What is Java?
Java is a popular programming language, created in 1995.
It is owned by Oracle, and more than 3 billion devices run Java.
It is used for:
- Mobile applications (specially Android apps)
- Desktop applications
- Web applications
- Web servers and application servers
- Games
- Database connection and much more
Why Use Java?
Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.) and thus platform independent.
- It is one of the most popular programming language in the world
- It is easy to learn and simple to use
- It is open-source and free
- It is secure, fast and powerful
- It has a huge community support (tens of millions of developers)
- Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs
- As Java is close to C++ and C#, it makes it easy for programmers to switch to Java or vice versa
How to get started
I would surely advice you to first downloading the Java Development Kit(jdk) from the official Oracle website here dependent on your system whether linux, Macos or Windows.
Next, I would download an Integrated Development Environment(IDE). They are a tone of IDE's out there but I would surely recommend Intellij IDE made by JetBrains due to a number of reasons here and there, you can download the Intellij community edition from here.

// a small Java program
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
