对象克隆技术

package org.lxh.demo11.demo;

class Person implements Cloneable{
private String name = null;
public Person(String name){
this.name = name;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}

public Object clone() throws CloneNotSupportedException{
return super.clone();
}
public String toString(){
return "name: "+this.getName();
}

}

public class Demo05 {
public static void main(String args[]) throws CloneNotSupportedException {
Person per1 = new Person("zhangsan");
Person per2 = (Person)per1.clone();
((Person) per2).setName("lisi");s
System.out.println("former:"+per1);
System.out.println("later :"+per2);
}
}

此字段最重要的语句：1、public Object clone() throws CloneNotSupportedException；

2、public static void main(String args[]) throws CloneNotSupportedException {
