Here is code using YearMonth Class.

YearMonth is a final class in java.time package, introduced in Java 8.

public static void main(String[] args) {

    int year = 2021;  // you can pass any value of year Like 2020,2021...
    int month = 6;   // you can pass any value of month Like 1,2,3...
    YearMonth yearMonth = YearMonth.of( year, month );  
    LocalDate firstOfMonth = yearMonth.atDay( 1 );
    LocalDate lastOfMonth = yearMonth.atEndOfMonth();

    System.out.println(firstOfMonth);
    System.out.println(lastOfMonth);
}
