Much Easier:

To get an int: sc.nextInt();

To get a char: sc.next().charAt(0);

To get a double: sc.nextDouble();

See, no parsing... Much less confusing and less typing

How do you have the program say what us your nem? And you reply your name and the have it say hello (name)?

@leemorethomas old school? lol.. im doing a degree in Computer Science and Artificial Intelligence.. Keyboard is very handy for students.. plus in real life you will barely need the use of such a thing like scanner and Keyboard. because any modern program would take inputs from GUI..

@drinu93 Keyboard is old school. I'm guessing Your Senior. Let me know if you need Junior assistance to ease the load. I love Java.

Ok... i've spent the past 30 minutes just trying to find how to parseInt. (syntax) and this is the first tutorial/info that has made any sense to me. I wasn't putting Integer.parseInt, i was putting the string, st2.nextToken().parseInt. LOL fail. THANK YOU FOR SAVING MY SANITY :)

just use the Keyboard Class.. you can find it on the net.. no need for inports of initializing just 1 line ex:

System.out.print("enter name ");

String name = Keyboard.readString();

just download that :)
