Introduction to Java
Java is an Object-Oriented Programming (OOP) language that was first released by its original developers, Sun Microsystems, back in 1995. Today the development of Java is in the hands of Oracle, following its acquisition of Sun Microsystems back in January 2010.
The Java language shares much of its syntax with the C and C++ programming languages, and is said to be fast, reliable and secure. It was developed on the WORA, or Write Once Read Anywhere, principle, which means that it can run on any platform that supports Java, including, laptops, datacentres, game consoles, supercomputers, mobile phones and more.
