MonthDay withDayOfMonth() Method in Java
An immutable copy of a MonthDay with the day of month altered as required is done using the method withDayOfMonth() in the MonthDay class in Java. This method requires a single parameter i.e. the day of month that is to be set in the MonthDay and it returns the MonthDay with the day of month altered as required.
A program that demonstrates this is given as follows −
Example
import java.time.*; public class Demo { public static void main(String[] args) { MonthDay md1 = MonthDay.parse("--02-22"); System.out.println("The MonthDay is: " + md1); MonthDay md2 = md1.withDayOfMonth(05); System.out.println("The MonthDay with day of month altered is: " + md2); } }
Output
The MonthDay is: --02-22 The MonthDay with day of month altered is: --02-05
Now let us understand the above program.
First, the MonthDay is displayed. Then the MonthDay with the day of month altered to 05 is displayed using the method withDayOfMonth(). A code snippet that demonstrates this is as follows −
MonthDay md1 = MonthDay.parse("--02-22"); System.out.println("The MonthDay is: " + md1); MonthDay md2 = md1.withDayOfMonth(05); System.out.println("The MonthDay with day of month altered is: " + md2);
