Download Java Runtime Environment 8.0 build 45
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2015, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licences. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets).
Major release versions of Java, along with their release dates:
- JDK 1.0 (January 21, 1996)

- J2SE 1.2 (December 8, 1998)
- J2SE 1.3 (May 8, 2000)
- J2SE 1.4 (February 6, 2002)
- J2SE 5.0 (September 30, 2004)
- Java SE 6 (December 11, 2006)
- Java SE 7 (July 28, 2011)

Google and Android, Inc. have chosen to use Java as a key pillar in the creation of the Android operating system, an open source mobile operating system. Although the Android operating system, built on the Linux kernel, was written largely in C, the Android SDK uses the Java language as the basis for Android applications. However, Android does not use the Java virtual machine, instead using Java bytecode as an intermediate step and ultimately targeting Android's own Dalvik virtual machine.
Android also does not provide the full Java SE standard library, although the Android class library does include an independent implementation of a large subset of it. This led to a legal dispute between Oracle and Google. On May 7, 2012, a San Francisco jury found that if APIs could be copyrighted, then Google had infringed Oracle's copyrights by the use of Java in Android devices. District Judge William Haskell Alsup ruled on May 31, 2012, that APIs cannot be copyrighted, but this was reversed by the Ninth Circuit Court of Appeals in May 2014.
The Java Runtime Environment (JRE) released by Oracle is a software distribution containing a stand-alone Java VM (HotSpot), browser plugin, Java standard libraries and a configuration tool. It is the most common Java environment installed on Windows computers.
Oracle's JRE is installed on a large number of computers. Since any web page the user visits may run Java applets, Java provides an easily accessible attack surface to malicious web sites that the user visits. Kaspersky Labs reports that the Java web browser plugin is the method of choice for computer criminals. Java exploits are included in many exploit packs that hackers deploy onto hacked web sites.
In the past, end users were often using an out-of-date version of JRE which was vulnerable to many known attacks. This lead to the widely shared belief between users that Java is inherently insecure. Since Java 1.7, Oracle's JRE for Windows includes automatic update functionality.
