What is Data Types in Java?

Data is the most important thing in any programming language. Almost everything in a program revolves around data. A data type is a collection of variables that share the same properties. The concept of Data types in Java is used to categorize the variables based on their characteristics and behaviour.

Java is the most popular object-oriented programming (OOP) language for building applications that run from simple desktop applets to complex web-based enterprise solutions like Applets and servlets to standalone/networked apps like J2ME, MIDP, JSE, etc.



Data types are classified in two categories:

Primitive Data types: The primitive data types include Boolean, char, byte, short, int, long, float and double. 

Non-primitive Data types: The non-primitive data types include Classes, Interfaces, and Arrays.

The Java programming language also supports a set of data types used in defining variables, constants, fields, methods, etc. Along with their associated operators and expressions, they are known as data types in Java.

Java can also be object oriented language that means that should we would like to get any data or information member, we'll access it through item.     Java has emerged as the object-oriented programming language of choice. A number of the important theories of Java include, a Java virtual machine (JVM), which Offers the fundamental foundation for platform independence, Automated storage management Methods, such as garbage collection and Language syntax That's similar to that of the C language.  Features of Java Programming  Simple and Secure Programming Language  Architecture-neutral Portable & Robust Multithreaded Interpreted High Performance Distributed Dynamics Source: What is Core Java Programming language  & Learn Java
