Primitive and Non-Primitive Data Types in Java

Java Institute in Chennai

Data types are essential in Java because they define what information can be manipulated and saved. Simple value representation is based on primitive data types, which include characters, booleans, integers, and floating-point numbers. This Blog reveals How To Understand Primitive and Non-Primitive Data Types in Java, and the Java Institute in Chennai offered by FITA Academy can aid individuals who wish to comprehend more about it. Types of data types in java are briefly explained below.

Java Data Types

Java categorizes data types into two groups:

Primitive Data Types

Primitive data types in Java determine value types and measures for variables. They cannot be further broken down into more basic forms of data because they are the fundamentals of manipulating data. Types of primitive data types are given below:

Type of Boolean: Boolean

They can be used in conditional statements to return True or False to determine whether two values are equal or not. Programmers usually track true or false conditions using it as a flag variable.

Character Category: Char

To store a single character, use the char data type. It keeps track of capital and lowercase characters, which must be encircled in single quotes.

Integer Type 

No fractional or decimal places are present in an integer number stored in an integer type. Java has four types of integers: byte, short, int, and long.

Float type

Expressions with fractional precision employ floating-point technology. There are two varieties: double and float.

  • Float

To maintain decimal accuracy, the significances are stored in a floating-point data format.

  • Twice 

Float and the double data type are comparable. In decimal accuracy, the difference between the two is that it is double twice the float. 

Non-Primitive Data Types 


An array contains only the same kind of elements. The array name, which is used for declaration, is an object in Java and the reference value that holds the base address of the continuous position of an array’s elements. Array data type can be received by completing a Java Online Course.


Although defined what is data type in Java, a string is not primitive. Double quotations surround string literals.


An object is constructed from a user-defined data type called a class. It explains the collection of qualities conveyed by all items of the same class. It has properties and methods that reflect how an object behaves. When a class is created, the corresponding object is created.


Similar to a class, an interface is declared. The main distinction is that ideational methods are absent from the interface; instead, they are present by default.


An enum has methods and attributes just like a class does. Developers cannot use enums to build objects or extend other classes. Nonetheless, interfaces can be implemented by the enum.


The foundation of programming languages is data types. Understanding Java data types is a prerequisite to understanding more complex Java concepts. You can construct any application or software, even simple ones, with the aid of an understanding of data types. You can get help learning Java from several coaching centres. Similar to the top Java Training Institutes in Bangalore, which offer certification along with this training and promise placement rates of 100%.
