面试题复习-常用设计模式-策略模式

策略接口：

package com.ajax.pattern.strategy;

public interface EatWay {
    void cook();
}

策略1：

package com.ajax.pattern.strategy;

public class Fry implements EatWay {
    @Override
    public void cook() {
        System.out.println("炸");
    }
}

策略2：

package com.ajax.pattern.strategy;

public class Cook implements EatWay {
    @Override
    public void cook() {
        System.out.println("煮");
    }
}

环境：

package com.ajax.pattern.strategy;

import lombok.AllArgsConstructor;

@AllArgsConstructor
public class Chicken {
    private EatWay eatWay;

    public void cook() {
        System.out.println("准备");
        eatWay.cook();
    }    
}

运行：

package com.ajax.pattern.strategy;

public class Run {
    public static void main(String[] args) {
        Chicken chicken = new Chicken(new Fry());
        chicken.cook();
    }
}
