left.java

实现火星车,全部由java写成

package cn.nasa;

public class Left implements IAction {
	private Direction direction;
	private Coordinate coordinate;

	@Override
	public Object exec() {
		direction=direction.TurnLeft();
		return direction;
	}

	@Override
	public void setcoordinate(Coordinate coordinate) {
		this.coordinate=coordinate;
	}

	@Override
	public void setdirection(Direction direction) {
		this.direction=direction;
	}

}
