Hello people...i need help in my code. I have a confirm dialog below and it will ask you to repeat the program again. now my problem is that if i choose yes, it will exit the application. here's my code below.


import javax.swing.JOp tionPane;


public class palin {

public static void main (String args[]) {


String num, right, error, numint;
int number, num1, num2, num3, num4, num5;

numint = JOptionPane.sho wInputDialog( "Enter 5 digits:" );

number = Integer.parseIn t(numint);
num = number + "";
num1 = num.charAt(0);
num2 = num.charAt(1);
num3 = num.charAt(2);
num4 = num.charAt(3);
num5 = num.charAt(4);

right = "It is a PALINDROME!";
error = "It is NOT A PALINDROME!";

if (num1==num5 && num2==num4)
JOptionPane.sho wMessageDialog(
null, right, "Access Granted",
JOptionPane.INF ORMATION_MESSAG E);
else
JOptionPane.sho wMessageDialog(
null, error, "Access Denied",
JOptionPane.INF ORMATION_MESSAG E);

int choice = JOptionPane.sho wConfirmDialog (null, "Do you want to try it again?");
if (choice == JOptionPane.YES _OPTION)
System.exit(-1);

Use code tags when posting code
What do you think these lines tell the program to do?

[CODE=java] if (choice == JOptionPane.YES _OPTION)
System.exit(-1);[/CODE]

Well the important thing is not getting some lines of code, it's about understanding the code, so you can write your own anytime. Follow the logic of your code and try to understand what the statements in your code mean.
