I didnt understand this code

public class MyClass { public static void main(String[ ] args) { Person j; j = new Person("John"); j.setAge(20); celebrateBirthday(j); System.out.println(j.getAge()); } static void celebrateBirthday(Person p) { p.setAge(p.getAge() + 1); } } //Outputs "21"

Method celebratrBirthday increases age by 1. To make it more clear to understand: int newAge = p.getAge()+1; //You take person's current age p.setAge(newAge) //Then you change current age 😊
