Hey there everyone. I David. I am have a problem with the end of line keystroke ( Ctrl+Z ) in the Netbeans and JBuilder Compiler, when I press the buttons simultaneously nothing happens but when I do it in Eclipse it works fine. Here is a look at the code.Help is gladly appreciated.

IDE provides output window but it is not a console command prompt. So try to run your console application at command prompt.
