Jun 27, 2023 · Java provides a wide range of data types to accommodate various kinds of data and operations. In this article, I will walk you through Java's data types and explain how they work. There are two types of data types in Java – primitive data types and reference data types. Let's dive in and learn more about each.

There are 8 data types predefined in Java, known as primitive data types. Note: In addition to primitive data types, there are also referenced types (object type). The boolean data type has two possible values, either true or false. Default value: false. They are usually used for true/false conditions. public static void main(String[] args) {

There are two categories of data types in Java: 1. Primitive Data Types in Java. As the name suggests, the programming language pre-defines the primitive data types. Primitive types are the most basic data types available in Java. There are 8 primitive data types in Java: byte, char, short, int, long, float, double and boolean.

Java data types define the type and value range of the data for the different types of variables, constants, method parameters, return types, etc. The data type tells the compiler about the type of data to be stored and the required memory. To store and manipulate different types of data, all variables must have specified data types.
