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 after an oak tree that stood outside Gosling’s office. Later the project went by the name Green and was finally renamed Java, from Java coffee, a type of coffee from Indonesia.

This is achieved by compiling the Java language code to an intermediate representation called Java bytecode, instead of directly to architecture-specific machine code. Java bytecode instructions are analogous to machine code, but they are intended to be executed by a virtual machine written specifically for the host hardware. End-users commonly use a Java Runtime Environment installed on their device for standalone Java applications or a web browser for Java applets. Often when you develop applications for the Android or iOS platform, It is equally essential for skilled Java developers to have the skills required for the app development process.
