设计模式-原型模式示例

// 原型接口
public interface Prototype {
    Prototype clone();
}

// 具体的学生类，实现原型接口并重写复制方法
public class Student implements Prototype {
    private String name;
    private int age;
    
    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
    
    public int getAge() {
        return age;
    }
    
    public void setAge(int age) {
        this.age = age;
    }
    
    // 实现 clone() 方法，返回一个新的学生对象并复制原有对象的属性
    @Override
    public Prototype clone() {
        return new Student(name, age);
    }
}

// 客户端代码
public class Client {
    public static void main(String[] args) {
        // 创建原型对象
        Student stu1 = new Student("张三", 20);
        
        // 克隆新对象并修改属性
        Student stu2 = (Student) stu1.clone();
        stu2.setName("李四");
        stu2.setAge(21);
        
        // 打印结果
        System.out.println("stu1: " + stu1.getName() + ", " + stu1.getAge());
        System.out.println("stu2: " + stu2.getName() + ", " + stu2.getAge());
    }
}
