Sorry! Did I read it correctly? 

Yes, you did. 

So, what is the logic behind this question, and how is it related to the uses of Java?


Well, many websites have only explained the uses of Java. But my friend, we(Techbiason) are not the same one. In this blog, I have detailed the topmost apps that are developed using the Java programming language.

Before discussing the thing, let me answer the question asked in the beginning. 

If you plan a space flight, then you must require the tool from


It is one of the US aerospace contractors. It supplies engineering services and products for defense industries and civilian space agencies.


JavaFX Deep Space Trajectory Explorer is a company’s product that develops using Java. It provides the trajectory designs to calculate deep space system orbits and paths. 

With the help of it, users can develop multidimensional models and views for asteroids or planet-moon systems.

This is just one of the tons of uses of Java that provides new dimensions to space flights.

Let’s find out some other astonishing uses of Java in this blog. But before that, let me give a quick overview of why Java is still useful to learn in 2021 as there are several programming languages to learn. 


Should I prefer Java over other programming languages in 2021?

Well, Java is considered to be the second most demanding programming language in 2021 and the first in the last 20 years.

Because of this, the demand for Java-skilled people takes a boost. And this leads to a better salary package and excellent job opportunities. That is why you should prefer it from a career perspective.

If we talk about it in terms of features, then Java always wins the race as it has features like platform independence, security, excellent rich APIs, and more. These make Java a great option to go with.

That is why it is always better to learn Java even in 2021.


What are the main uses of Java?

Mobile Applications

Know the official programming language for mobile applications development? Well, it is none other than Java. It is most compatible with software like Kotlin and Android. 

Now, the question is why only Java? Reason- it can run over the platform JVM (Java Virtual Machine). To execute the class files of the Android, Java uses DVK, which is Dalvik Virtual Machine.

Therefore, Java is always the better option that provides simplicity and better security with Android.

Web-based Applications

Java is always preferred by web developers for developing web applications. It offers wide support to web applications using Struts, Servlets, or JSPs. 


Because of the high security and ease of coding, developers use Java for developing a variety of applications for social security, insurance, health, and education. It is one of the best uses of java.

Gaming Applications

Java holds the support of the jMonkey engine that is the most powerful 3-D engine. This engine has unmatched abilities in terms of 3-D designing games.

But there is a drawback with the engine that is it causes an occasional latency issue. But do not worry, this issue can be solved using the new JVM version. It is one of the best uses of java.

Cloud-Based applications

Several cloud computing means offer unbeatable solutions to IT infrastructures at lower prices. Java offers features, which support applications building, which can be used in IaaS, SaaS, and PaaS developments. 


Java also supports companies to share the data with one another and in developing applications remotely. It is one of the best uses of java.

Big Data Technologies

Big data technologies such as Hadoop have become a reality just because of Java. Moreover, Scala programming languages have come into existence because of Java.

That is why I can say that it is quite clear that Java is the backbone for Big data technology developments. It is one of the best uses of java.

Scientific Applications

Java is being considered a weapon for software developers. They always prefer it for mathematical operations and scientific calculations. The programs can be designed with lightning-fast and high-security codes.


Using Java, the programs need less maintenance. The mathematical computational tools like Matlab, are being designed using Java. It is one of the best uses of java.

Desktop GUI Applications

Java has the GUI development abilities that are provided with the means like Abstract Windowing Toolkit (AWT), JavaFX, and Swing. 

AWT has pre-assembled elements such as a list, menu, and button. On the other hand, Swing is the GUI widget kit that offers advanced elements. These elements are like scroll panes, tabbed panels, trees, tables, and lists. It is one of the best uses of java.
