Think about what's happening. When you push forwards on the joystick, the RobotDrive tells both motors (1 and 2) to drive forward, which works fine. Likewise, pulling the joystick backwards makes both motors go backwards.

But if you want to turn left (spin in place) then one motor has to go forwards and one has to go backwards. In this case, it picked the wrong ones, and as a result spins in the wrong direction. By switching the order you pass in the motors, you'll switch it's choice and it'll turn in the right direction.

What you say makes a lot of sense, but i remember that we tried doing it today and it didnt work..
I dont have the robot now to try it but i will try it tomorrow and see if it works.

by the way, i remember when we used labview, it had a robot simulator, does java has something like that too?

There isn't an official java simulator like there is for LabVIEW.

I've seen a few different attempts where people have tried to put one together, for example http://www.chiefdelphi.com/forums/sh...d.php?t=112024, but I have not tried any of them.
