MonthDay with() Method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a MonthDay with the month of the year altered as required is done using the method with() in the MonthDay class in Java. This method requires a single parameter i.e. the month that is to be set in the MonthDay and it returns the MonthDay with the month of the year altered as required.

A program that demonstrates this is given as follows −

Example

 Live Demo

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.with(Month.AUGUST);
      System.out.println("The MonthDay with month of year altered is: " + md2);
   }
}

Output

The MonthDay is: --02-22
The MonthDay with month of year altered is: --08-22

Now let us understand the above program.

First the MonthDay is displayed. Then the MonthDay with the month of year altered to AUGUST is displayed using the method withMonth(). 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.with(Month.AUGUST);
System.out.println("The MonthDay with month of year altered is: " + md2);
