Java Web Development Introduction
Java is an open-source, popular programming language used predominantly for web development in the form of desktop applications, and mobile applications. Java in web development (website development or web application development) creates server-side websites and web apps that can effectively manage massive user data and handle high traffic efficiently.
Do you know? According to the TIOBE Index for 2024, Java holds the 4th position among the top programming languages globally. It remains a highly preferred choice for enterprise-scale applications due to its stability and security features. Java’s automatic memory management can process large amounts of data for backend development.
Since, Java is a “Write Once, Run Anywhere” (WORA) language, Java can operate on any computer, regardless of its operating system. It is relatively simple, easy to understand, work and develop. It is popular among top companies due to
- Easy to learn and use
- Object-oriented Programming Language
- Secure
- Platform Independent
- Distributed language
Thus, Java development company have grown especially in demand, because of Java is one of the most important languages known for its portability; it is used in the development of websites because of its set advantages. Let us discover these functions and the types of Java that make it preferred among software developers.
Functions of Java Web Development
Amazon, the world’s largest retailer relies on Java for its expanding e-commerce platform. Java is being trusted by more leading companies like Google, Metaplatforms, Microsoft, Uber, Airbnb, Netflix, Spotify, Intel and Paypal. When Java is used to develop a mobile application, it can fit into mobile, desktop, and software interfaces. Java continues to be their best choice for web development.
1. Java in Application Development
- Mobile Applications: Android uses Java for many of its applications mainly because of its open libraries. By using application development tools powered by Android Studio and successfully integrating libraries like Retrofit and OKHTTP, developers can design feature-rich and high-performance mobile apps.
- Desktop Applications: Java has stunning GUI creation frameworks such as Java’s Swing and JavaFX for designing powerful graphical user interfaces for desktop applications. These tools provide rich functionality for developing GUIs, which are used in providing end-users with optimal experience.
- Software Applications: In addition to mobility and the PC, Java is used for enterprise applications that are of business-critical value. These applications utilize Java concurrency utilities, networking, and highly secure web services that result in high performance and reliability.
2. Website Development
Java plays an important role in both static and dynamic website development and its main strength lies in its ability to work with different technologies and frameworks depending on the needs of the webpage.
Static Websites: It does not involve Java itself in creating static HTML-based pages but may employ Java during the creation process of static content. For example, in static websites, people can use HTML pages containing images, CSS to style, and small scripts of JavaScript for interactivity.
Dynamic Websites: Java also excels when it comes to dynamic websites, with its technologies such as servlets and Java Server Pages, otherwise abbreviated as JSP. They enable developers to generate content that is dynamic based on user activities and server performance.
Servlets: Java Servlets interact with clients who request some dynamic content and Servlet processes this request and returns the answer to the said client. Since web applications that have server-side processing capability are developed, they are vital.
JavaServer Pages (JSP): Java codes when integrated with HTML can create JSP websites. It facilitates the development of web ‘pages’ to display the results of server-side processing.
Why Choose Java Programming?
- One of today’s most fruitful programming and development endeavors is web development. Since its inception in the programming community, Java has played a significant part in making it one of the most widely used languages today.
- The Java programming language and its frameworks give you flexibility and power for developing Java web application with benefits of all sizes, from simple web pages to robust e-commerce website. Java may be used for more than just instant messaging, message boards, blogs, and email.
- Java development technology is widely used in web banking and fintech applications. In some form, Java is installed on nearly 3 billion devices. Millions of requests are processed every day by Java Server programs, which are used by many J2EE web application development companies.
Types of Java Web Development
Java web development can be broadly classified into three distinct types, each focusing on different aspects of web development:
1. Front-end Web Development Using JavaFX, Vaadin or GWT
To make websites user-friendly, Java supports front-end development through these popular frameworks, a must-have framework:
JavaFX: JavaFX is a toolkit that helps create a User Interface for Building Rich Internet Applications (RIA). Using this toolkit, developers can create user-friendly interfaces and run on all devices without complaints.
Vaadin: Vaadin is a popular Java framework for web applications. It is an efficient choice due to its high running speed with a large set of pre-built UI elements. This framework gives apps a unique and attractive design, which is mainly used for e-commerce.
GWT (Google Web Toolkit): Indeed, with GWT, developers can write pure client-side code primarily in Java, which is further compiled into highly efficient and rich JavaScript. This approach makes use of the solidity of Java in enhancing front-end development.
2. Backend Development using Java Server
A lot of user data on platforms like Facebook and Instagram needs to be maintained by robust backend systems supported by Java.
To reiterate, Java is strong where it works – backend development is a notable area, where Java is popular for its stability and reliability.
Spring Framework: Spring is the best Java framework toolkit for creating enterprise-level backend applications. It supports dependency injection and aspect-oriented computing and handles business transactions perfectly.
Spring Boot: Spring Boot is a module that builds on the Spring framework, filling in the gaps that need to be removed to bring a specific Spring application to the production level immediately. They include TOMCAT and JETTY among other facilities for developing and deploying web services.
Java EE (Enterprise Edition): Enterprise features are implemented through a set of specifications designed for the platform and include support for distributed computing and web services. These constituents are known as Servlets, Java Server Pages or JSP, and Enterprise Java Beans or EJBs.
Apache Struts: Struts is a Java framework to develop web applications for model 2 style architecture MVC stands for Model View and Controller. A prime advantage of MVC architecture is that it can easily help in the disintegration of business logic from presentation, which in turn makes the application more maintainable and scalable.
3. Database Management Using Java Database Connectivity (JDBC)
Database management is an essential domain required by all companies, and Java provides the appropriate solutions for database management.
Hibernate: Hibernate is an ORM (Object-Relational Mapping) that brings ease to managing a Database by mapping a Java file or object to a table in the database. It hides the database details, which simplifies the processes that work directly on databases and leaves business logic to the developers.
JPA (Java Persistence API): JPA is a specification for ORM in Java. It consists of a set of interfaces for dealing with relational data in Java, generally offered in tandem with Hibernate.
