描述

通过抽象函数定义一个模板，模板中定义抽象的函数。所有继承实现该类的子类都按照自己的实际需求实现其中的类，这样，就把这个抽象类当做了模板。

实例

//模板类public abstract class Game {   abstract void initialize();   abstract void startPlay();   abstract void endPlay();   //模板   public final void play(){      //初始化游戏      initialize();      //开始游戏      startPlay();      //结束游戏      endPlay();   }}//根据模板类实现实体类//实体类1public class Cricket extends Game {   @Override   void endPlay() {      System.out.println("Cricket Game Finished!");   }   @Override   void initialize() {      System.out.println("Cricket Game Initialized! Start playing.");   }   @Override   void startPlay() {      System.out.println("Cricket Game Started. Enjoy the game!");   }}//实体类2public class Football extends Game {   @Override   void endPlay() {      System.out.println("Football Game Finished!");   }   @Override   void initialize() {      System.out.println("Football Game Initialized! Start playing.");   }   @Override   void startPlay() {      System.out.println("Football Game Started. Enjoy the game!");   }}//主函数public class TemplatePatternDemo {   public static void main(String[] args) {      Game game = new Cricket();      game.play();      System.out.println();      game = new Football();      game.play();           }}输出结果：Cricket Game Initialized! Start playing.Cricket Game Started. Enjoy the game!Cricket Game Finished!Football Game Initialized! Start playing.Football Game Started. Enjoy the game!Football Game Finished!
