题目:Java中的对象反射机制是什么?有鼠么用?

解法:完全不了解,因为java编程经验太少,完全没用过。查了一些资料后,感觉反射机制是个强大并需要边用边体会的强大工具。能灵活处理各种动态类型下的问题。

代码:

 1 // 14.5 Tell me something about Object Reflection in java.
 2 // Answer:
 3 //    1. class type, constructor, member method, these are a few characteristics of a class
 4 //    2. the Object Reflection is a collection of tool classes, it is able to handle the situation when you know you want certain behavior, but don't know exactly what type of class you need.
 5 //    3. Unlike generics, it mainly deal with member methods and constructors, while generics focus more about data.
 6 //    4. you may get a specific constructor, a member method with customized constraints.
 7 public class TestJava {
 8     public static void main(String[] args) {
 9         return;
10     }
11 }
