Below programs illustrate the withMonth() method:
Program 1:
// Java program to demonstrate // YearMonth.withMonth() method import java.time.*; import java.time.temporal.*; public class GFG { public static void main(String[] args) { // create a YearMonth object YearMonth yr = YearMonth.of( 2019 , 12 ); // print instance System.out.println( "YearMonth before" + " applying method: " + yr); // apply withMonth method of YearMonth class YearMonth updatedlocal = yr.withMonth( 1 ); // print instance System.out.println( "YearMonth after" + " applying method: " + updatedlocal); } } |
YearMonth before applying method: 2019-12 YearMonth after applying method: 2019-01
Program 2:
// Java program to demonstrate // YearMonth.withMonth() method import java.time.*; import java.time.temporal.*; public class GFG { public static void main(String[] args) { // create a YearMonth object YearMonth yr = YearMonth.of( 2022 , 7 ); // print instance System.out.println( "YearMonth before" + " applying method: " + yr); // apply withMonth method of YearMonth class YearMonth updatedlocal = yr.withMonth( 12 ); // print instance System.out.println( "YearMonth after" + " applying method: " + updatedlocal); } } |
YearMonth before applying method: 2022-07 YearMonth after applying method: 2022-12
