关于Java 设计模式 原型模式 Prototype

1、Car.java

package com.ssm.cts.pattern.prototype;

import java.util.ArrayList;

public class Car implements Cloneable {

  private ArrayList<String> arrayList = new ArrayList<String>();

  @Override
  public Car clone() {
    Car car = null;
    try {
      car = (Car) super.clone();
    } catch (CloneNotSupportedException e) {
      e.printStackTrace();
    }
    return car;
  }

  public void setValue(String value) {
    this.arrayList.add(value);
  }

  public ArrayList<String> getValue() {
    return this.arrayList;
  }
}

2、Demo.java

package com.ssm.cts.pattern.prototype;

public class Demo {

  // 测试
  public static void main(String[] args) {
    // 生成对象
    Car car = new Car();
    car.setValue("别克");
    
    // 复制对象
    Car cloneThing = car.clone();
    cloneThing.setValue("奥迪");
    
    System.out.println(car.getValue());
  }

}
