Java was started as a project called “Oak” by James Gosling in June 1991. Gosling’s goals were to implement a virtual machine and language that had a familiar C-like notation but with greater uniformity and simplicity than C/C++. The first public implementation was Java 1.0 in 1995.it made the promise of “Write Once, Run Anywhere”, with free runtimes on popular platforms.It was fairly secure and its security was configurable, allowing for network and file access to be limited. The major web browsers soon incorporated it into their standard configurations in a secure “applet” configuration.popular quickly. A new version for large and small platforms(J2EE and J2ME) soon were designed with the advent of “Java2”.Sun has not announced any plans for a “Java 3”.In 1997, sun approached the ISO/IEC JTC1 standards body and later the Ecma International to formalize Java, but it soon withdrew from the process.Java remains a proprietary de facto standard that is controlled through the Java Community Process. Sun makes most of its Java implementations available without charge, with revenue being generated by specialized products such as the Java Enterprise System. Sun distinguishes between its Software Development Kit(SDK) and Java Runtime Environment(JRE) which is a subset of the SDK, the primary distinction being that in the JRE the compiler is not present.
