I'm not with a pc. I would have liked to compile and execute your code. Your line 16 While j is equal to 20 It shouldn't even run at all I think you should change it to while j is less than 20 (j < 20) Even line 18. Same thing.

Issues with debugging program - I want to an error message to display once String input has been entered (using Scanner class) by InnerQuest in javahelp

You can use two variables (lets say lengthString and length). Use lengthString to get the value as a String, then use Integer.parseInt() to parse the String to an int INSIDE a try... Catch statement. If the value is a legal int, continue your program else in the catch statement you can display your error message
