原型模式

1：原型模式可以理解为克隆
    java里面提供了一个借口cloneable，实现这个接口就意味这个类可以被克隆！
    现在我已经迫不急待的克隆出多个我来了，一个在上学，一个在家里面多好啊！
    开始吧

    package cn.tsp2c.ljz.prototypepattern;

public class Person implements Cloneable{
    private double height;
    private double weight;
   
    public double getHeight() {
return height;
}

public void setHeight(double height) {
this.height = height;
}

public double getWeight() {
return weight;
}

public void setWeight(double weight) {
this.weight = weight;
}

public Person(double height,double weight){
    this.height = height;
    this.weight = weight;   
    }
   
    public Object close(Person p){
    return (Object)p;
    }
    public Object close(){
    Person p = new Person(height,weight);
    return (Object)p;
    }
   
}



package cn.tsp2c.ljz.prototypepattern;

public class Main {
    public static void main(String[] args) {
  Person p = new Person(165,52);
  Person p2 = (Person)p.close(p);
  System.out.println("第一个人身高"+p.getHeight());
  System.out.println("第二个人身高"+p2.getHeight());
}
}

输出的结果都一样，可知克隆成功
