[SOLVED] \t not working correctly?

[Gakusei]

Hi everyone, I'm having a bit of trouble with "\t" for some reason.

This is what I'm trying to output:

Code:

N    10*N    100*N    1000*N

1    10      100      1000
2    20      200      2000
3    30      300      3000
4    40      400      4000
5    50      500      5000

My code works fine except that it doesn't put the tab doesn't show up.
Here is my code:

Code:

import javax.swing.JOptionPane;

public class Ex6 {
    public static void main(String args[]) {
        String msg;
        
        msg = "N\t10*N\t100*N\t1000*N\n\n";         // \t doesn't seem to be working for some reason...
        
        for (int i = 1; i <= 5; i++) {
            msg += String.format("%d\t%d\t%d\t%d\n", i, i*10, i*100, i*1000);
        }
        
        JOptionPane.showMessageDialog(null, msg);
    }
}

And this is what I get:

Code:

N10*N100*N1000*N

1101001000
2202002000
3303003000
4404004000
5505005000

Does anyone happen to know what the problem is here?

Actually it works but not in the GUI. It works at the console.

Code:

import javax.swing.JOptionPane;

public class Ex6
{
    public static void main(String args[])
    {
        String msg;

        msg = "N\t10*N\t100*N\t1000*N\n\n"; // \t doesn't seem to be working for some reason...

        for (int i = 1; i <= 5; i++)
        {
            msg += String.format("%d\t%d\t%d\t%d\n", i, i * 10, i * 100, i * 1000);
        }

        System.out.println(msg);
        JOptionPane.showMessageDialog(null, msg);
    }
}

Code:

import javax.swing.JOptionPane;

public class Ex6Rx {
    public static void main(String args[]) {
        String msg;

        msg = String.format("%11sN%9s10*N%5s100*N%3s1000*N\n",
                            "", "", "", "");

        for (int i = 1; i <= 5; i++) {
            msg += String.format("%12d%12d%12d%12d\n",
                                  i, i*10, i*100, i*1000);
        }

        JOptionPane.showMessageDialog(null, msg, "", -1);
    }
}

Weird that it works in the console but not in the GUI.

Thanks for the reply, hardwired, that method worked. It also worked when I used the tab key in place of the "\t"s.

String.format("%d\t%d\t%d\t%d\n", i, i*10, i*100, i*1000);

Have you tried also to put some whitespace?

Like,

Quote:

%d \t %d \t %d \t %d\n

Have you also test it like that?

[Gakusei]

I just tried doing with the whitespace

Quote:

%d \t %d \t %d \t %d\n

The spaces show up, but it seems like \t is completely ignored.
