History of Java 2 (incl. code names)

JDK 1.1 (released on Feb 19,1997)
 Major additions included an extensive retooling of the AWT event model, inner classes added to the language, JavaBeans and JDBC.

J2SE 1.2
(Dec 8, 1998) — codename Playground.
  Major additions included reflection, a Collections framework, Java IDL (an IDL implementation for CORBA interoperability), and the integration of the Swing graphical API into the core classes. a Java Plug-in was released, and Sun's JVM was equipped with a JIT compiler for the first time.

[J2SE 1.2 and subsequent releases through J2SE 5.0 were rebranded Java 2 and the version name "J2SE" (Java 2 Platform, Standard Edition) replaced JDK to distinguish the base platform from J2EE (Java 2 Platform, Enterprise Edition) and J2ME (Java 2 Platform, Micro Edition)]

J2SE 1.3 (May 8, 2000) — codename Kestrel.
 Notable changes included the bundling of the HotSpot JVM (the HotSpot JVM was first released in April, 1999 for the J2SE 1.2 JVM), JavaSound, JNDI and JPDA.

J2SE 1.4 (Feb 6, 2002) — codename Merlin.
 This was the first release of the Java platform developed under the Java Community Process as JSR 59. Major changes included regular expressions modeled after Perl, exception chaining, an integrated XML parser and XSLT processor (JAXP), and Java Web Start.

J2SE 5.0 or 1.5
(Sep 30, 2004) — codename Tiger.
 Developed under JSR 176, Tiger added a number of significant new language features including the for-each loop, generics, autoboxing and var-args.

Java SE 6 (Dec 11, 2006) — codename Mustang --> current version
 is bundled with a database manager, facilitates the use of scripting languages (currently JavaScript using Mozilla's Rhino engine) with the JVM and has Visual Basic language support. As of this version, Sun replaced the name "J2SE" with Java SE and dropped the ".0" from the version number. Other major changes include support for pluggable annotations (JSR 269), lots of GUI improvements, including native UI enhancements to support the look and feel of Windows Vista, and improvements to the JPDA & JVM Tool Interface for better monitoring and troubleshooting

Java SE 7 — Codename Dolphin.
 The Dolphin Project started in August 2006, with release estimated in September 2010. New builds including enhancements and bug fixes are released approximately weekly.[13]
