The History of Java

The History of JAVA

          Java is related to C++, which is a direct descendant of C. Much of the character of java is inherited from these two languages. From C, Java derives its Syntax. Many of java's Object-Oriented features were influenced by C++. In fact, several of Java's defining characteristics come from or are responses to its predecessors.

The Creation of JAVA

       Java was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank and Mike Sheridan at Sun Micro Systems, Inc in 1991. It took 18 moths to develop the first working version. The language was initially called "Oak" but was renamed "Java" in 1995. Between the initial  implementation of Oak in the fall of 1992 and the public announcement of java in the spring of 1995, many more people contributed ti the design and evolution of the language. Bill joy, Arthur van Hoff, Jonathan Payne, Frank Yellin and Tim Lindholm were key contributors to the maturing of the original prototype.

Java's Magic: The Bytecode

     The key that allows Java to solve both the security and the portability problems just described in that the output of a Java compiler is not executable code. Rather it is bytecode. Bytecode is a highly optimized set of instructions designed to be executed by the Java run-time system, which is called Java Virtual Machine(JVM). In essence the original JVM was designed as an interpreted for bytecode.
