=============Person 類=============

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
+ "]";
}
}
===========反射類===============

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());
}

}

==============================
結果：

Person [name=zx, age=26, address=北京]
