I want to get the largest date today onwards. How to get this using another way.292278994 this year cant save my DB I need only 4 characters for the year.

Solution

To get the boundary dates of the current year, you can use the java.time API and set the month/day values to january 1st and december 31st respectively:

    LocalDateTime now = LocalDateTime.now();
    LocalDateTime startOfYear = now.withMonth(1).withDayOfMonth(1).withHour(0).withMinute(0).withSecond(0).withNano(0);
    LocalDateTime endOfYear = now.withMonth(12).withDayOfMonth(31).withHour(23).withMinute(59).withSecond(59).withNano(999999999);
    System.out.println(startOfYear);
    System.out.println(endOfYear);

Output:

2022-01-01T00:00
2022-12-31T23:59:59.999999999
