This article is mainly used to put the focus on Java full stack development perspective and here I assume that you are already having the essential stuff which is also considered as a foundation for coding like Data Structures and Algorithms, and Networking, Protocols, Object-oriented programming, etc.

Here I am going to provide the tips which are useful for both Core Java developer for developing the front-end and Back-end development like server-side applications. The front-end and Back-end development in Java involves the logics such as JSP, Servlet, and JEE. Here I am going to discuss the few tips which are surely makes you to prepare yourself as Java Web developer whose primary job is to write web applications using Java technology. It shall also help you to become a full-stack Java developer in near future.

Software Design and Architecture:
  1. For any software developer the Software design and architecture are considered as the most important phases of the software development process.
  2. It is used to play a crucial role for designing any application Being able to see the big picture and think through the problem at hand.
  3. The chosen of right architecture and technology stack to implement your application more popular and demandable.
  4. If you are looking to accelerate your career in Java full stack developer, then I suggest you learn Software Design and Architecture.
  5. It mainly let you know about the Web Application & Software Architecture design which helps you to learn different architectural patterns like Microservice, client-server, and distributed application developments.
  6. It is the best course for not only senior developers but also every software developer out there as it will expand your thinking process and will you make more confident web developer.
  1. As we have already discussed that the Architecture is get changing constantly in the modern scenario so many companies are moving from monolithic applications to microservices architecture development.
  2. For the current requirement of the companies, it’s high time for Java full stack developers to learn Microservice architecture so that can build up their Career in this field.
  3. Here they will know how to create Microservices in Java to take advantage of this recent wave.
  4. Along with the Microservices another Spring framework provides Spring Cloud and Spring Boot which greatly simplify microservice development in Java. So, it is also very much effective and trendy for now a day.
DevOps Tools (Jenkins, Docker, and Kubernetes)
  1. For a modern Java full stack developer, knowledge of DevOps is essential. 
  2. As it is also very much effective and demandable at present scenario.
  3. If you are at least familiar with continuous integration and continuous deployment and how Jenkins helps to achieve that then it will add a great advantage to you.
  4. It becomes even more important for senior Java developers who often is responsible for setting coding best practices and creating environments, build scripts, and guidelines.
  5. For the present scenario, I also suggest you spend time and learn more about DevOps in general and explore the tools like Docker, Ansible, Kubernetes, AWS, etc along with Maven and Jenkins.
  6. If you need some resources then Learn DevOps: CI/CD with Jenkins using Pipelines and Docker in Udemy is probably the best course to start with. You will not only learn about CI and CD but also about Maven and Jenkins in depth.
Spring Framework (Spring Boot)
  1. It's almost imperative nowadays for a Java developer to learn Spring framework as most of the companies prefer to do development using Spring frameworks like Spring MVC, Spring Boot, and Spring Cloud for developing a web application, REST APIs Microservices.
  2. It also promotes best practices like dependency injection and makes your application more testable which is a key requirement for modern-day software.
  3. Being the Java full stack developer, you start with this Java and Spring tutorial to learn the basics of this awesome framework.
  4. Here in this case you are able to learn and get familiar with Spring then you should explore Spring Boot and Spring Cloud for developing next-generation Java application. It is being considered as the next gen Java application.
JUnit and Mockito
  1. If there is one common thing that separates a good Java developer from an average Java developer then its the unit testing skill.
  2. A good and professional Java developer almost always writes unit tests for his code and if he is really a Rockstar developer you can see that from his code and tests.
  3. Testing has also come a long way now with several tools for unit testing, integration testing, and automation testing available to Java developers.
Learn APIs and Libraries
  1. At the present requirement of the companies, the companies are also looking for the candidates who are having a good knowledge of the Java Ecosystem and APIs.
  2. If you have worked with great Java developers, you might have noticed their overall forms a major part of it.
  3. Java is the world's most popular and mature programming language and there are tons of libraries and APIs available for doing almost everything possible.
  4. The most important APIs like JSON processing APIs like Jackson and Gson, XML processing APIs like JAXB and Xerces, Unit testing libraries like Mockito and JUnit, etc.
