JAVA TUTORIAL : 4 (DATA TYPES AND LITERALS)

Data types is a classification in programming languages which indicates the type of value a variable can store. Different types of values are there & different operations are there for every data type. 

Data types in Java are classified into two types:

Primitive—which include Integer, Character, Boolean, and Floating Point.

Non-primitive—which include Classes, Interfaces, and Arrays.

Non-Primitive data types are basically defined by the programmers and primitive ones are already defined in the programming languages like Java.

For Example:

Integer nonPrimitive = new Integer(50);

A Literal is the source code representation of a fixed value; literals are represented directly in your code without requiring computation.

 For Example:

 Boolean isPrimitive =  true;

In above line of code "Boolean" is a primitive data type and "true" is a Literal.
