The record class

The record class was added to the SDK in Java 16. It was a long-awaited Java feature. It allows you to avoid writing boilerplate code in a case when you need an immutable class (with getters only), which looks similar to the following Person class (see the Record class in the ch02_oop folder):

final class Person {

    private int age;

    private String name;

    public Person(int age, String name) {

        this.age = age;

        this.name = name;

    }

    public int age() { return age; }

    public String name() { return name; }

    @Override

    public boolean equals(Object o) {
