Java is a popular programming language that has many real-world applications. This blog post enumerates some real life Java applications. We will also provide links to code examples for each application. So, whether you are a Java beginner or an experienced programmer, you will find something interesting in this blog post!

Desktop GUI Applications

One of the top utilization of Java language is for graphical user interface (GUI) apps. GUI applications are typically created using the Java Swing toolkit. When developing a GUI application in Java, you need to use a windowing toolkit. A windowing toolkit is a set of tools that allows you to create graphical user interfaces (GUI) components, such as buttons, text fields, and scrollbars. You need to use a windowing toolkit because GUI components are not part of the Java language. There are many toolkits available, such as the Java AWT toolkit.

Web Applications

A web application is a software that a user accesses via a web browser (ex., Internet Explorer, Google Chrome, Mozilla Firefox) to perform tasks or retrieve information from a server. The server is usually a web server, such as Apache Tomcat, Microsoft IIS, or Oracle WebLogic Server. A web application comprises HTML, JavaScript, Java and CSS files. The HTML files are the pages that are displayed in the web browser. The Servlets and JSPs are the media by which Java offers support for web apps.

Mobile Applications

A mobile application, also known as an app, is a program that runs on either a smartphone or tablet. Mobile applications are typically created using the Java ME platform. Java ME is a mobile-device-specific subset of the Java SE platform. Mobile apps can be found in app stores like the Apple App Store and Google Play store.

Embedded Applications

An embedded system is a device with a specific purpose, and an embedded application is software written to perform a task on that hardware. Embedded systems are designed to serve a single purpose. Embedded systems are typically used in devices that are not normally considered to be computers, such as automobiles, televisions, and microwave ovens. 

Embedded applications are typically created using the Java ME platform. So that the device can interact with the user, embedded applications often have a graphical user interface (GUI).

Cloud Applications

A cloud application is a type of software that you can access and run from anywhere, as long as you have an internet connection. A cloud computing environment is a network of computers that are connected over the Internet. This type of system allows for greater flexibility and scalability than traditional on-premise systems. 

Cloud applications are typically created using the Java EE platform. Java EE is a superset of the Java SE platform that adds enterprise features, such as support for web services and databases. Applications can either be deployed in a public cloud, like Amazon Web Services (AWS), or a private cloud hosted by the organization.

Internet of Things (IoT) Applications

An IoT application is a software application that operates on an IoT device. IoT devices are any gadgets that can connect to the internet and collect or send information. IoT devices can include sensors, cameras, and home appliances. IoT applications are typically created using the Java ME platform. The Java ME platform is designed for mobile devices, and it uses a subset of the Java SE platform.

Java Card Applications

A Java Card application is a software application that runs on a Java Card. A Java Card is a type of smart card that can be used to store data, such as personal information, credit card numbers, and loyalty points. Java Card applications are typically created using the Java Card platform. The Java Card platform is a subset of the Java SE platform that is designed for smart cards. Java Card applications can be used to create loyalty programs, store personal information, and make payments.

Machine Learning Applications

A machine learning application is a software application that uses machine learning to make predictions. Machine learning is a kind of artificial intelligence that can be used to learn and enhance data automatically. Machine learning algorithms can catch ways in data and then utilise those patterns to produce forecasts or recommendations. Machine learning applications are typically created using the Java EE platform. Java EE is a superset of the Java SE platform that adds enterprise features, such as support for web services and databases. Machine learning applications can be used to predict customer behaviour, credit risk, and fraud.

As you can see, the Java platform can be utilised to build many various kinds of applications. With versatile variations and different java security testing methods, it’s never been easier to build something on java.

Conclusion

Now that you know about the different types of applications that can be created using the Java platform, you can choose the right platform for your application. We hope the above writing will be useful to you.
