Gui problem

[TexasNewbie]

Okay I thought I had this figured out....it gives the gui...but then on the coversion to capitol letters it gives me all kinds of exceptions

import javax.swing.JOp tionPane; //GUI support


public class UpperCase
{

public static void main(String[] args)
{
String s;

s = JOptionPane.sho wInputDialog("E nter any characters:");

int x = Integer.parseIn t (s);


System.out.prin tln("You entered " + x + ".");
// Convert to upper case
String upper = s.toUpperCase() ;

}
}

If you enter digits it should work OK although the toUpperCase() would have no effect.

If you enter letters the Integer.parseIn t (s) would give a NumberFormatExc eption.

what should your input be, digits or letters?

Either, The over all outcome should be that the lowercase letter covert to upper case.

Got it figured out thanks for the help.
