My goal is to take a string of numbers separated by commas
then read that string and have the string show the
individual numbers as in an array. This is a small
demo of my problem.

Seehttp://mindprod.com/jgloss/csv.html
if you have whole files of these.

See Regex.split for a single line an no complications like a comma
escape mechanism.  Seehttp://mindprod.com/jgloss/regex.html

Hi Roedy,
Thanks for stopping by. I have downloaded both of your
recommendations.
For me your gifts make the task in my Q both possible/easier, with
some
other "gift's" included.

I have finished this task of my original Q in a more cluttered way.
What you write reduces the code needed for the task and
to more adjustments of varied input.

Thanks again.

import javax.swing.*;

public class Whatsup extends JFrame {
JPanel infoPanel= new JPanel();

void Whatsup() {

String cStr, qStr = "";

int arryCnt = 0;
int x = 0;
int t = 0;
int sho = 0;
//a string with no spaces in between.
cStr = "84,104,101,32,67,108,111,99,10";
// first count a number needed for the array
for (int i = 0;i<cStr.length();i++){
if (cStr.charAt(i)== 44){ // look for the number of commas
arryCnt++;
}
}
// this is the array with the number needed
Integer cInt[] = new Integer [arryCnt+1];

// parse for ints
for (int ia = 0;ia<cStr.length();ia++){
