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));
    }
}

Output:

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));
    }
}

Output:

true
