反射demo（二）

=============Person 类=============

package com.fanshe;

public class Person {
 private String name;
 int age;
 public String address;

 public Person(){}
 private Person(String name){
  this.name = name;
 }
 public Person(String name,int age,String address){
  this.name=name;
  this.age = age;
  this.address = address;
 }

 @Override
 public String toString() {
  return "Person [name=" + name + ", age=" + age + ", address=" + address
    + "]";
 }
}
===========反射类===============

package com.fanshe;

import java.lang.reflect.Constructor;

public class ReflectDemo {

 public static void main(String[] args) throws Exception {
  Class c1 = Class.forName("com.fanshe.Person");
  
  Constructor con = c1.getConstructor(String.class,int.class,String.class);
  Object obj = con.newInstance("zx",26,"北京");
  System.out.println(obj.toString());
 }

}

==============================
结果：

Person [name=zx, age=26, address=北京]
