A detailed explanation of Java reflection Mechanism and example code _java

Java Reflection Mechanism:

Testing entity Classes

Taking human as an example

/** * PROJECT:DAY12_FOR_LXY * created:lulu * DATE:2016/8/10/public class Human<t> {private String name
  ;
  private int age;

  private float height;
  private static int legs = 2;
  Private map<string, string> jobs;

  Private T T;
    public int Say () {System.out.println ("I ' m" + name);
  return 0;
  } private void Sleep (Human Human) {System.out.println (name + ' sleep with ' + human.name);
  Public list<integer> GetList () {return new arraylist<> ();
    Public Human () {} private Human (String name, int age, float height) {this.name = name;
    This.age = age;
  This.height = height;
  Public String GetName () {return name;
  public void SetName (String name) {this.name = name;
  public int getage () {return age;  public void Setage (int age) {if (Age >/Age < 0) {throw new RuntimeException (' Age > 150 | |
    Age < 0 ");
  } This.age = age; } Public Float GEtheight () {return height;
  public void SetHeight (float height) {this.height = height; 
        @Override public String toString () {return "human{" + "Name= '" + name + ' \ ' + ", age=" + Age +
  ", height=" + Height + '} ';

 }
}

Test Get construct method

/** * PROJECT:DAY12_FOR_LXY * Created:lulu * DATE:2016/8/10////////* Get Construction Method/public class TestConstructor {Publ
    IC static void Main (string[] args) {//get the corresponding class structure, which is used to describe Human class class 

test get field

/** * PROJECT:DAY12_FOR_LXY * Created:lulu * DATE:2016/8/10/* Get Properties: properties include: (  Property name type modifier generic) The property of the parent class/public class Testfield {public static void main (string[] args) {class 

test Fetch method

/** * PROJECT:DAY12_FOR_LXY * Created:lulu * DATE:2016/8/10///* Fetch method: Method name modifier Returns a call to a generic static and Non-static method of a value type * * Publi
    C class TestMethod {public static void main (string[] args) {class 

Test Get class Information

public static void Main (string[] args) {
  printclassinfo (student.class);
}

The class of the only parent class in the public static void Printclassinfo (Class C) {
    //java object
    System.out.println (C.getname ());
    System.out.println (C.getsimplename ());
    System.out.println (C.getsuperclass ());

    Class[] interfaces = C.getinterfaces ();
    for (Class aninterface:interfaces) {
      System.out.println (aninterface);
    }
    The outer class class has only two types of access permission modifiers (public and default)
    int modifiers = C.getmodifiers ();
  }
