Introduction

Use the normalized() method of the Period class to normalize the years and months.

The method ensures that the month value stays within 0 to 11.

For example, a period of "2 years and 15 months" will be normalized to "3 years and 3 months."

Demo

import java.time.Period;

public class Main {
  public static void main(String[] args) {
    Period p1 = Period.of(2, 3, 5);
    Period p2 = Period.of(1, 15, 28);

    System.out.println("p1: " + p1);
    System.out.println("p2: " + p2);
    System.out.println("p1.plus(p2): " + p1.plus(p2));
    System.out.println("p1.plus(p2).normalized(): " + p1.plus(p2).normalized());
    System.out.println("p1.minus(p2): " + p1.minus(p2));
