Period minusMonths() method in Java
An immutable copy of the Period object where some months are subtracted from it can be obtained using the minusMonths() method in the Period class in Java. This method requires a single parameter i.e. the number of months to be subtracted and it returns the Period object with the subtracted months.
A program that demonstrates this is given as follows
Example
import 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 = p1.minusMonths(2);
System.out.println("The Period after subtracting 2 months is: " + p2);
}
}Output
The Period is: P5Y7M15D The Period after subtracting 2 months is: P5Y5M15D
Now let us understand the above program.
First the current Period is displayed. Then an immutable copy of the Period where 2 months are subtracted is obtained using the minusMonths() method and this is displayed. A code snippet that demonstrates this is as follows:
String period = "P5Y7M15D";
Period p1 = Period.parse(period);
System.out.println("The Period is: " + p1);
Period p2 = p1.minusMonths(2);
System.out.println("The Period after subtracting 2 months is: " + p2);
