java-programmer, Learning Arrays Hi, I am just learning arrays and I am trying to get this 2D array to print
out like this:

0 1 2 3 4 5 6
0 1 2 3 4 5 6
0 1 2 3 4 5 6
0 1 2 3 4 5 6
0 1 2 3 4 5 6

but insteads it prints out like this: 0 1 2 3 4 5 6 0 1 2 3 4 5 6 0 1 2 3 4
5 6 0 1 2 3 4 5 6 0 1 2 3 4 5 6

I can get it to work with system.out.println but I need to use a
JOptionPane.showMessageDialog box as I have attempted to do. Any ideas?
(my code is below) Thanks!!!!!!!!!!

import javax.swing.*;

public class array5by7{

public static void main (String args[]){

String outputString = "";

int table[][] = new int [5][7];

for (int row=0; row<table.length; row++)
{
for (int col = 0; col <table[row].length; col++)
table[row][col] = 0 + col;
}



for (int row=0; row<table.length; row++)
{
for (int col = 0; col<table[row].length; col++)
outputString += (table[row][col] + " ");
}

JOptionPane.showMessageDialog (null, outputString + "\n");


}


}

<snip>

More portable would be: System.getProperty("line.separator") instead of
hardcoding "\n", but hey, we all do it.
