Displaying numbers per line on a JOptionPane.showMessageDialog screen

[zoe]

Hi, I am trying to have my program output all the even numbers from 0-500 displaying 5 numbers per line on a JOptionPane.showMessageDialog screen. I can get it to output one number each output box but you need to keep hitting ok. I was thinking of using modulus in an if loop.

Something like

If (count % 5 == 0);
temp = temp + "/n";

maybe?

Here is what I have at the moment. I am really stuck on how to implement the return character.

import javax.swing.JOptionPane;

public class Counting
{
public static void main(String args[])
{
String temp;
int count=0;

while (count <= 400)
{
JOptionPane.showMessageDialog(null, "The output is "+ count);
count = count + 2;
}
if (count % 5 == 0);
temp = temp + "/n";
System.exit(0);
}

}

Thanks.

import javax.swing.JOptionPane;

public class CountingRx
{
    public static void main(String args[])
    {
        String temp = "";
        int count=0;
        int j = 1;

        while (j <= 50)
        {
            j++;
            
            if(j % 2 == 0)    // test for an even number
            {
                count++;
                temp += " " + j;
                if(count % 5 == 0)
                    temp = temp + "\n";
            }
        }
        JOptionPane.showMessageDialog(null, "The output is "+ temp);
        System.exit(0);
    }
}
