Top 10 Skills to become a full-stack Java Developer

As we all know that the Java is the most emerging area where now a day most of the companies are migrating for developing their application. Now I am going to provide the tips which are useful for Java developer for developing the front-end and Back-end development like server-side applications. During the designing of front-end and Back-end part using Java basically involves the logics such as JSP, Servlet, and JEE and framework.

Here I am going to discuss the few important skills which are surely makes you to prepare yourself as Java Web developer whose primary job is to write web applications using Java technology. I believe it should definitely help you to become a full-stack Java developer in near future.

Microservices

As the Architecture of the applications are getting change continuously and frequently in the present scenario so many companies are moving from monolithic applications to microservices architecture development. 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. 

Along with this they can also have the following benefits in microservices environment such as,

1. Here they will know how to create Microservices in Java to take advantage of this recent wave.
2. 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)

For the present scenario the knowledge of DevOps is essential for Java full stack developer. As it is very much effective and demandable and well suited to present requirements. Here I would like to discuss the important tools like Jenkins, Docker, and Kubernetes which are more frequently going to use in the DevOps environment.  As per 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.

1. 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.
2. 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.
3. 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.

1. It also promotes best practices like dependency injection and makes your application more testable which is a key requirement for modern-day software.
2. Being the Java full stack developer, you start with this Java and Spring tutorial to learn the basics of this awesome framework.
3. 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

It is another important skill which is being in demands since long. 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. If there is one common thing that separates a good Java developer from an average Java developer, then it’s the unit testing skill.

Learn APIs and Libraries

If you have worked with great Java developers, you might have noticed their overall forms a major part of it. Presently many companies, are looking for the candidates who are having a good knowledge of the Java Ecosystem and APIs. 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. I should suggest you to go for the following tools at a prior for best effectiveness in using the API’s.  

1. 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.
2. They are also very much trendy in now a day.

JVM Internals

As we all know that the Java is become portable as it has a JVM concept which accept the .class file as input and run the program. Here to make this feature of java enable the JVM is responsible. 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.

1. If you know JVM (Java Virtual Machine) in well manner, then you can write both robust and high-performance Java application.
2. 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.

Prerequisites to Become a Full Stack Java Developer

Design Patterns

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. 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. But in addition with this, need to focus on the code part, understand the spirit, and be creative.
