What is Java

Java is a high-level programming language used to create software and applications.

In other words, "Java is an object-oriented programming language used to build mobile and web applications."

Java was developed by James Gosling in 1995, which is why he is also known as the ‘Father of Java’.

Java is an open-source language, which means anyone can use it for free.

Features of Java:

Simple: It is easy to understand and write. If you understand the basic concepts of OOPs, nothing can stop you from mastering Java.

Secure: It is famous for its security features. You can develop virus-free, tamper-free system software. It uses public-key encryption for authentication techniques.

Architectural-neutral: The code generated by the compiler is bytecode, which you can run anywhere, on any operating system and processor. That’s why it is called Architectural Neutral. The Java Virtual Machine (JVM) is required for this, which is present in all systems.

Portable: Because it is platform-independent, it is also portable. Both the Java language and compiler are written in ANSI C.

Robust: Programs written in it are strong. Not strong like iron, but strong in the sense that they are free of errors when the program is run. This is because it uses compile-time and run-time error checking mechanisms.

Multi-threaded: This feature allows you to write programs that can perform multiple tasks at once. This means you can have one application that performs all tasks.

High Performance: Thanks to Just-In-Time compilers, Java’s performance is quite good.

Distributed: Because of this nature, it maintains its prominence in the distributed environment of the Internet.

Dynamic: It is a dynamic language. It can adapt to any environment.
