What is Java?
Java is a general purpose, high-level programming language developed by Sun Microsystems (now owned by Oracle). It was designed from the ground up to be a pure object-oriented language with a syntax similar to C++ but with some of the difficult aspects from C, such as memory allocation taken care of. It was also designed to be platform independent, compiling ‘byte code’ instructions for the Java Virtual Machine (JVM) that runs anywhere.
Why use Java?
As Java themselves say: write once, run anywhere.
Did you know?
Java was originally called Oak but later changed to Java (from Java coffee).
