利用java.lang.reflect.Constructor动态实例化对象

 1 public class Student {
 2     private String name;
 3     private Integer age;
 4     private Student(String name,Integer age){
 5         this.name=name;
 6         this.age=age;
 7     }
 8     public String getName() {
 9         return name;
10     }
11     public void setName(String name) {
12         this.name = name;
13     }
14     public Integer getAge() {
15         return age;
16     }
17     public void setAge(Integer age) {
18         this.age = age;
19     }
20 }
