As mentioned previously, the Date-Time API is fluent; therefore, each of its classes
is located in a clearly marked package.
Table 4-2
lists the packages that make up the
Date-Time API, along with brief descriptions of the classes that can be found in each.
Package
Description
java.time
The core classes of the API. These classes are used for working
with date-time data based on the ISO-8601 standard. These
classes are immutable and thread-safe.
java.time.chrono
The API for using calendar systems other than ISO-8601.
Classes for formatting date-time data.
java.time.format
Extended API that allows interpolations between date-time
classes.
java.time.temporal
Classes supporting time zone data.
java.time.zone
This chapter presents a brief overview of some commonly used date-time features.
If you will be performing significant work with dates and times, you should read the
Date-Time API documentation that is available online.
