请帮忙哈,该如何解决

请帮忙哈
public class Point
  { 
     int x,y;
      Point()
{     this(12,15);
         }
      Point(int a,int b)
{
        x=a;
        y=b;
             }
      void getpoint()
 {
           System.out.println("点("+x+","+y+")");
        }
    void  getpoint(int c,int d)
 {
         x=c;
         y=d;
       System.out.println("点("+x+","+y+")");
    }
      public static void main(String [] args)
    {
         Point p1=new Point();
         Point p2=new Point(10,20);
         p1.getpoint();
         p1.getpoint(15,20); 
         p2.getpoint();
         p2.getpoint(25,30);
       }
}跪求谁帮忙调试哈，它总是提示找不到main class 调试
[解决办法]
代码没有错
public class Point
  { 
     int x,y;
      public Point()
{     this(12,15);
         }
      Point(int a,int b)
{
        x=a;
        y=b;
             }
      void getpoint()
 {
           System.out.println("点("+x+","+y+")");
        }
    void  getpoint(int c,int d)
 {
         x=c;
         y=d;
       System.out.println("点("+x+","+y+")");
    }
      public static void main(String [] args)
    {
         Point p1=new Point();
         Point p2=new Point(10,20);
         p1.getpoint();
         p1.getpoint(15,20); 
         p2.getpoint();

         p2.getpoint(25,30);
       }
}
[解决办法]
你还是用eclipse，netbeans之类的ide工具吧。。。
[解决办法]
代码格式化！！
[解决办法]
格式化代码：

package cn.hafx;

public class Point
{
    int x, y;

    Point()
    {
        this(12, 15);
    }

    Point(int a, int b)
    {
        x = a;
        y = b;
    }

    void getpoint()
    {
        System.out.println("点(" + x + "," + y + ")");
    }

    void getpoint(int c, int d)
    {
        x = c;
        y = d;
        System.out.println("点(" + x + "," + y + ")");
    }

    public static void main(String[] args)
    {
        Point p1 = new Point();
        Point p2 = new Point(10, 20);
        p1.getpoint();
        p1.getpoint(15, 20);
        p2.getpoint();
        p2.getpoint(25, 30);
    }
}
