From Wikipedia, the free encyclopedia

There are three types of Java Programming Language Application Programming Interfaces (APIs) :

Third-parties can freely implement any JSR specifications for an official API (even for the core API of the language), providing that they conform to the Technology Compatibility Kit (TCK) for this JSR (the TCK is a suite of tests that checks conformance of implementations for a JSR). The result of this freedom is that many official APIs have more implementations than the Sun's Reference implementation (RI).

The following is a partial list of Application Programming Interfaces (APIs) for the Java Programming Language.


Official APIs


Java Platform, Standard Edition (Java SE)

Bundled APIs (part of standard download)[1]

Name Acronym Package(s) that contain the API Description and Version History
Abstract Window Toolkit AWT java.awt First released with version 1.0.
Java Collections Framework JCF java.util Collection of standard data structures like Lists, Maps, Queues, Stacks. Included in J2SE 1.2 and later.
Swing javax.swing Included in J2SE 1.2 and later.


Drag n Drop java.awt.datatransfer
Image I/O javax.imageio
Sound javax.sound.midi
Java Database Connectivity JDBC java.sql
Java Cryptography Extension JCE javax.crypto
Included as part of J2SE 1.4 and later. Available as an optional package to versions 1.2 and 1.3.
Java Authentication and Authorization Service JAAS Included in J2SE 1.4 and later, previously released as an optional package with version 1.3.
Java Secure Socket Extension JSSE[8]
A set of packages that enable secure Internet communications. Included as part of J2SE 1.4 and later, JSSE 1.0.3 is an optional package to the Java 2 SDK, versions 1.2 and 1.3.
Java Native Interface JNI Allows Java code running in the Java virtual machine (JVM) to call and be called[1] by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages, such as C, C++ and assembly.
Java Management Extensions JMX
A technology that supplies tools for managing and monitoring applications, system objects, devices (e.g. printers) and service oriented networks. Included as part of J2SE 1.5 and later, was an optional package prior to this.
