Date and Time API

The Date and Time API in Java 8 introduced a new set of classes for handling dates, times, and time zones. It provides a more comprehensive and intuitive way to work with dates and times compared to the older java.util.Date and java.util.Calendar classes.

Java 8 Date and Time Classes

The main classes in the Date and Time API include:

• LocalDate: Represents a date without time, such as 2023-07-12.
• LocalTime: Represents a time without a date, such as 14:30:45.
• LocalDateTime: Represents a date and time, such as 2023-07-12T14:30:45.
• ZonedDateTime: Represents a date, time, and time zone.

These classes provide various methods for manipulating and formatting dates and times.

Example

Here's an example of how to use the Date and Time API:

1import java.time.LocalDate;
2import java.time.LocalTime;
3import java.time.LocalDateTime;
4
5public class Main {
6  public static void main(String[] args) {
7    LocalDate date = LocalDate.now();
8    LocalTime time = LocalTime.now();
9    LocalDateTime dateTime = LocalDateTime.now();
10
11    System.out.println("Current Date: " + date);
12    System.out.println("Current Time: " + time);
13    System.out.println("Current Date and Time: " + dateTime);
14  }
15}

This code snippet demonstrates how to get the current date, time, and date-time using the Date and Time API. The now() method is used to obtain the current date, time, or date-time instance.

The output will vary every time you run the program, but it will be similar to:

1Current Date: 2023-07-12
2Current Time: 14:30:45
3Current Date and Time: 2023-07-12T14:30:45
