<indentifier> expected error

[greekgod8591]

Hey,
Our team is using our robot from last year and trying to test out and get ourselves a taste of the java. We are just trying to make a SimpleRobot and we can't get past this error.

C:\Users\Alex\Documents\NetBeansProjects\TestProje ct\src\edu\wpi\first\wpilibj\templates\2577_V1.jav a:21: <identifier> expected
public class 2577_V1 extends SimpleRobot {

our code:

import edu.wpi.first.wpilibj.SimpleRobot;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.RobotDrive;

public class 2577_V1 extends SimpleRobot {

RobotDrive rDrive = new RobotDrive(1,2,3,4);
Joystick lStick = new Joystick(1);
Joystick rStick = new Joystick(2);

public void autonomous() {

}

public void operatorControl() {



while(true && isEnabled() && isOperatorControl()) {
rDrive.tankDrive(lStick, rStick);
}

}
}

any help would be much appreciated!
