With the growing popularity of many languages based on simplicity and efficiency, Java is slowly losing ground. The question remains, however, is Java really going away?


Java is a programming language that was created by Sun Microsystems, and it has been the most popular for a long time.   It is a general-purpose programming language. Its design was based on C++ and it compiles to Java bytecode which can run on any platform that has a JVM (Java Virtual Machine).

It is currently used by millions of programmers in the world, this also includes big companies and universities such as Facebook, Google and NASA.  The Android operating system uses Java too; it is the most common programming language for mobile apps since its introduction in 2008. 

Nowadays, though, many other languages have surpassed Java in popularity and usage. So what about Java? Is it still used in 2021? 

In this blog post we’ll take a look at whether Java is still being used in 2021, why you may want to consider using another language instead of Java for your next project, why so many people are moving away from java already now (in 2016), some alternatives to java that are worth considering if you’re not sure which way to go but are looking for something new or different than the status quo…and more! 

Let’s get started!

What is JAVA?

As said above, Sun Microsystems introduced Java in 1995 as a key component of its Java platform, where it has become an extremely popular programming language. There is only one implementation dependency and it is class-based and object-oriented. A Java program can also run on all Java-enabled platforms without recompilation, since it is a general-purpose programming language.

Is Java worth learning in 2021?

So should you learn Java? The answer depends on what your long-term goals are regarding margin. That being said, there is. In fact, if you’re planning to go for an Android development career in the next few years, then you’ll need to learn Java anyway. 

In 2021, most people would say that Java is worth learning. They might say this because they feel like it’s a valuable skill to have for a programmer or developer. It may also be worth learning if you’re someone who uses social media applications like Facebook and Google+ since Java is one of the languages used for these types of apps.   And let’s not forget that the Android operating system uses Java as well, so if you’re looking to get into mobile app development, you’ll need knowledge of various programming languages. 

Today, Java may not be as popular with mobile app development when compared to more recent programming languages such as Swift (which was developed by Apple), but there are still plenty of areas where it is used.

Another reason why developers love Java so much is that they can create applications very quickly compared to other languages and platforms out there right now. With the help of the Java Development Kit (JDK), you can begin developing an app with ease. And since Android uses Java as one of its main programming languages, you know that it will work perfectly when ported over to this operating system.

Should I choose Java for my next project?

I would recommend using Java for your next project. Java is easy to learn and has a lot of free tutorials available online. It’s also one of the most popular programming languages in the world with many jobs requiring knowledge of it. And because it is an object-oriented programming language, you’ll be able to reuse code and use inheritance as needed.

What is Java used for in 2021?

As Java is valued for its extensive usage capabilities and will help you get a lot done, it is important to see how to examples of implementation:

Mobile development

Mobile development with the Java programming language is easier now than ever before. There are many libraries that have been made available for most of the major mobile operating systems to make life easier. With Java, you can easily create a cross-platform mobile app with just one codebase.

Big Data

Java has been popular in the area of big data with the emergence of the cloud. Big data is a term that refers to large volumes of diverse, unstructured and oftentimes complicated information which must be analyzed for insights that can be used to provide greater value or service. Java is great for big data because it is designed for 2 major things:

  1. It’s scalable so it can spread out over as many CPUs as you have without adding more lines of code and
  2. Java was designed to be multipurpose which is perfect for big data as this type of work usually results in various types of analysis such as clustering or summarization.

AI-Development

Java is becoming increasingly popular in the AI development field. There are a lot of reasons for this. One of the biggest reasons is that Java integrates well with machine learning, which most AI developments use. Another reason is that it’s an object-oriented language that allows you to develop applications quicker and easier than other languages. Lastly, Java makes it a little bit easier to debug your code so you can find and fix errors before running the application.

Remote Access with java

Remote access has been around for a while but it has been enhanced with Java. With Java, you are able to do a lot more and you can do it faster than before. You can use remote access if you don’t have a computer on your desk, want to work from home, in the office, or anywhere else where there is a Wi-Fi connection. Remote applications can be used as well as remote browsers and each one of these has been enhanced with Java.

Web-based applications of Java

Java has expanded its reach in recent years to include web-based applications. There are a number of reasons for this, but among them are the heavy integration with JavaScript and Java object-oriented nature which can lead to quicker development times.

A major reason for the expansion is that big companies like Google and Yahoo offer a range of SDKs (Software Development Kits) for Java which enables developers to easily integrate Java into any web application, making it versatile in terms of who can use it. It also offers an alternative to PHP or other languages.

Embedded System

Embedded systems are a great thing when it comes to using Java.  There’s a lot of different ways that AI developers can use Java to make their lives easier. One of those reasons is that Java integrates well with machine learning which most AI developments use. Another reason is that it’s an object-oriented language that allows you to develop applications quicker and easier than other languages.

Final Verdict: Is Java a dying technology?

Java is not a dying technology. Java has been increasing in popularity over the last few years, as seen in the newest TIOBE index. This is due to Java’s popularity in the area of mobile development and big data. There are many libraries that have been made available for most of the major mobile operating systems to make life easier.  With Java, you can easily create a cross-platform mobile app with just one codebase.
