Original motivation The need for platform independent language that could be embedded in various consumer electronic products like toasters and refrigerators. One of the first projects developed using Java a personal hand-held remote control named Star 7. Gosling realized that Java could be used for Internet programming. Java Technology A programming language A development environment An execution environment Development Environment Java 2 Software Development Kit Programming language Java language Execution Environment JRE Programming Language Java as the language is called the Java language, and is a language that is platform independent and object-oriented. As a programming language, Java can create all kinds of applications that you could create using any conventional programming language.
