java学习——克隆

public class Person implements Cloneable {// 必须实现Cloneable接口

private String name=null;

public Person(String name){

this.name= name;

}

public void setName(String name){

this.name= name;

}

public String getName() {

returnname;

}

// 需要子类覆写clone方法

@Override

protected Object clone() throws CloneNotSupportedException {

return super.clone();//具体的克隆操作由父类完成

}

public String toString() {

return"姓名："+this.name;

}

}

/*克隆*/

Person p1 =new Person("张三");

Person p2 =null;

try{

p2 = (Person) p1.clone();

}catch(CloneNotSupportedException e) {

e.printStackTrace();

}

p2.setName("李四");

System.out.println("原始对象："+ p1);

System.out.println("克隆之后的对象："+ p2);
