move.java

实现火星车,全部由java写成

package cn.nasa;

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

	@Override
	public Object exec()  {
		coordinate.add(direction.getX_offset(),direction.getY_offset());
		return coordinate;
	}

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

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

}
