Java is a class oriented object oriented programming language and is widely used for the development of the application which can run on any Operating System, it has strong/security features. Sun Microsystems developed it and the product later became part of Oracle when Sun Microsystems was acquired by Oracle in 2010, and the platform was first introduced in 1995. Java follows the model of writing ‘Once and Running Anywhere’ Shouldn’t be interpreted as the compiled byte code will only run on more than the particular platform that can support JVM.

Core features of Java

Object-oriented: The elements of Java are classes and a class forms an object and an object is a collection of data –field or attribute and action-method. But they are also making the code more reusable and modular and hence easier to maintain all at the same time.
Platform Independence: Java has the particular advantage of compilation for the bytecode and running through the JVM that allows the program to be not fragmented by the systems.
Robust: As in the case of exception handling, automatic garbage collection and strong types mentioned above all minimize run-time errors and makes the code more reliable.
Secure: Java has features for amplifying security like for example bytecode check, magnificence loaders.
Simple: Java language syntax is clean and easy to analyze thus readily understandable by the programmers of specific orientation.
High performance: Java is not, however, completely fast as low-level languages but it provides proper performance due to just-in-time compilation, and optimized byte code.
Multi-threaded: Java aids multithreading that promotes the ability of executing a couple of responsibilities in an application concurrently.

Explanation

This code initializes a container public class called ‘Main’ which is the program’s class. In this class, the ‘main’ method serves as the starting point of the subsequent solutions in the program. The given below method is also static and has no return type It has an argument in the form of string array ‘args’. The basic should be to output the given string, ‘Hello, World!’ to the command line using the statement System.out.println().

Summary

Java is an open, stable and relaxed language with huge environment. Being impartial to the platform, utilizing object-oriented approach, and offering strong community help, it is one of the most famous programming languages for developing organization packages, internet applications, Android apps, etc. although it has performance and, therefore, concision problems, the pros of Python normally win over cons in many cases.
