Date and Time

Code

import java.time.*;
import java.time.format.*;

// Current date-time
LocalDate date = LocalDate.now();
LocalTime time = LocalTime.now();
LocalDateTime dateTime = LocalDateTime.now();
ZonedDateTime zoned = ZonedDateTime.now();

// Create specific date
LocalDate birthday = LocalDate.of(2000, 1, 1);

// Date arithmetic
LocalDate nextWeek = date.plusWeeks(1);
LocalDate lastMonth = date.minusMonths(1);

// Format
String formatted = dateTime.format(
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));

// Parse
LocalDate parsed = LocalDate.parse("2024-01-15");

// Duration and Period
Duration duration = Duration.between(time, LocalTime.MIDNIGHT);
Period period = Period.between(birthday, date);

Explanation

The java.time package provides immutable, thread-safe date-time classes.
