package average2;
    import java.text.DecimalFormat;
    import java.swing.JOptionPane;
public class Main {
    public Main() {
    public static void main( String args[] )
            int total;          // sum of grades
            int gradeCounter;   // number of grades entered
            int grade;          // grade value
            double average;     // number with decimal point for average
            String gradeString; // grade typed by user
            // initialisation
            total = 0;          // initialise total
            gradeCounter = 0;   // initialise gradeCounter
            // processing phase
            // get first grade from user
            gradeString = JOptionPane.showInputDialogue( "Enter Student Grade or -1 to Quit:" );
            // convert gradeString to int
            grade = Integer.parseInt( gradeString );
            // loop until sentinal value is reached
            while ( grade != -1 ) {
                total = total + grade;          // add grade to tatal
            gradeCounter = gradeCounter + 1;    // increment counter
            // get next grade from user
            gradeString = JOptionPane.showInputDialogue( "Enter Student Grade or -1 to Quit:" );
            // convert gradeStrin to int
            grade = Integer.parseInt( gradeString );
        }   // end while
            // termination phase
            DecimalFormat twoDigits = new DecimalFormat( "0.00" );
            // if user entered at leat one grade...
            if( gradeCounter != 0 ) {
                // calculate average of all grades entered
                average = (double) total / gradeCounter;
                // display average with two digits of precision
                JOptionPane.showMessageDialog( null, "Class average is "
                        + twoDigits.format( average ), "Class Average",
                        JOptionPane.INFORMATION_MESSAGE );
            } // end 'if' part of if...else
            else // if no grades entered, output appropriate message
                JOptionPane.showMessageDialog( null, "No grades were entered",
                        "Class Average", JOptionPane.cINFORMATION_MESSAGE );
            System.exit( 0 );
    } // end main
    } // end class averageHere is the resulting output:
init:
deps-jar:

} // end main
C:\Java\Average2\src\average2\Main.java:75: '}' expected
} // end class average
3 errors
BUILD FAILED (total time: 2 seconds).
Can anyone tell me what I'm doing wrong?
Thanks in advance

Hmmm, I put the } in at the end of the code and that got rid of one of the bugs. code now reads:
package average2;
    import java.text.DecimalFormat;
    import java.swing.JOptionPane;
public class Main {
    public Main() {
    public static void main( String args[] )
            int total;          // sum of grades
            int gradeCounter;   // number of grades entered
            int grade;          // grade value
            double average;     // number with decimal point for average
            String gradeString; // grade typed by user
            // initialisation
            total = 0;          // initialise total
            gradeCounter = 0;   // initialise gradeCounter
            // processing phase
            // get first grade from user
            gradeString = JOptionPane.showInputDialog( "Enter Student Grade or -1 to Quit:" );
            // convert gradeString to int
            grade = Integer.parseInt( gradeString );
            // loop until sentinal value is reached
            while ( grade != -1 ) {
                total = total + grade;          // add grade to tatal
            gradeCounter = gradeCounter + 1;    // increment counter
            // get next grade from user
            gradeString = JOptionPane.showInputDialog( "Enter Student Grade or -1 to Quit:" );
            // convert gradeStrin to int
            grade = Integer.parseInt( gradeString );
        }   // end while
            // termination phase
            DecimalFormat twoDigits = new DecimalFormat( "0.00" );
            // if user entered at leat one grade...
            if( gradeCounter != 0 ) {
                // calculate average of all grades entered
                average = (double) total / gradeCounter;
                // display average with two digits of precision
                JOptionPane.showMessageDialog( null, "Class average is "
                        + twoDigits.format( average ), "Class Average",
                        JOptionPane.INFORMATION_MESSAGE );
            } // end 'if' part of if...else
            else // if no grades entered, output appropriate message
                JOptionPane.showMessageDialog( null, "No grades were entered",
                        "Class Average", JOptionPane.INFORMATION_MESSAGE );
            System.exit( 0 );
    } // end void main

I'm really sorry for being stupid. I'm just trying to understand what is going wrong. As soon as I get this sorted I can apply the principle to all other code I'm trying to write. I copied this code directly from my textbook used the SDK. Netbeans dosen't seem to like the way the textbook writes the code!
