1. the meaning of line 12 of code and how does it work?
2. when should we use the key word "this"? actually not in this code only I mean all the time.
package com.codegym.task.task04.task0401;
/*
This age doesn't work for me…
*/
public class Solution {
public static void main(String[] args) {
Person person = new Person();
System.out.println("Age: " + person.age);
person.adjustAge(person.age);
System.out.println("Adjusted age: " + person.age);
}
public static class Person {
public int age = 20;
public void adjustAge(int age) {
this.age = age + 20;
System.out.println("The age in adjustAge() is " + age);
}
}
}
