Please help me in robocode java wave surfing

[jhumar regaspi]

This is the code:

package Robot;
import robocode.*;
import robocode.util.Utils;
import java.awt.geom.*;     
import java.util.ArrayList; 

public class Noblesse extends Robot
{

public static int BINS = 47;
    public static double _surfStats[] = new double[BINS];
    public Point2D.Double _myLocation;     // our bot's location
    public Point2D.Double _enemyLocation;  // enemy bot's location
 
    public ArrayList<?> _enemyWaves;
    public ArrayList<?> _surfDirections;
    public ArrayList<?>_surfAbsBearings;
 
    public static double _oppEnergy = 100.0;
 
   /** This is a rectangle that represents an 800x600 battle field,
    * used for a simple, iterative WallSmoothing method (by PEZ).
    * If you're not familiar with WallSmoothing, the wall stick indicates
    * the amount of space we try to always have on either end of the tank
    * (extending straight out the front or back) before touching a wall.
    */
    public static Rectangle2D.Double _fieldRect
        = new java.awt.geom.Rectangle2D.Double(18, 18, 764, 564);
    public static double WALL_STICK = 160;
 
    public void run() {
        _enemyWaves = new ArrayList();
        _surfDirections = new ArrayList();
        _surfAbsBearings = new ArrayList();
 
        setAdjustGunForRobotTurn(true);
        setAdjustRadarForGunTurn(true);
 
        do {
             turnRadarRightRadians(Double.POSITIVE_INFINITY);
        } while (true);
    }
	}	

This is the error:

can somebody help me.. I'm only a beginner hoping to become pro programmer..

The error message tells you exactly what is wrong.

4. ERROR in C:\robocode\robots\Robot\Noblesse.java (at line 40)
turnRadarRightRadians(Double.POSITIVE_INFINITY);
^^^^^^^^^^^^^^^^^^^^^
The method turnRadarRightRadians(double) is undefined for the type Noblesse

There is no method called "turnRadarRightRadians" that takes a double. There are two ways to fix it:

1) Don't call the (non-existent) method
2) Define the method.
