Data types are essential in Java because they define the types of information that can be stored and manipulated. Integers, floating-point numbers, characters, and booleans are primitive data types that are the foundation for encoding simple values. Learn more about the Data Types by enrolling in the Java Course in Chennai at FITA Academy. This Blog will discuss How To Understand Primitive And Non-Primitive Data Types In Java.
Data Types in Java
Primitive Data Types
It specifies the size and kind of values for variables. They are the fundamental building elements of data manipulation and cannot be subdivided further.
Boolean
True or False can be stored in a boolean data type. They can determine whether two values are equal. Programmers commonly use it as a flag variable to track true or false conditions.
Character
A single character is stored in this type of data. It saves lowercase and uppercase characters that single quotes must surround. The char data type in Java supports Unicode characters and allows for many languages. You can learn char data type by completing a comprehensive Java online course.
Integer Type
An integer type holds a whole number without any fractional or decimal points. There are four integer types in Java.
Float Type
A floating-point expression is one with a fractional precision. It comes in two varieties: float and double.
Float: It is a form of floating-point data that stores values with decimal accuracy. It isn’t used for precise data like cash or study.
Double: These types are similar to float data types. It is used for decimal values, like float, and should not be used for precise quantities.
Non-Primary Data Types
Instances of objects are referred to as non-primitive types of information or reference data types. They are unable to store the contents of a variable in memory immediately. Non-primitive data types are all the same size.
Array
In Java, it is an object, and the array title (used for creation) is an identifier value that contains the base address of the array’s continuous position.
String
A sequence or array containing characters is stored in the String data type. Double quotes surround string literals.
Class
It is a data type defined by the user from which objects are generated. It defines the set of methods shared by all objects of the exact type.
Interface
It is declared in the same way that a class is. The critical difference is that the interface includes abstract methods by default, whereas they do not.
