Below programs illustrate the YearMonth.isBefore() method in Java:
Program 1:
// Program to illustrate the isBefore() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // Create first Year object        YearMonth yearMonth1            = YearMonth.of(2018, 3);          // Create second Year object        YearMonth yearMonth2            = YearMonth.of(1997, 4);          // Check if this year-month object's value is        // before the specified Year-month or not        System.out.println(yearMonth1                               .isBefore(yearMonth2));    }} |
false
Program 2:
// Program to illustrate the isBefore() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // Create first Year object        YearMonth yearMonth1            = YearMonth.of(1997, 3);          // Create second Year object        YearMonth yearMonth2            = YearMonth.of(2018, 4);          // Check if this year-month object's value is        // before the specified Year-month or not        System.out.println(yearMonth1                               .isBefore(yearMonth2));    }} |
true
