| | [Java|http://java.sun.com/] is actually three things: |
| | # a computer programming language |
| | # a class library |
| | # a runtime environment |
| | |
| | Applications written in Java can run on any computer platform and operating system that implements a [JRE|Java Runtime Environment]. Java is developed by the [JCP|Java Community Process] organized by [Sun|Sun Microsystems]. |
| | |
| | Java comes in three editions: |
| | # [Java Standard Edition] -- Java applications for desktops (Java SE) |
| | ** [Java language] -- The syntax for implementing Java programs |
| | ** [Java Foundation Classes] -- The Java class library (JFC) |
| | ** [Java Runtime Environment] -- Enables a computer to run a Java program (JRE) |
| | ** [Java Abstract Window Toolkit] -- A Java class library for GUI windows (AWT) |
| | ** [Java Swing] -- A Java class library for GUI windows (Swing) |
| | ** [Java Database Connectivity] -- Java classes for connecting to (relational) databases (JDBC) |
| | | ** [Java Persistence API] -- Bindings between database data and Java objects (JPA) |
| | # [Java Enterprise Edition] -- Java applications for client/server servers (Java EE) |
| | ** [Enterprise JavaBeans] -- Java objects with high quality of service (EJB) |
| | ** [Java Message Service] -- How Java applications use messaging systems (JMS) |
| | ** [J2EE Connector Architecture] -- How Java connects to external (non-Java) resources |
| | ** [Java Naming and Directory Interface] -- How Java applications access external resources (JNDI) |
| | # [Java Micro Edition] -- Java applications for portable devices (Java ME) |
| | |
| | Additional Java technologies: |
| | * [Real-Time Specification for Java] -- Java applications with predictable response times |
| | |
| | Java evolves through the work of committees that operate under the [Java Community Process] (JCP), developed by and lead by [Sun Microsystems]. The JCP committees produce specs for new Java features called [Java Specification Request]s (JSR). |
