Data Types in Java With Example 

What is Data Types?

• Data types are used to represent types of variables and expressions.
• Data types are used to represent how much memory is allocated for variables.
• Data types are used to specify the range value of the variable. 

Data types in Java

Syntax of Data Types

The basic syntax of the data type is as follows,

Data types   name of variable = value /literal;

Eg.  int a=10;

int  ->   Data Type

a    ->   Variable name

=    ->  Assignment

10  ->   Constant Value

;    ->   Statement terminator 

Types of Data Types in Java

Data types are divided into two sub-part

• primitive data type
• Non-Primitive data type

Primitive data type in Java

In Java primitive data types are used to specify the size and type of variable of value.

There are 8 Primitive data types in Java 

• Byte
• Short
• Int
• Long
• Float
• Double
• Char
• boolean

Non-Primitive data type in Java

In Java Non-primitive data types are also known as reference types because Non-primitive data types refer to objects.

Examples of non-primitive data types

• Strings
•  Arrays
• Classes, 
• Interface etc.

The important point to remember about Non- primitive data type

• In Java a non-primitive data type is not pre-define it is created by the Java programmer except string data type
• In Java, programmers used non-primitive data types to call the method to perform some creation actions.
• In Java, a non-primitive data type can be null.
• In Java, a non-primitive data type starts with Upper Case

Byte  Data Type

Float Data Type

Double Data Type

Char Data Type
