How to use reflective API to manipulate information in java
This article mainly explains "how to use reflective API to manipulate information in java". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to use reflective API to manipulate information in java.
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 }} at this point, I believe you have a deeper understanding of "how to use reflective API to manipulate information in java".
