Java programming paradigms

What are programming paradigms? Since software development began, there have been different approaches to designing programing languages. For each programming language, we have a set of concepts, principles, and rules. Such a set of concepts, principles, and rules is called a programming paradigm. In theory, languages are considered to fall under one paradigm only, but, in practice, programming paradigms are mostly combined in one language. 

In the following section, we will highlight the programming paradigms on which Java programming language is based, along with the major concepts that describe these paradigms. These are imperative, object-oriented, declarative, and functional programming.
