Clone:
构建一个对象的时候，是不是一定要调用构造函数！
package com.edu.test;
public class Zhenzhen implements Cloneable{
public Zhenzhen(){
System.out.println("new Instance");
}
public String name;
public String female;
public static void main(String[] args) throws Exception {
Zhenzhen z = new Zhenzhen();
z.name="李珍";
z.female="女妖";
Zhenzhen nz = (Zhenzhen)z.clone();
System.out.println(nz.name+" "+nz.female);
System.out.println(z);
System.out.println(nz);
}
}
Example:
while(rs.next)(){
Userinfo info = new Userinfo();
info.setUname(rs.getString(2));
info.setUpass(rs.getString(3));
}
