arrayindexreadonly.java

这是一个刚刚编写好的游戏:是贪吃蛇的游戏.很多人都玩过.应该不会很陌生.

public class ArrayIndexReadOnly{
	private int x;
	private int y;
	ArrayIndexReadOnly(int x,int y){
		this.x=x;
		this.y=y;
	}
	int getX(){
		return x;
	} 
	int getY(){
		return y;
	}
	public boolean equalOrRev(ArrayIndexReadOnly e){
		return ((e.getX()==getX())&&(e.getY()==getY()))
		||((e.getX()==getX())&&(e.getY()==-1*getY()))	
		||((e.getX()==-1*getX())&&(e.getY()==getY()));

	}
	public boolean equals(ArrayIndexReadOnly e){
		return(e.getX()==getX())&&(e.getY()==getY());
	}
	
	public boolean reverse(ArrayIndexReadOnly e){
		return ((e.getX()==getX())&&(e.getY()==-1*getY()))	
		||((e.getX()==-1*getX())&&(e.getY()==getY()));
	}	
}
