Popular Use Cases for Java in Different Industries

Java is an object-oriented, platform-independent programming language initially designed to build powerful web applications. Since its inception in 1995 by Sun Microsystems, it has evolved as a framework over the years, and almost 3 billion devices worldwide use it for development.

Java is used in different areas, such as embedded systems and enterprise solutions, making it an industry-leading technology framework. In the software world, it is fast emerging as the preferred choice across various industries. We can find Java applications being built for IoT, Artificial Intelligence, Big Data analytics, mobile development, etc.

Let's discuss its famous use cases in different industries and why you should use Java below.

Why Java?

The biggest reason developers select Java over other programming frameworks is its simplicity and ease of use. Java is very versatile, and its syntax is not complex for beginners to pick up.

Its most notable features are high portability, multi-threaded architecture, distributed application development, and robustness. Java supports loading classes dynamically and on-demand, supporting functions from other native languages like C and C++. It offers automatic memory management, dynamic compilation, and high performance.

Compared to other frameworks, it is faster, scalable, and more efficient than traditional languages. It can be used to design distributed applications and offers built-in security features via JAAS, cryptography, SSL encryption protocols, etc. No explicit pointers exist, and Java programs can be run inside virtual machine sandboxes. A classloader is a core component of the Java Runtime Environment (JRE), and Java can check for code fragmentation using its Bytecode verifier. Its security manager controls allocating resources to classes and access rights regarding reading and writing to the local disk.

What is Java Used For?

Java is used for building websites and scalable cloud apps and powers enterprise-grade applications. It is used for building and running various mobile apps and supports Artificial Intelligence and Internet of Things (IoT) applications. The framework can be used for building and deploying chatbots and integrating various marketing tools.

It is used to code everything from server-side technologies to big data applications. Java is swift, secure, and future-proof. It can also be used for designing games, and developers use it in data centers, supercomputers, mobile phones, and other devices.

Java I is considered the de facto industry standard for software development, and its Integrated Development Environment (IDE) is one of its most promising features. Automation tools, debuggers, and editors make it ideal for every development project.

New developers can learn Java gradually in two phases: core Java and advanced Java. The open-source programming framework includes extensive documentation and features excellent community support. It is known for having the second-largest Stack Overflow community, and its Application Programming Interface (API) can be directly used with any code.

What to Build with Java?

You can use Java to build various programs in different industries. As a fast-emerging framework, it helps software developers build applications for financial services, airline companies, electricity billing systems, etc.

Java can be used to build programs for innovative city projects and online medical and banking management systems. It is ideal for data visualization and can even be used in virtual private networks. There is no limit to what you can do, and many companies use the Java Enterprise Edition (Java EE) platform to facilitate easy scripting and designing enterprise applications.

Businesses can enhance their operations and security by leveraging its suite of various features. Java has established itself as a powerful player in the AI landscape. It can be used in natural language processing applications, neural networks, and deep learning projects. The possibilities are endless, and its robust architecture makes it an excellent choice for creating high-performance applications.

Although it is primarily designed for backend development, technologies like JavaFX and Swing make it ideal for front-end development and allow developers to build stunning graphical user interfaces (GUIs).

Java Development Use Cases

Here is a list of the most popular use cases of Java development:

  • It is one of the most used programming languages worldwide, and over 35.35% of developers use it to create apps, websites, and customized solutions
  • Java has a dynamic community backing support on GitHub, and it is becoming a popular choice for implementation with the latest advanced technologies, such as Augmented Reality (AR) and Virtual Reality (VR)
  • Companies hire Java programmers to build websites, custom software, and dynamic mobile applications. Spring and Hibernate are two popular Java frameworks leading organizations use to build web app components integrated with popular platforms like Twitter, Opera Mini, and Spotify.
  • The Java Netbeans IDE is ideal for creating captivating GUIs. Trapeze Artist Reader and ThinkFree feature 3D graphical models and advanced tree models to design advanced GUI applications. Java Micro Edition (J2ME) is excellent for cross-platform mobile application development. It has dynamic classes that can explicitly use the Dalvik Virtual Machine to design components for Android applications.
  • Java development is gaining popularity in the finance industry, too. Several institutions use Java to build exchange platforms, digital wallets, and banking data handling frameworks.
  • Developers use Java in SIM cards to power telephone apps in the real world. It's an innovation recently gaining prominence, and Java development services are being incorporated with embedded systems.
