Introduction to Java

Java is one of the most important and widely used computer languages. 

Java is a high level, robust, object-oriented and a secure and stable programming language but it is not a pure object-oriented language because it supports primitive data types like int, char etc.

Java is a platform-independent language because it has runtime environment i.e JRE and API. Here platform means a hardware or software environment in which anapplication runs.

Java codes are compiled into byte code or machine-independent code. This byte code is run on JVM (Java Virtual Machine).