  5. They are also very much trendy in now a day.
JVM Internals
  1. The Java has acquire its best unique feature due to because its portability nature.
  2. The java is become portable as it has a JVM concept which accept the .class file as input and run the program.
  3. Here the JVM internals like a hardware so the complete knowledge of JVM for Java developer is a must. Apart of this you must able to learn the different parts of JVM, how they work, JIT, JVM options, Garbage collections, and collectors, etc.
  4. If you know JVM (Java Virtual Machine) in well manner then you can write both robust and high-performance Java application.
  5. As part of this, you should also learn how to profile your Java application, how to find performance bottlenecks e.g. which objects are taking most of your memories and eating CPUs.
  6. For structured learning, I recommend Understanding the Java Virtual Machine series on Pluralsight. It's a very detailed and hands-on course, perfect for curious Java developers.
Design Patterns
  1. If you are writing a Java application from scratch then most of the time you are writing object-oriented code and design patterns are tried and tested solutions of common problems.
  2. By knowing and incorporating them into your code you make your application more flexible and easier to change in the future.
  3. It also improves overall code quality and documentation because other Java developers are also familiar with design patterns and they will understand your solution rather quickly.
  4. In addition with this, need to  focus on the code part, understand the spirit, and be creative. 
  5. If possible then spare some time with Java 8 features like lambdas and Streams to rewrite patterns like  Strategy patterns.
  6. At the bare minimum, If you are looking for some resources to learn design patterns then this list of design pattern courses is a good place to start with.
  1. It is also an extension application of Java which is enriched with the latest feature.
  2. A couple of years of the back I read a book called The Well-Grounded Java Developer which highlighted the advantage of becoming a Polyglot programmer.
  3. It inspired me to learn Scala and later I also tried Groovy because of its increased usage in creating build scripts and unit testing.
  4. It's a great language from JetBrains, the company behind IntelliJ IDEA, and also the official language for Android development as announced by Google in 2017.
IDE (Eclipse or IntelliJIDEA)
  1. One of the most important traits of better Java developers is that they are very good on their tools. They not only know more tools than average developers but also, they know their tools well.
  2. Since IDEs like Eclipse, NetBeans, and IntelliJ IDEA are the most important tool for a Java programmer, it makes sense to spend some time to learn better.
  3. You can learn about some plugins which make your task easy or some keyboard shortcuts which helps you to navigate better.
  4. Even some small tips help a long way because you use them a lot more than you think. If you are serious about taking your IDE skills to next level and use Eclipse, then I suggest you check Eclipse Debugging Techniques And Tricks on Udemy, a perfect course to improve your knowledge of Eclipse.
React or Angular
  1. In order to become a full-stack Java developer, you also need to know a front-end framework and there is no better choice than React or Angular. 
  2. These two JavaScript frameworks has completely changed how you develop web applications. As a Java developer, you might have used Servlet, JSP, and jQuery at the client side but its better to learn Angular or React because modern frontend development is using these frameworks. 
  3. AngularJS is a structural framework for developing dynamic web apps. It is a popular JavaScript framework written in JavaScript.
  4. The AngularJS is distributed as a JavaScript file, and it can be added to a web page with a script tag.
  5. It is basically used to extends the feature of HTML with ng-directives.
  6. The ng-app directive defines an AngularJS application.
  7. The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.
  8. The ng-bind directive binds application data to the HTML view.
  9. Depending upon whether you choose Angular or React.js, I suggest the following two courses to join to become a full-stack Java developer. 
    • Go Java Full Stack with Spring Boot and React
    • Go Java Full Stack with Spring Boot and Angular
    • Both are great courses to learn Angular and React with Spring Boot and become a full-stack Java developer. 
Learn Java Better
  1. Learning of Java is the best option for the developer, as it has a great future in ahead.
  2. Java is constantly updated and now with every new version in 6 months, it's a big challenge to keep yourself up-to-date. I have been learning  Java 10 features and  I know many programmers who have not written a single line of code using Java 8 features like lambdas and Stream API.
  3. Unfortunately, most of them are experienced Java developer with good 7 to 10 years of experience in their belt. I understand that at some point in your career learning becomes slow but if you don't act now you will be left behind.
  4. Almost all Java development jobs now required Java 8+ skills and if you don't have them, it would be very difficult to do well and perform well in your Java interviews.
