LocalDate / LocalTime / LocalDateTime

Three date-and-time types from java.time. Each one holds a different piece of the puzzle — pick the one that fits your data.

Java 8 made dates easy. Before Java 8, working with dates was painful. The java.time package introduced LocalDate, LocalTime, and LocalDateTime — clean, immutable, easy to read.

LocalDate

date only

Year, month, day. No time component. Format: YYYY-MM-DD (ISO 8601).

—

Good for: birthdays, due dates, holidays — anything that doesn't need a clock time.

LocalTime

time only

Hours, minutes, seconds, nanoseconds. No date component.

—

Good for: store closing time, daily alarm, class start time — times that repeat every day.

LocalDateTime

date + time

Both a date and a time in one object. Format: YYYY-MM-DDTHH:mm:ss.

—

Good for: timestamps, appointments, deposit times — any specific moment.

Tip: change the date or time inputs above and watch the parts update. Every getter returns exactly what its name says — no surprises.
