介绍

代码

游戏模板类

定义一个游戏模板虚类 Game，抽象并规范好游戏的进行流程

public abstract class Game {
    abstract void init();

    abstract void startPlay();

    abstract void endPlay();

    // 模板
    public final void play(){
        // 初始化
        init();

        // 开始
        startPlay();

        // 结束
        endPlay();
    }
}

实体类

建立实体类 Cricket

public class Cricket extends Game{
    @Override
    void init() {
        System.out.println("Cricket init");
    }

    @Override
    void startPlay() {
        System.out.println("Cricket start");
    }

    @Override
    void endPlay() {
        System.out.println("Cricket end");
    }
}

建立实体类 Football

public class Football extends Game{
    @Override
    void init() {
        System.out.println("Football init");
    }

    @Override
    void startPlay() {
        System.out.println("Football start");
    }

    @Override
    void endPlay() {
        System.out.println("Football end");
    }
}

测试

public class TemplateTest {
    @Test
    void test(){
        Game game = new Cricket();
        game.play();
        System.out.println("------------------");

        game = new Football();
        game.play();
    }
}
