Describe the different types of data types used in Java

Java has several different types of data types. They are divided into two categories: primitive data types and non-primitive data types.

1. Primitive Data Types: These are the most basic data types in Java. They include:

   • Integer: This type is used to store integer values. It can be further classified into byte (8 bit), short (16 bit), int (32 bit), and long (64 bit).

   • Floating-Point: This type is used to store decimal numbers. It can be further classified into float (32 bit) and double (64 bit).

   • Character: This type is used to store a single character. It is represented by char.

   • Boolean: This type is used to store either true or false.

2. Non-Primitive Data Types: These are also known as reference data types because they refer to objects. They include:

   • String: This type is used to store a sequence of characters.

   • Arrays: This type is used to store a fixed number of values of the same type.

   • Classes: This type is used to store objects of a class.

   • Interface: This type is used to implement interfaces in Java.

Each of these data types has a different use and can be used in different scenarios depending on the requirements of the program.
