Initially, it was named “Oak” it was renamed as “Java” in the year 1995. Java is a highly object-oriented, platform-independent and secure programming language.
One of the most important factors in the java programming language is its Bytecode conversion. Byte codes in Java are highly optimized set of instructions designed to be executed by Java Virtual Machine. JVM works as an interpreter for the byte code.
To use java programming language we require JDK (Java Development Kit) and this includes JRE (Java Runtime Environment).
