Parameter: This method accepts a single mandatory parameter months which specifies the months to be set in the resultant LocalDateTime instance. The value of this months can range from 1 to 12.

Below programs illustrate the LocalDateTime.withMonth() method:
Program 1:
// Program to illustrate the withMonth() method import java.util.*; import java.time.*; public class GfG { public static void main(String[] args) { // Get the LocalDateTime instance LocalDateTime dt = LocalDateTime.now(); // Get the String representation of this LocalDateTime System.out.println( "Original LocalDateTime: " + dt.toString()); // Get a new LocalDateTime with months 5 System.out.println( "New LocalDateTime: " + dt.withMonth( 5 )); } } |
Original LocalDateTime: 2018-11-30T12:51:39.472 New LocalDateTime: 2018-05-30T12:51:39.472
Program 2:
// Program to illustrate the withMonth() method import java.util.*; import java.time.*; public class GfG { public static void main(String[] args) { // Get the LocalDateTime instance LocalDateTime dt = LocalDateTime .parse( "2015-04-06T10:15:30" ); // Get the String representation of this LocalDateTime System.out.println( "Original LocalDateTime: " + dt.toString()); // Get a new LocalDateTime with months 12 System.out.println( "New LocalDateTime: " + dt.withMonth( 12 )); } } |
Original LocalDateTime: 2015-04-06T10:15:30 New LocalDateTime: 2015-12-06T10:15:30
