Re: Java code Question

Note that you shouldn't have System.exit(1) in there. It isn't needed as the main method is about to terminate anyway, and the value 1 is used to indicate an unexpected termination. If you feel you have to have it, use System.exit(0) instead.

You'll have to convert your char digit to an int to use as the limit of an inner loop. Something like:
int reps = Integer.parseInt(Character.toString(digit));
but there has to be a better way - help me Roedy!

BTW, it's nice to have a name - who are you?

I have to do this assignment:

Write a program that reads a social security number written as contiguous
digits (for instance, 509435456), uses the charAt method to obtain each
character and then prints each digit on a separate line followed by a colon
and the digit printed the number of times equal to its value. Thus the output
for 509435456 would be

 5:55555
 0:
 9:999999999
 4:4444
 3:333
 5:55555
 4:4444
 5:55555
 6:666666

So far I have gotten this far:



import javax.swing.JOptionPane;

public class Prog3
//Assignment # 3
{
public static void main(String[] asd)
{ String s = JOptionPane.showInputDialog("Type Your Social Security Number
Here:");
int len = s.length();
char digit;
for(int j =0; j < len; j++)
{
digit = s.charAt(j);
System.out.println(digit);
}
System.out.println();//seoparates ouutput from "To continue.." message
System.exit(1);
}
}

and I get the numbers going down.
What do i do next?
