JAVA使用反射机制获取Record类型的类对象判断是否是Record类型并取出所有的Component组件------JAVA

package com.example.demo;

import org.junit.Test;

import java.lang.reflect.RecordComponent;
import java.util.ArrayList;

/**
 * Unit test for simple App.

public class StudentTest {
    @Test
    public void Test01(){
//        创建Record对象
//        这里也会先执行紧凑的构造方法
        Student Rose = new Student(1001,"Rose","abc",15);
        System.out.println(Rose.toString());
        Integer age = Rose.age();
        System.out.println(age);
        String name = Rose.name();
        System.out.println(name);
        String email = Rose.email();
        System.out.println(email);
        System.out.println("哈哈");
        System.out.println(Rose.concat());
        System.out.println(Student.emailToUpperCase("Dasd"));

        ProductRecord record = new ProductRecord(1,"手机",200);
        record.print();
