Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform. Have no Internet connection at all, you should download an offline version.The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library. Can develop all Java applications like Java SE, Java FX, web, EJB and mobile applications.Mac OS X users can update to the latest Java through the Software Update.

Internationalization and Unicode support originating from Taligent The release on Decemand subsequent releases through J2SE 5.0 were rebranded retrospectively 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). JIT (Just In Time) compiler on Microsoft Windows platforms, produced for JavaSoft by Symantec![]() HotSpot JVM included (the HotSpot JVM was first released in April 1999 for the J2SE 1.2 JVM) Java IDL, an IDL implementation for CORBA interoperabilityThe most notable changes in the release were: Sun's JVM was equipped with a JIT compiler for the first time Free driver download for canoscan 8800f macRegular expressions modeled after Perl regular expressions Java Platform Debugger Architecture (JPDA)The Februrelease was the first release of the Java platform developed under the Java Community Process as JSR 59. Java Naming and Directory Interface (JNDI) included in core libraries (previously available as an extension) Integrated security and cryptography extensions ( JCE, JSSE, JAAS) Integrated XML parser and XSLT processor ( JAXP) (specified in JSR 5 and JSR 63) Image I/O API for reading and writing images in formats like JPEG and PNG Non-blocking I/O (Java) (named NIO) (specified in JSR 51) Internet Protocol version 6 ( IPv6) support Updates were available to paid Oracle customers until May 2015.
