# MonthDay withMonth() Method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a MonthDay with the month altered as required is done using the method withMonth() 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 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.withMonth(05);
System.out.println("The MonthDay with month altered is: " + md2);
}
}

## Output

The MonthDay is: --02-22
The MonthDay with month altered is: --05-22

Now let us understand the above program.

First the MonthDay is displayed. Then the MonthDay with the month altered to 5 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.withMonth(05);
System.out.println("The MonthDay with month altered is: " + md2);
