Java writing greedy Snake games _java

Don't say much nonsense, directly to the code:

  The public Panel () {//TODO auto-generated constructor stub} is public void Reset () {snake.clear ();

Snakebody.java

Package snake;

  int x;
  int y;

    x = 0;
    y = 0;
  }
   
  Public snakebody (int a,int b) {
    x = A;
    y = b;
  }
  Public Snakebody (Snakebody SB) {This
    (SB.X,SB.Y);
  }
   
  public void Turnup () {
    y--;
  }
  public void Turndown () {
    y++;
  }
  public void TurnLeft () {
    x--;
  }
  public void TurnRight () {
    x + +;
  }
   
  Boolean equals (Snakebody s) {
    if (x==s.x) && (Y==S.Y)) return true;
    else return          false;
  }
 

The above is described in this article to share the greedy snake all the code, I hope to be able to master Java Help.
