Welcome to the Java programming world!

Humans can write instructions that a computer can follow using programming languages. Computers coordinate the applications and systems that run the modern world with precise instructions.

The Java programming language was first released in 1995 by Sun Microsystems . Java is well-known for its ease of use, portability, security, and reliability. Despite the fact that it was first released over two decades ago, Java is still one of the most widely used programming languages today.

The Java Virtual Machine, which ensures that the same Java code can run on different operating systems and platforms, is one of the reasons why people love Java. “Write once, run anywhere,” was Sun Microsystems’ slogan for Java.

Syntax, or the specific instructions that Java understands, makes up programming languages. We create programs by writing syntax in files, which are then executed by the computer to complete the task.

Let’s begin with a programming language’s universal greeting. We’ll look at the syntax in the next exercises:

public class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello World!");

//Output: Hello World!
