The number of months for a particular Period can be obtained using the getMonths() method in the Period class in Java. This method requires no parameters and it returns the number of months in the Period.A program that demonstrates this is given as followsExample Live Demoimport java.time.Period; public class Demo {    public static void main(String[] args) {       String period = "P5Y7M15D";       Period p = Period.parse(period);       System.out.println("The Period is: " + p);       System.out.println("The number of months are: " + p.getMonths());    } }OutputThe Period is: P5Y7M15D The number of ...

An immutable copy of the Period object where some years are subtracted from it can be obtained using the minusYears() method in the Period class in Java. This method requires a single parameter i.e. the number of years to be subtracted and it returns the Period object with the subtracted years.A program that demonstrates this is given as followsExample Live Demoimport java.time.Period; public class Demo {    public static void main(String[] args) {       String period = "P5Y7M15D";       Period p1 = Period.parse(period);       System.out.println("The Period is: " + p1);       Period p2 ...
