About JOptionPane.showMessageDialog
Hi I was wondering if I could use a for(){} in a JOptionPane.showMessageDialog.To explain,let's say I have an array A,full of integers,and have done two different equations using the numbers from A and stored the the results in two arrays B,C one for each equation.Can I use one message box to print all the results in a form like this:
Number: ......
Result for equation no.1: ......
Result for equation no.2: ......
So it becomes like this in the message box:
Number: ......
Result for equation no.1: ......
Result for equation no.2: ......
Number: ......
Result for equation no.1: ......
Result for equation no.2: ......
Number: ......
Result for equation no.1: ......
Result for equation no.2: ......
Number: ......
Result for equation no.1: ......
Result for equation no.2: ......
..................................
Can I do this????Is there any way?Perhaps another message dialog command from another library that supports many results?
Regards,Nick

JLabel supports html 3.2 (roughly).
Another option is to make up your own JDialog for this.
Java Code:// intiialize your_components // add listeners as needed JDialog dialog = new JDialog(new Frame()); dialog.getContentPane().add(your_components) dialog.pack(); dialog.setLocation(...) dialog.setVisible(true); // carry on as desired..
Java Code:import javax.swing.*; import java.util.Arrays; // j2se 1.5+ public class OptionsTest { public static void main(String[] args) { int[] data = { 2, 3, 4, 5 }; int[] squares = getSquares(data); int[] cubes = getCubes(data); System.out.printf("squares = %s%n", Arrays.toString(squares)); System.out.printf("cubes = %s%n", Arrays.toString(cubes)); String s = formatResults(data, squares, cubes); JOptionPane.showMessageDialog(null, new JLabel(s), "Results", JOptionPane.PLAIN_MESSAGE); } static private int[] getSquares(int[] input) { int[] out = new int[input.length]; for(int j = 0; j < input.length; j++) { out[j] = input[j]*input[j]; } return out; } static private int[] getCubes(int[] input) { int[] out = new int[input.length]; for(int j = 0; j < input.length; j++) { out[j] = input[j]*input[j]*input[j]; } return out; } static String formatResults(int[] input, int[] one, int[] two) { // StringBuffer is the legacy alternative for j2se 1.4-. StringBuilder sb = new StringBuilder("<html>"); for(int j = 0; j < input.length; j++) { sb.append("Number: " + input[j] + "<br>"); sb.append("Result for equation no.1: " + one[j] + "<br>"); sb.append("Result for equation no.2: " + two[j] + "<br><br>"); } return sb.toString(); } }

I guess that the new dialog idea would be better since i don't know html apart from a little here and there.So I'll search around and try that
Thx man!!!!!
