parser.java

实现火星车,全部由java写成

package cn.nasa;

import java.util.HashMap;
import java.util.Map;

public class Parser {
	Map<String,IAction> map=new HashMap<String, IAction>();
	IAction left=new Left(),right=new Right(),move=new Move();
	Parser(){
		map.put("L", left);
		map.put("R", right);
		map.put("M", move);
	}
	
	public IAction getinput(String word){
		return map.get(word);
	}	

}
