What Are Primitive Data Types In Java ?

All datatypes in small letters (int, byte, char...) are primitive datatypes which means that they are not objects (Integer, Byte...).

Objects use more resources but offer a set of methods to manipulate them.

In order to reduce the resources, primitive datatypes were introduced to Java.

This step was one that made Java less object oriented. In a fully object oriented language, EVERYTHING is an object ,even variables and even if that means to produce a lot of overhead.

Fortunately, each primitive Java datatype has its object representation. So you as a programmer can decide whether you want to save resources (use primitives) or go object oriented (use object wrappers).
