Chapter 9. Java Platform, Standard Edition

The Java Platform, Standard Edition (SE), includes the Java Runtime Environment (JRE) and its encompassing Java Development Kit (JDK; see Chapter 10), the Java Programming Language, Java Virtual Machines (JVMs), tools/utilities, and the Java SE API libraries. A variety of platforms are available including Windows, macOS, Linux, and Solaris.

Common Java SE API Libraries

Java SE 9 API standard libraries are provided within packages (and modules). Each package is made up of classes and/or interfaces. An abbreviated list of commonly used packages is represented here to demonstrate the capabilities of the API. They are listed outside of the module ordering in JDK 9.

Java SE provides the JavaFX runtime libraries from Java SE 7 update 6 and JavaFX 2.2 onwards. Jav⁠aFX has replaced the Swing API as the primary client UI library for Java SE.
