关于Java 设计模式 模板模式 Template

1、CarModel.java

package com.ssm.cts.pattern.template;

public abstract class CarModel {
  
  // 启动
  public abstract void start();

  // 停止
  public abstract void stop();

  // 喇叭声音
  public abstract void alarm();

  // 引擎声音
  public abstract void engineBoom();

  // 运行
  public void run(){
    this.start();
    
    this.engineBoom();
    
    this.alarm();
    
    this.stop();
  }
  
}

2、BenzModel.java

package com.ssm.cts.pattern.template;

public class BenzModel extends CarModel {

  @Override
  public void alarm() {
    System.out.println("奔驰：喇叭声音...");
  }

  @Override
  public void engineBoom() {
    System.out.println("奔驰：引擎音声音...");
  }

  @Override
  public void start() {
    System.out.println("奔驰：启动...");
  }

  @Override
  public void stop() {
    System.out.println("奔驰：停止");
  }

}

3、BMWModel.java

package com.ssm.cts.pattern.template;

public class BMWModel extends CarModel {

  @Override
  public void alarm() {
    System.out.println("宝马：喇叭声音...");
  }

  @Override
  public void engineBoom() {
    System.out.println("宝马：引擎音声音...");
  }

  @Override
  public void start() {
    System.out.println("宝马：启动...");
  }

  @Override
  public void stop() {
    System.out.println("宝马：停止");
  }

}

4、Demo.java

package com.ssm.cts.pattern.template;

public class Demo {

  // 测试
  public static void main(String[] args) {
    CarModel car = new BenzModel();

    car.run();
  }

}
