Let’s begin by highlighting some of the basic differences between the two:
We need to first understand exactly what a paradigm is. Technically, the set of rules, principles, and concepts used to develop a programming language is called its paradigm. Now, a probable and understandable question that comes to mind is: what is the need of a paradigm? Why can’t the same set of rules be applied to all? Every language follows a certain methodology to solve problems. The methodology depends on what the language is designed and designated to do and defines its paradigm. Understanding the paradigm of a language is important to learn its application.
Java is predominantly one of the most famous languages that use an object-oriented programming paradigm. Java is used mostly in application development and server-side development on an enterprise scale. There is a lot of data involved along with functionality, which demanded the way of programming in such a way that equal importance can be given to both data and function. Object-oriented programming is the best option to do so. It binds the data with functions and puts them together in classes to obtain the desired behaviour along with clean coding. Recently, Java has introduced a functional programming paradigm, in the form of lambdas. However, it is a still less-explored style.
SYNTAX AND FEATURES
By using an analogy, we can attempt to understand what exactly syntax and features mean for a programming language. Imagine the time when you started learning the English alphabet: you were taught exactly how ‘A’ is spelt and written. You practised writing it and the other letters singularly and gradually, with the help of syntax and paradigm laid out for the English language, today you’re able to write sentences and articulate well in the written word. In a similar manner, when you start with a programming language you need to understand certain rules of writing the code in order to build meaningful programs and software, thus making it the syntax.
Features can be seen as the abilities that are inbuilt in the language to allow you to build large scale applications utilising them.
Type checking is used to know the data type of the objects or variables in runtime.
Inheritance is a classic feature of object-oriented programming. It establishes the relation between dependent classes where the child class inherits the data or the function from the parent class. It solves the problem of an explicit definition of functions for different child classes.
To understand the concept, let’s see an example , how it is used in java:
To understand multithreading, let’s first understand the concept of a thread. A thread is an independent component of a whole application that can be executed. Java provides built-in support for multithreading which helps it execute multiple threads at the same time, thereby reducing the time of execution.
Java doesn’t support Closures. It has inheritance methods and lambda expressions instead.
Compilation and Execution
Java uses a compiler to execute its program. The source code goes through the compiler so that it can be converted into byte code, which is understandable by the machine. Once converted, the machine can execute the program.
