What is Java Programming language? Code examples

A while back we explained what is JavaScript since a lot of users on the internet might not have a basic understanding of it. Today, we have decided to talk about Java, a popular programming language that is not the same as JavaScript.

Java Programming language

That may or may not surprise you, but it is the truth. Nevertheless, the Java programming language is very popular and we expect it to be this way for multiple years to come. This is because it is a multipurpose language that is used everywhere around the world.

We should point out that Java is considered a high-level programming language because it can be read by both humans and computers. It relies heavily on English-based commands, which is one of the reasons why it has garnered a strong following.

In the same way as English, Java comes with a set of rules that each programmer must follow. The rules in question are known as Syntax. The code is written in English for humans to understand, and then when executed, it is converted to numerals for computers to understand.

The idea behind the language is to WORA, which means, Write Once, Run Anywhere. It simply means that a compiled Java code should run on any supporting platform without the need for recompilation.

Who are the creators of Java?

Java was originally created in the 90s by a team lead by James Gosling at Sun Microsystems. For those who haven’t been keeping up with tech acquisitions, Sun Microsystems is now owned by Oracle, and that goes for Java as well.

In the early development of the language, the team was focusing on creating a tool for mobile devices, but that quickly changed when version 1.0 of Java was released for public consumption in the year 1996. These days, the language is used for a plethora of things. For example, it is used for web development, the creation of video games for mobile devices, and much more.

Over the years, Java has seen several updates, and at the time of writing, it is at version 15, which is far superior to the original release back in 1996.

Why you should use Java right now

Reliability: One of the best additions to Java over the years, is something known as object-oriented programming. It was introduced to limit errors made by programmers whenever they make mistakes, and this is something that happens even with the best of the bunch. Today, the Java language is very reliable, hence its popularity.

Security: This language was built from the ground-up with security in mind. The reason for this was because Java was originally designed for mobile devices that would eventually exchange information over a wireless network. At the time of writing, we believe Java is one of the most secure programming languages in the world.

Ease of use: For a programming language to be loved by the masses, it should be easy to use, and that is exactly what Java brings to the table. Now, the basic principles of Java have derived from C++, but they are not exactly the same since C++ can be quite complex, especially for new users. Still, despite its ease of use, we believe Python is a step above in this regard.

Works on all platforms: If developers and programmers are forced to use a single operating system to get work done, then that language they’re using is not good enough. Thankfully, we can say for certain that Java works wonderfully across multiple platforms, and this includes Windows, Linux, Mac, and more.

Java Code examples

As with most programming languages, you should begin with Hello World, and that is exactly what we’re going to do right now. The following code example is how to get it done:

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

What about comments? Yes, you can leave a comment in your code. Let us look at how to accomplish that task:

// This is a comment System.out.println("Hello World");
The overall code, then, should look like this:
public class MyClass {
public static void main(String[] args) {
// This is a comment
System.out.println("Hello World");
}
}

These are just the basics, but as time goes by, we are sure you will become an expert at coding in Java, like thousands of others.

We hope you find the post for beginners, easy to understand.
