Java History Features Pdf Java Programming Language Programming 1.1 introduction to java and brief history: java is a general purpose, class based, and robust, secure, safe, object oriented programming language. it was developed by sun micro system in 1991 by james gosling its name was oak. in 1995 its name has been changed to java because of some legal issues. First java compiler translates source code into what is known as bytecode instructions, bytecodes are not machine instructions and therefore, in the second stage, java interpreter generates machine code that can be directly executed by the machine that is running the java program. This document summarizes the version history of java. it discusses the original release of java 1.0 in 1995 and subsequent updates including java 1.1, 1.2, and 2.0. it provides a table listing over 30 core api packages available in java 2, showing classes and interfaces added in each version.

(r20a0552) java programming course objectives: to create java programs that leverage the object oriented features of the java language, such as encapsulation, inheritance and polymorphism; use data types, arrays and strings; implement error handling techniques using exception handling,. The java compiler translates java source code into an intermediate code known as byte code which executes on a special type of machine. this machine is called java virtual machine and exists only inside the computer memory.
