The 2023 Java Developer RoadMap UPDATED Leave a comment

In Advanced Java, you don’t need to learn everything in detail but you just be aware of all the above things and how those are working. And whenever you are working on these particular things you can read about them and you can implement them in your project. If you want to learn Java FX in 2023 and need a resource then you can also check out the Java FX Concepts Bootcamp 2023 course on Udemy. First, your IDE, which is your primary tool and can do almost everything you asked for like compile, run, debug, profile, test, compare files and code, refactoring, and much more. If you want to learn more about Computer Science, you can also check out Introduction to Computer Science and Programming Specialization by University of London. The HTTP protocol is the backbone of the web, and a good knowledge of both HTTP and HTTPS is mandatory for a web developer.

If you are interested in that, Frank Delporte has a great course Use Java and Java FX on a Raspberry PI for beginners. If you want to develop a GUI application like NetBeans, one of the famous Java editors which are also written in Java then you can learn Java FX in 2023. I wouldn’t advise learning Swing unless you are working for a bank that is paying you thousands of dollars per month maintaining their Swing-based trading GUI. Java offers great APIs like Swing and Java FX for developing GUI clients. Swing was really popular a couple of years back but C# has now taken lead but Java FX is another popular Java API for developing GUI applications in Java. If you need more options than you I have already shared a lot of resources like books and courses, you can check those to learn more.

The Start of Your Backend Journey — Node.js and NPM

There is no doubt that every programmer should know Git and Github as they are the standard in terms of version control and code repository. If you want to learn and master Design Patterns, particularly OOP Design patterns then I suggest you join the Design Patterns in Java course by Dmitri Nestruk on Udemy. This is a great course to learn the modern implementation of classic design patterns in Java. As a programmer, you should be familiar with Git and Github, essential Git concepts like a branch, master, checkout, checking, push and pull, as well essential git commands like git diff, git commit, etc.

Here is a list of Java developer salaries across different countries and a high rate of web development job opportunities. Meanwhile, the average salary range is based on skills and experience self-reported from Talent. ElasticSearch is getting popular as more and more applications are now providing a way to analyze and visualize their data to the user.

No SQL Databases

This includes the code that interacts with the database, handles user requests, and provides the functionality that users see and interact with. Before diving into backend development, you should have a strong foundation in basic computer science concepts, like algorithms, data structures, and object-oriented programming. It is also important to have knowledge of databases and database design, as well as programming languages like Python or Node.js, and web frameworks like Django or Express.js. A backend developer is a software developer who specializes in building and maintaining the server-side components of a web application. This includes the server, database, and application logic, as well as the APIs and other interfaces that connect the backend with the front end of the application. Backend developers work with programming languages such as Java, Python, Ruby, and PHP, as well as databases such as MySQL, MongoDB, and PostgreSQL.

  • Use these APIs to further build your knowledge of Java programming.
  • Multithreading means a process of executing two or more threads at one time for the utmost utilization of the CPU.
  • The goal of Eclipse of MicroProfile is to define standard APIs for building microservices and deliver portable applications across multiple MicroProfile runtimes.
  • Just take an example, let’s say you are ordering some item from Alibaba via the mobile application, so here you’re establishing a connection with Alibaba’s API.
  • This includes topics such as algorithms, data structures, programming languages, and computer architecture.
  • However, Java streams are self-explanatory when you understand the concepts behind them.

Server-side caching involves storing data on the server-side to reduce the time needed to generate a response. APIs provide a standardized way for different applications to exchange data and functionality, making it easier to integrate different software platforms. They also work closely with front-end developers to ensure the seamless integration of the application’s user interface and functionality.

How to Create a Discussion Forum Using PHP and MySQL?

It works by sending a POST request to a URL provided by the receiving application, which can then process the data or trigger a specific action based on the information received. Webhooks are commonly used in integrations between different web services, such as sending notifications to a messaging app when a new email is received. Code analysis tools are software tools that analyze source code to detect potential errors, bugs, and security vulnerabilities. They provide automated and systematic approaches to detect issues in code that may not be apparent to the developer during manual testing. These tools use various techniques such as static analysis, dynamic analysis, and code coverage analysis to provide insights into code quality and identify issues. Overall, APIs are a crucial component of modern software development and enable developers to build more powerful and innovative applications by leveraging the capabilities of other software platforms.

Also, it is important that you learn Data Structure and Algorithms before becoming a back-end developer because it will help to make the code more optimized and efficient. Once you’ve decided on the language which you need to work on, you need to brush up skills with the framework as well. The framework is a backbone of a language on a program/application on which you’re working. There are certain frameworks that you might consider working on while working as a back-end developer. Docker is an open-source containerization platform, that enables developers to package applications into containers.

WebAssembly is a new type of code that can be run in modern web browsers and provides new features and major gains in performance, to power backends. Backend frameworks are usually based on front-end counterparts, such as React and Vue, strictly connecting your backend to your front-end. There’s no better way to retain notions than doing and solving problems.Sometimes, finding backend projects to practice sounds hard though.

This way you will gain experience easier with the help of your senior colleagues. As a beginner, you’ll need to make sure you understand the fundamentals before moving on to more advanced topics. For example, it’s essential to know how to code before you learn how to make a REST API call. Developing a good network is crucial for finding job opportunities and advancing your career. Networking involves building professional relationships with people in your industry, such as colleagues, mentors, recruiters, and alumni. Networking can be done both in-person and online through social media platforms such as LinkedIn.

Java Backend Roadmap

It is very obvious that a backend developer should have knowledge of programming languages to implement their coding skills. Java is one of the most recommended languages to learn for backend developers, but it’s not important to stick to Java for programming. You can also opt for languages like Javascript, C#, Python, Ruby, and PHP.

So, if you want to sell your website, building only the front-end won’t work if you do not have support to hold it and that support is – Back-End. Web Servers
The Apache, or you can say Apache HTTP Server, is an open-source cross-platform web server that was developed by the Apache Software Foundation. NGINX is another open-source web server that is also being used for reverse proxying, load balancing, caching, mail proxying, and more. A strong network can provide access to job openings, insider information about companies, and referrals to hiring managers.
