## Java原型模式 ##

//首先，创建一个原型接口
    public interface Prototype {
          
        void setName(String name);  
        String getName();  
        void setAge(int age);  
        int getAge();  
        Prototype clone();  
    }
    //然后，实现一个具体的原型类
    public class Person implements Prototype {
          
        private String name;  
        private int age;  
          
        public Person(String name, int age) {
          
            this.name = name;  
            this.age = age;  
        }  
          
        @Override  
        public void setName(String name) {
          
            this.name = name;  
        }  
          
        @Override  
        public String getName() {
          
            return name;  
        }  
          
        @Override  
        public void setAge(int age) {
          
            this.age = age;  
        }  
          
        @Override  
        public int getAge() {
          
            return age;  
        }  
          
        @Override  
        public Prototype clone() {
          
            return (Prototype) super.clone();  
        }  
    }
    //最后可以使用Person类来创建对象，并通过克隆来创建新的对象
    public class Main {
          
        public static void main(String[] args) {
          
            Person person1 = new Person("Alice", 25);  
            Person person2 = person1.clone(); //克隆对象  
            person2.setName("Bob"); //修改新对象属性值  
            person2.setAge(30); //修改新对象属性值  
            System.out.println("person1 name: " + person1.getName()); //输出原对象属性值  
            System.out.println("person1 age: " + person1.getAge()); //输出原对象属性值  
            System.out.println("person2 name: " + person2.getName()); //输出新对象属性值  
            System.out.println("person2 age: " + person2.getAge()); //输出新对象属性值  
        }  
    }
