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
------解决方案--------------------
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();
