Introduction to Java

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