coordinate.java

实现火星车,全部由java写成

package cn.nasa;

public class Coordinate {
	private int x_coordinate;
	private int y_coordinate;
	
	public int getX_coordinate() {
		return x_coordinate;
	}
	
	public int getY_coordinate() {
		return y_coordinate;
	}
	
	public  Coordinate(int x,int y) {
		this.x_coordinate = x;
		this.y_coordinate = y;
	}
	
	public void add(int x,int y){
		this.x_coordinate+=x;
		this.y_coordinate+=y;
		System.out.println(x_coordinate+" , "+y_coordinate);
		
	}
	
}
