This blog will examine the Top Applications of Java in the real World.


Java Applications In Real World

1. Desktop GUI Applications

 Java is a potent language for creating desktop applications, and AWT, Swing, and JavaFX all support it. Although AWT (Abstract Window Toolkit) incorporates Windows UI features, it is not entirely Java-based and is used to create desktop application user interfaces. Swing, on the other hand, is a Java-based framework that enables the development of exclusively Java-based desktop applications.


The graphical user interface of JavaFX, a cutting-edge method for creating desktop applications that deviate dramatically from AWT and Swing, is modern. Developers can make any desktop application using these packages and frameworks. Drag-and-drop functionalities are also available in the NetBeans IDE, speeding up the development of user interfaces. Developers can use the software ScenBuilder to create the user interface of an application when working with JavaFX.


2. Mobile Applications

A cross-platform development environment called Java creates apps for smartphones and other devices with small screens. According to a survey, Java is the second most preferred language for developing mobile applications. Java has created popular mobile applications like Netflix, Twitter, Spotify, etc.

Java is a platform used to develop mobile applications because:

  • Helps in writing fundamental code
  • Cross-platform functionality
  • Excellent Kotlin compatibility
  • Maximum safety

3.  Scientific Application

Java’s robustness and security features make it a popular choice for designing scientific applications. Several scientific programmes are built on Java technology, including MATLAB, whose front-end and back-end are based on Java.

Java offers Struts, JSP, and Servlets on the front end, while core Java can be utilized in Servlets for the back end. Java is utilised by applications connected to research, science, and medicine due to its robust mathematical calculations that generate consistent results across platforms.


4. Enterprise Applications

Because of its robust features and ability to satisfy the needs of modern enterprises, Java is the top choice for corporate application development.Java applications are the cornerstone of most enterprise websites nowadays due to their robustness, security, and scalability. High degrees of security are needed for these websites, which Java offers.

Large applications run more quickly thanks to its powerful memory management features, which also immediately remove any memory that isn’t being used. Trading sites, in particular, use Java since they need a strong performance to grow their audience.


To prevent security vulnerabilities, the JVM (Java Virtual Machine) that Java runs within verifies that the bytecode originated from an external system. Java applications are also simple to scale if the enterprise website experiences a spike in traffic. Most banking applications are made on the Java platform because it is the language with the highest level of security.

Java offers a multithreaded environment that enables numerous threads to run concurrently, enhancing system performance. One of the factors favouring Java over other programming languages is this.

5. Web Applications

Java is frequently used to create online applications, and it offers several web development tools, including JSP, Servlet, Struts, Spring, and Hibernate. These technologies make it easy for developers to design any web application based on the client’s requirements. Server-side components such as Servlets and JSPs contribute to developing the business logic of web applications.

JSPs, which are servlet extensions with more features than servlets and tags resembling those in HTML, are simpler to use than servlets because of this. These are the primary Java features that aid in creating web applications, and programmers can create any web application using these tools.

6. Application Servers and Web Servers

Today, the Java ecosystem comprises multiple web and application servers. Simple, Jo!, Rimfaxe Web Server (RWS), Apache Tomcat, and Project Jigsaw are all well-liked web servers. WebLogic, WebSphere, and JBoss EAP, on the other hand, dominate the business application server market.


7. Web Services

With its independence from platform and language, Java is a popular platform for creating web services. Java web services are easily consumable by programmes written in other languages. Both SOAP and REST-based web services are supported by Java, each with its benefits and drawbacks. REST is less secure than SOAP.

However, SOAP only supports the XML data format and has several development-related protocols that must be followed. On the other hand, REST is more frequently used than SOAP because it supports various data types, including JSON, HTML, and XML. Also, REST consumes less bandwidth when creating web services.


8. Artificial Intelligence

Java is one of the best languages for AI projects. It has appropriately integrated intelligent software into its infrastructure to increase AI programming. It has many great qualities, such as enhanced user interaction, ease of debugging, easily codable features, common widget tools, and many more. The use of Java improves the Artificial Intelligence process.

9. Big Data Technology

It is software designed to extract information from complex data formats.Deep learning, machine learning, and artificial learning all utilize them extensively. Java is a take on large data. Applications for extracting detailed information, such as Apatar, Apache Camel, and Apache Kafka, frequently employ Java.

Java has distinctive features, including an autonomous rubbish selection and stack provision mechanism when used further.Many factors make Java widely used in big data technology, giving it an advantage over other technologies.


10. Gaming Applications

Because of the availability of a large range of open-source frameworks, Java has proven to be the most desirable alternative for game creation.Popular games like Mission Impossible III, Minecraft, and Asphalt 6 are made on Java. It is an expert in developing 2D and 3D Android games because it supports the jMonkeyEngine and Dalvik Virtual Machine.


11.  Embedded Systems

It refers to aggregating small components that accomplish a bigger system’s joint function.Java has emerged as the most practical approach to managing the increasing complexity of software. Currently, a substantial number of embedded system developers use Java. Java’s extensive library options simplify the life of developers.

They can be easily reused by embedded applications, which significantly increases productivity. In addition, the inclusion of Object-Oriented Programming makes it easier for developers with little experience to create embedded systems. These Java characteristics make it simpler for programmers to manage complicated systems.


12. Cloud Applications

Cloud Computing refers to providing on-demand access to computer resources without the user’s direct management. Java has penetrated cloud application development. It provides an affordable alternative for IT infrastructure. In addition, it provides a platform for developing cloud servers and apps.
