A primitive type is predefined by the language and is named by a reserved keyword . Primitive values do not share state with other primitive values. The eight primitive data types supported by the Java programming language are: byte: The byte data type is an 8-bit signed two’s complement integer.

int , float , double , long , short , boolean and char are examples of primitive data types. You can’t invoke methods on these data types and they don’t have a high memory footprint , which is their striking difference from classes. Everything else is a class (or class-like in the case of interfaces and enums).

Primitives are passed by value, i.e. a copy of the primitive itself is passed. Whereas for objects, the copy of the reference is passed, not the object itself. Primitives are independent data types, i.e. there does not exist a hierarchy/super class for them. Whereas every Object is descendent of class “Object” .27 Ara 2011
