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();
}
}
public 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!");
}
}
Football.java
public 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!");
}
}
步骤 3
使用 Game 的模板方法 play() 来演示游戏的定义方式。
TemplatePatternDemo.java
public class TemplatePatternDemo {
public static void main(String[] args) {
Game game = new Cricket();
game.play();
System.out.println();
game = new Football();
game.play();
}
}
