Java Time

Java Time is the modern date and time API introduced in Java 8 as part of the java.time package. It provides a comprehensive set of classes for handling dates, times, time zones, durations, and periods in a more intuitive and thread-safe way compared to the legacy java.util.Date and Calendar classes. The API is designed to be immutable, fluent, and based on the ISO-8601 calendar system.

Also known as: java.time, JSR-310, Java 8 Date/Time API, Java Date and Time API, Java 8 Time

Why learn Java Time?

Developers should learn Java Time for any application requiring date and time manipulation, such as scheduling systems, financial applications, or logging, as it offers better clarity, reduced errors, and improved performance. It is essential for modern Java development, especially when working with internationalization, time zone conversions, or complex date calculations, and is widely used in frameworks like Spring Boot and JPA.
