Java anonymous inner class instance code explanation

This article mainly introduces the detailed explanation of the Java anonymous internal class example code. The example code is introduced in great detail, which has a certain reference value for everyone's study or work. Friends in need can refer to it

Person. java

package insof;

public class Person extends Object{
  String name;
  static int age;
  public Person() {
    this.name = "tom";
    System.out.println("执行的是构造方法");
  }
  public void test(){
    System.out.println("Person的test方法");
}

Main. java

package insof;

public class Main {

  public static void main(String[] args) {
    //匿名内部类，为Person的子类
    //该类没有类名，不能显示的调用new方法来创建对象，想要初始化属性可以用代码块

    Person p = new Person() {
      {
        super.name = "jack";
      }
      @Override
      public void test() {
        System.out.println("匿名子类");
      }
    };
    System.out.println(p.name);
    p.test();
  }
}

Output:

The construction method is executed
