Doing this in a GUI builder is not particularly a good idea, as no human is able to read and debug it and we can't help you on DIC...

Alright, well there is a good tutorial provided by Sun that I urge you to read:
http://download.orac...s/progress.html
It does involve a bit of threading using SwingWorker, but I'm sure the tutorial will cover it.

Ok, no need to post non-code in code tags...It's very distracting. If you want a String to be a char[], you can always use the toCharArray() method. And if you want to convert a char[] to a String, you pass it into a String constructor.
If you want to convert a single character from a String, use the charAt(). To do it the other way around, you can either cast it or use the Character.toString() method.
char[] chars = string.toCharArray(); String newStr = new String(chars);
If you want to convert a single character from a String, use the charAt(). To do it the other way around, you can either cast it or use the Character.toString() method.
char firstLetter = string.charAt(0);
String aLetter = 'c' + "";
String anotherLetter = Character.toString('v');
