What is the difference between the frontend and the backend Java developer?
The front end and back end are two essential parts of any application. What your users see is known as the front: visual things like buttons, checkboxes, graphics, and text messages.
It allows your users to communicate with your application. The backend is your application’s data and the infrastructure that makes it possible. That is where your application data is stored and processed for your users.
How does the front end of an application work?
The front end refers to the graphical user interface (GUI) with which your users can interact directly, such as navigation menus, design elements, buttons, images, and graphs.
Technically, a page or screen your user sees with several UI components is called a document object model (DOM).
Three main computer languages influence how your users interact with your frontend:
- HTML defines the frontend structure. Different types of DOM elements are represented.
- CSS defines a web application’s style, which can include layout, fonts, color, and visual style.
- JavaScript adds dynamic functionality by modifying the DOM.
- It can refresh a page and show other content. This means the front end could handle straightforward user actions or requests, such as making a calendar appear or determining whether a user has entered a legal email address. However, more complex requests will be forwarded to the backend.
How is an application’s backend written?
This can sometimes be referred to as the server side because the backend of your application manages the general functionality of your web application.
When your user interfaces with the front end, the interaction makes an HTTP request to the backend. The request is processed, and a response is returned.
Upon encountering a request, your backend generally interacts with the following:
- Database servers to retrieve or modify relevant data
- Microservices that do a part of the work requested by your user
- Third-party APIs to trigger extra requests or actions
- The backend uses diverse communication protocols and technologies to fulfill a request. It also serves thousands of different requests concurrently. Techniques of concurrency and parallelism, such as request distribution among many servers, caching, and data replication, are also combined in the backend.
Key Difference Between Frontend and Backend Java Developer
When learning about web development, many aspiring developers will ask what the difference is between front-end and back-end Java developers.
Such differentiation will be essential to everyone seeking to specialize in either the front or backend side. This role would comprise user interface design aesthetically and functionally.
Frontend developers typically employ technologies like HTML and CSS, which are then more closely linked to Java frameworks like JavaServer Faces (JSF) or Vaadin.
Regarding the discussion of frontend vs backend Java developers, frontend developers emphasize user experience and design more.
Conversely, a backend Java developer has to handle the server side of an application. In this particular job, he would be about writing the logic that powers an application, managing database queries, and everything would be perfect backstage.
The nature of these applications is very robust and depends on frameworks like Java, such as Spring and Hibernate. This brings us to another critical point regarding the frontend vs. backend Java developer; that is, while the frontend developers work on what users see, the backend developers work on the application’s functionality and performance.
In short, this difference between frontend and backend Java developers is critical for anyone entering the web development field.
Both roles call for different skill sets and work on different parts of the application lifecycle. Thus, awareness of these differences will help developers make career choices and areas of specialization.
Whether one specializes in frontend or backend development, both roles are integral to web applications.
