This article introduces the relevant knowledge of "what is the process of using java reflection". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Getting the class object you want to operate is the core of reflection, and we can call the methods of the class arbitrarily through the class object.

2. Calling the method of the class class is the use phase of reflection.

3. Use reflection API to manipulate this information.

Example

Class Worker {/ * two public construction methods * / public Worker () {count++;} public Worker (String name) {super (); this.name = name;} / * two private construction methods * / private Worker (String name,int age) {super (); this.name = name;this.age = age;} private Worker (int age) {super (); this.age = age;} / * two private attributes * / private String name;private int age;/* one public attribute * / public String parents / * one private static attribute * / private static int count;/* one public static attribute * / public static String address;/* two public methods * / public String getName () {return name;} public void setName (String name) {this.name = name;} / * two private methods * / private int getAge () {return age;} private void setAge (int age) {this.age = age;} / * two public static methods * / public static void printAddress (String address) {System.out.println ("printAddress===" + address) } public static void printAddress () {System.out.println ("printAddress===default");} / * two private static methods * / private static void printlnCount (int count) {System.out.println ("printCount===" + count);} private static void printlnCount () {System.out.println ("printCount===000");} @ Overridepublic String toString () {return "this is a Worker instance: name=" + name+ ", age=" + age;}} "what is the use of java reflection?"
