giver fejl når jeg vil execute?

import java.awt.*;

public class Punkt
{
    public static void main(String[] args)
    {
        Point p;
        p = new Point();

        int a;
        a = p.x;

        System.out.println("a: "+a);

        System.out.println("x-koordinat: "+p.x);
        System.out.println("y-koordinat: "+p.y);

        p.x = 110;
        p.y = 210;

        System.out.println("x-koordinat: "+p.x);
        System.out.println("y-koordinat: "+p.y);

        p.move(200,300);

        System.out.println("x-koordinat: "+p.x);
        System.out.println("y-koordinat: "+p.y);

        p.x = p.x + 5;

        System.out.println("x-koordinat: "+p.x);
        System.out.println("y-koordinat: "+p.y);

        p.translate(-10,20);

        System.out.println("x-koordinat: "+p.x);
        System.out.println("y-koordinat: "+p.y);
    }
}

det giver fejl?
