Top 7 Uses Of Java In The Real World You Should Know

At present, technology is continuously going through an evolution. Java is considered one of the most commonly used programming languages without any doubt as numerous devices run on a java platform. Generally, the majority of the people seem confused about different questions regarding Java programming, such as What are the uses of Java? Why is Java so popular? Why do we use Java? In this blog, you will get an accurate answer for all your general queries regarding java programming.

What Is Java?

Sun Microsystems developed Java in 1995.  It was designed with the primary purpose of developing different programs for handheld devices and set-top boxes. Still, as time passed today, it became a popular choice for building different web application types. It is considered one of the most used high-level programming languages. 

There are various important uses of Java. Java is present everywhere, from cell phones to the Internet, laptops to datacenters, and game consoles to scientific supercomputers. Java is a reliable, fast, and secure programming language. 

Why is Java So Popular?

No doubt today, Java is one of the most popular programming languages. The main reason behind its popularity is that Java is platform-independent. If any computer has a JRE(Java Runtime Environment) connected, any java program can run on it.

There are numerous vital uses of Java. It is also noteworthy that many computer systems can be compatible with a JRE(Java Runtime Environment), such as Macintosh computers, large mainframe computers, PCs running on Windows, and Unix or Linux computers mobile phones.

So undoubtedly, we can say that Java is one of the most used programming languages as it provides numerous features and uses to its user. For many years, even many biggest companies and organizations worldwide have been using the java programming language.

Why Do We Use Java?

When it comes to comparing java programming with another programming language, it always stands alone for its functionality and security. There are various uses of Java, but the question generally arises in people’s minds: Why do we use Java? Here we have mentioned some essential reasons to use Java:-


Java provides us a cross-platform facility. Here the cross-platform means a composed java program can efficiently run on all the different platforms. But the condition is that your system must have the JVM. Once a Java program compiles successfully, then java codes are usually converted into bytecode. It is noteworthy here that this bytecode is platform-independent, and one can easily use it on any platform.


Multi-threading in java programming commonly allows different execution of more than one thread simultaneously. It will become helpful in maximizing the proper utilization of your CPU.


Scalability improves the capacity of your system by adding the system resources. One can easily achieve scalability by adding various resources like CPU, Ram, etc., in a single computer system. It plays the most important role as it maximizes productivity, manages the workload, and improves the performance of your system.


There are different uses of Java; one of the best useful things is its mechanism for mainly managing the memory. When you are using Java, you don’t need to care about your computer system’s memory. Java naturally deletes the unrequired objects when the application is not using them. It will become very helpful in improving the speed of the specific application.

With the use of Java, you can easily develop all types of desktop applications. It also provides us GUI development capability over a different medium, mainly JavaFX, AWT (Abstract Windowing Toolkit), and Swing. AWT (Abstract Windowing Toolkit) has various pre-assembled components such as buttons, menus, lists, etc. 

On the other hand, the Swing is a GUI widget toolkit that provides advanced tables, trees, tabbed panels, and lists.

Mobile Applications

One of the most preferred uses of Java programing language is in the development of Mobile applications, and it is suitable with software like Kotlin and Android Studio.

Business Applications:

The JavaEE platform is designed to help developers create multi-tiered, secure networks, reliable, scalable, and secure network applications. These different applications are mainly developed to provide accurate solutions to the problems encountered by various large-scale enterprises. 

There are serval features such as reliability and security which make business application powerful etc.
