How many primitive data types are there in Java?

Java includes a set of fundamental data types known as primitive data types. These data types are the essential components for storing and managing various kinds of data, including numbers, characters, and boolean values. Java encompasses a total of eight primitive data types, and this article aims to provide an in-depth explanation of each type in a simplified manner. 1.      byte: The byte data type is designed for storing small integer values, with a range spanning from -128 to 127. 2.      short: Slightly more accommodating than byte , the short data type can be employed for storing relatively larger integer values, ranging from -32,768 to 32,767. 3.      int: Among the most commonly used primitive data types, int can hold larger integer values, with a range extending to approximately -2 billion to 2 billion. 4.      long: When dealing with very large integer values, the long data t...
