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, much more!
Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its original features from SmallTalk, with a syntax similar to C and C++, but it has fewer low-level facilities than either of them.

The latest version is Java 11, released on September 25, 2018, which follows Java 10 after only six months, being in line with the new release schedule. Java 8 is still supported but there will be no more security updates for Java 9.and more than 3 billion devices run Java.

There were five primary goals in the creation of the Java language:
  1. It must be "simple, object-oriented, and familiar".
  2. It must be "robust and secure".
  3. It must be "architecture-neutral and portable".
  4. It must execute with "high performance".
  5. It must be "interpreted, threaded, and dynamic"
Why Use Java?
  • Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
  • 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 Syntax

public class MyClass {
# public static void main(String[] args) {
#System.out.println("Hello World");
Every line of code that runs in Java must be inside a class. In our example, we named the class MyClass. A class should always start with an uppercase first letter.
Note: Java is case-sensitive: "Hello" and "hello" has different meaning.
