Java is a programming language originally developed at Sun Microsystems (which has since merged into 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++.
Java applications are typically compiled to class file and can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible.
Java is intended to let application developers “write once, run anywhere” (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. The language is one of the most popular programming languages in use, particularly for client-server web applications. It is estimated that Java has over 10 million user
Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time.The language was initially called Oak and it went by the name Green later. Still later it was renamed Java, from Java coffee, said to be consumed in large quantities by the language’s creators.The creators aimed to implement a virtual machine and a language that had a familiar C/C++ style of notation.
Sun Microsystems released the first public implementation as Java 1.0 in 1995 which is “Write Once, Run Anywhere” (WORA) and providing no-cost run-times on popular platforms. It is secure and featuring configurable security and it allows network- and file-access restrictions.
Sun Certified Java Associate (SCJA)
SCJA certification exam provides ideal entry into an application development or a software project management career using Java technologies. This worldwide recognized certification credential validates basic knowledge of Object-Oriented Concepts, UML representation of Object-Oriented concepts, Java programming language, and general knowledge of Java Platforms and Technologies. According to Sun Microsystems, candidates for this exam include entry level Java programmers, students studying to become Java programmers, and project or program managers working with Java technology in the software development industry.
