Top Skills to Become a Full-stack Java Developer

The top skills to become a full-stack Java developer include proficiency in Java and related frameworks, knowledge of front-end web technologies, understanding of databases and SQL, experience with DevOps tools, proficiency in debugging and problem-solving, and good communication and collaboration skills.

Programming languages: Java, JavaScript, HTML/CSS, SQL

As mentioned earlier, knowing the basics of web technologies is necessary.

HTML/CSS stand for Hypertext Markup Language and Cascading Style Sheet. HTML and CSS are markup languages that work together to create and style web pages. HTML provides the structure and content of the page. It is the first building block of the website. While CSS is used to define the presentation and layout of the content. It is used to style the content that is written. Together, they form the foundation of web design. When combined with JavaScript, they can be used to build dynamic and interactive web applications.

JavaScript is the most popular language for development. It is the most vital language needed for full-stack development. It adds interactivity and dynamicity to web pages. JavaScript is a scripting language that runs on the client side and is used to enhance the interactivity of web pages. It enables developers to modify web pages' Document Object Model (DOM) and add advanced features. JavaScript is commonly used in combination with HTML/CSS to create engaging and dynamic web applications.

Java is used on the server side to create web applications. It follows an object-oriented programming paradigm, making it reliable and scalable. Java is commonly utilized along with web application frameworks like Spring or Apache Struts to streamline the development process of web applications.

SQL is Structured Query Language. It is a database of the relational type that is used to store the generated data. A full-stack developer must be aware of various relational, and non-relational, how to write queries, and memory storage. It is commonly used in conjunction with Java to store and retrieve data from databases. Java full-stack developers should have a good understanding of SQL and how to use it to interact with databases.

Front-end frameworks: Angular, React, Vue.js

In a Java full-stack application, Angular, React, and Vue are used to build user interfaces.

Angular is an open-sourced JavaScript framework used to create mobile and web apps. It is based on TypeScript and created by Google. Angular offers two-way data binding, component-based routing, form validation,`` dependency injections, etc.

React, developed by Facebook in 2011, is a widely used JavaScript library for creating UIs, capable of supporting both heavy and simple applications. Maintained by Meta and a community of independent developers, React's key advantage is its utilization of Virtual DOM, a JavaScript version of the real DOM that allows for seamless data exchange without requiring a page reload.

Vue.js is a JavaScript-based open-source framework that allows developers to create user interfaces and single-page applications. It uses a component-based and reactive approach, providing a straightforward and user-friendly experience. With features like two-way data binding and a reactive system, Vue.js ensures high performance with simplicity and ease of use.

Overall, they provide enriched user interfaces to work with Java full-stack developer skills.

Back-end frameworks: Spring, Hibernate, Node.js

The back end is also one of the important aspects of being a Java full-stack developer. The backend is one of the most vital parts of full-stack development.

Spring is an open-source framework for building Java applications. It offers a variety of powerful tools and features for web development, such as dependency injection, AOP, MVC, and data access. Spring is a popular choice for Java full-stack developers because it offers a variety of tools for building scalable web apps, including Spring Boot, Spring MVC, Spring Data, and Spring Security.

Hibernate is a Java Object-Relational Mapping (ORM) framework that maps Java objects to database tables, providing features such as caching, lazy loading, and transaction management, which simplify database access and increase productivity.

Node.js is a cross-platform JavaScript runtime environment for building scalable, real-time web applications using an event-driven, non-blocking I/O model. Developers can run their code using Node.js before deploying it on the web. It has a large ecosystem of packages and is known for its ease of use, speed, and versatility.

Therefore, using these frameworks eases development and makes it easier to maintain and update the application over time.

Databases: MySQL, MongoDB, Oracle

When it comes to being a Java full-stack developer, MySQL, MongoDB, and Oracle is the popular choices. The choice of which database to use will depend on the project's specific needs. The full-stack Java developer will look into the same.

MySQL is a relational database. Supported by Oracle Company, it is an open-source database software that is known for its fast, scalable, and user-friendly features. It is used with JDBC to integrate with the database.

MongoDB is a NoSQL database that is often used for developing web applications that require the management of significant amounts of unstructured data. Integration with Java applications is possible using the MongoDB Java Driver, which offers a proper API for interacting with the database.

Web technologies: REST APIs, AJAX, JSON

As a Java full-stack developer, you must know web technologies like REST APIs, AJAX, JSON, etc.

REST stands for Representational State Transfer is a web service architectural style that uses HTTP protocol to transfer data between client and server. For Java full stack you can use Spring Boot or Jersey to create REST API.

AJAX is used to create asynchronous web applications. To implement AJAX for Java full stack, libraries like jQuery or AngularJS are the best choice.

JSON stands for JavaScript Object Notation. JSON is a format for exchanging data that is lightweight and easy for humans to read and write and for machines to parse and generate. Its common usage is for transferring data between a client application and a web server. Java developers can utilize libraries such as Jackson or Gson to parse and generate JSON data.

DevOps: Docker, Kubernetes, Jenkins

DevOps refer to practices that combine software development and IT operations to shorten the development lifecycle and ensure high-quality software delivery. Some of the most popular DevOps tools include Docker, Kubernetes, and Jenkins.

Docker is a platform that is used to create, package, and deploy applications as self-contained containers. These containers are lightweight, and flexible, and offer a consistent runtime environment across various operating systems. When working as a Java full-stack developer, Docker is often utilized to bundle applications along with their dependencies into a container, for deployment and management.

Kubernetes is an open-source platform that automates the deployment, scaling, and administration of applications in containers. It offers a reliable and adaptable infrastructure for executing Docker containers, which simplifies the deployment and management of containerized applications in production settings.

Jenkins is an open-source automation tool that allows developers to automate various stages of software development, such as building, testing, and deployment. It is used to automate software delivery, starting from source code management to production deployment. When working on Java full-stack development, Jenkins is often utilized to automate continuous integration and delivery of applications and to fasten the process of managing and deploying updates.

Other skills: Git, Agile methodology, Testing frameworks

Git is a version control system that developers use to manage code changes and work collaboratively with others. It enables concurrent work for a codebase, merging changes, and rolling back to prior versions.

An agile methodology is an approach to managing software development projects. It is a straightforward and efficient way to transform a business idea into software solutions. Agile refers to software development methods that involve ongoing planning, learning, teamwork, gradual development, and early delivery.

Some popular testing frameworks for Java full-stack include JUnit, TestNG, Selenium, etc. The choice depends on the needs of the projects. JUnit and TestNG are suitable for unit testing, while Selenium is ideal for web applications.
