In digital words, Java has always featured on the list of popular programming languages. Java stands out from other programming languages in terms of its security and functionalities. Java is often used for web applications with heavy workloads such as those used in the fin-tech and banking sectors. Several popular websites, e.g. Linkedin, Amazonaws, Indeed, etc. use Java for programming their servers.
Java has always been considered a surreal choice for web applications, even though it can process thousands of transactions simultaneously without any hassles. If you’re looking to build a dynamic and interactive web application using Java, you’re in the right place. In this comprehensive guide, we’ll walk you through the process of creating a dynamic Java web application from start to finish. Let us have a look at the reasons why companies hire Java developers for web app development.
How to Create a Dynamic Java Web Application
Java is Scalable
Scalability is a crucial factor to be considered while selecting a language for web apps, especially for growing businesses. A web app developed in Java can easily be scaled due to the wide availability of its components. The Java web app supports both horizontal as well as vertical scaling. Java is flexible enough to implement any business logic. So, once the business decides to enhance the performance or response time of its website, it is only a matter of hours.
Choosing the Right Web Framework
Selecting the appropriate web framework is crucial to ensure efficiency and maintainability in your project. Java offers several powerful frameworks like Spring MVC and JavaServer Faces (JSF), which provide the structure and tools needed for developing dynamic web applications. These frameworks facilitate tasks such as handling requests, managing sessions, and rendering dynamic content.
Importance of Code Refactoring in Software Development?
Java is Portable
A common issue faced by developers is the diverse hardware and software platforms on user machines. Java is the preferred language for cross-platform development. The Java compiler compiles the code into an intermediary language called bytecode. The bytecode is then executed by an interpreter called Java Virtual Machine, written for that specific hardware platform.
Java applets are delivered as bytecode, to the browser for executing web apps. Applets are used to provide functionalities varying from games to animations to web apps. So, once a Java web application is ready, it can be used on any platform irrespective of the device or operating system. It is due to the portability of Java only that a business can even hire Java developers online.
Java Manages Memory Automatically
A common problem faced by businesses is the lack of proper memory management modules in their web app. A Java web app allocates and de-allocates memory to objects as and when required automatically. Java uses the “Garbage Collection” system to do this task. Objects no longer required are deleted automatically without any explicit code. Hence, the performance of the web app does not suffer due to memory-related issues. Apart from this, it saves precious development time, for which businesses are billed heavily.
The backend of your application involves writing Java classes that handle data processing, business logic, and interactions with the database. Also create classes to manage user authentication, data manipulation, and other core functionalities. Use the principles of Object-Oriented Programming (OOP) to create well-organized and maintainable code.
Java Supports Multi-Threading
A common requirement in web apps is the module for managing multiple users simultaneously. Java web apps can manage multiple users by creating an independent thread for everyone inside the program. It avoids the need to run multiple copies of the same program leaving the server drained. Each thread lives until the job finishes. This facilitates quicker response time, support for simultaneous operations, and fewer glitches. It also saves on maintenance costs and enhances the performance of the app due to the optimal utilization of cache and server resources.

Conclusion
Due to the emergence of modern web development tools like PHP, companies are reluctant to use Java for web app development. Java is gradually catching up with these technologies by launching new features regularly. Java including the latest version 17 LTS on the Java SE Platform in September 2023. The features mentioned above are an indication of how Java can be used to develop a robust, agile, and pocket-friendly web app. To conclude, Java (one of the old warhorses) is preferably a better choice for web apps if one wants to maintain longevity.
FAQs
Can Java develop dynamic web-based applications?
Yes, Java is well-suited for developing dynamic web-based applications. Java’s robustness, portability, and versatility make it an excellent choice for building interactive and feature-rich web applications.
How to convert Java project into a dynamic web project?
Converting a Java project into a dynamic web project involves a series of steps to enable web functionality and interactivity. Here is Project Setup, Add Web Capabilities, Web Content, Servlets and JSPs, Deployment Descriptor, Server Configuration, Testing and Debugging and Refinement.
How to create a website using Java code?
To create a website using Java, set up a development environment with tools like Eclipse or IntelliJ. Use JavaServer Pages (JSP) for dynamic content, and servlets for server-side logic. Combine HTML and CSS for the front-end, and Java for back-end processes. Integrate a web server like Apache Tomcat. Develop features with Java libraries and frameworks like Spring. Test the site locally, then deploy it on a hosting platform. Regularly maintain, update, and secure the site for optimal performance.
How to connect Java code to HTML?
To connect Java code to HTML, use JavaServer Pages (JSP) or servlets. In JSP, embed Java code within HTML using <% … %> tags. Create servlets to process requests, generate dynamic data, and interact with Java logic. Use form submissions or AJAX to send data from HTML to Java, and JSP or servlets to display Java-generated content in HTML. Ensure the web server, like Apache Tomcat, is configured correctly. This integration allows seamless interaction between Java’s backend functionality and HTML’s frontend presentation.
