5 errors, who can help me?

Can someone tell me the problem here?? I dont get it :S

Compiling...

This is my code:

package MyRobots;

import robocode.HitRobotEvent; import robocode.Robot; import robocode.ScannedRobotEvent;

import java.awt.*;

public class Yeah extends Robot {

public void run() { // Kleuren setBodyColor(Color.black); setGunColor(Color.black); setRadarColor(Color.black); setBulletColor(Color.black); setScanColor(Color.cyan);

// ...

   turnRadarRightRadians(Double.POSITIVE_INFINITY);
   do {
       // Check for new targets.
       // Only necessary for Narrow Lock because sometimes our radar is already
       // pointed at the enemy and our onScannedRobot code doesn't end up telling
       // it to turn, so the system doesn't automatically call scan() for us
       // [see the javadocs for scan()].
       scan();
   } while (true);

}

public void onScannedRobot(ScannedRobotEvent e) {

   double radarTurn =
       // Absolute bearing to target
       getHeadingRadians() + e.getBearingRadians()
       // Subtract current radar heading to get turn required
       - getRadarHeadingRadians();

   setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

   // ...

}

give me the source code And Ill Try To fix it

package MyRobots;

import robocode.AdvancedRobot; import robocode.ScannedRobotEvent; import robocode.util.Utils;

public class Yeah extends AdvancedRobot {

public void run() {

   turnRadarRightRadians(Double.POSITIVE_INFINITY);
   do {
       scan();
   } while (true);

}

public void onScannedRobot(ScannedRobotEvent e) {

   double radarTurn =
       // Absolute bearing to target
       getHeadingRadians() + e.getBearingRadians()
       // Subtract current radar heading to get turn required
       - getRadarHeadingRadians();

   setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

}

}

Nevermind, i fixed it already. Still thanks for your help
