Along with that, here are 11 tips that will instantly make you a better Java developer.

11 Tips to become a better Java developer

Java developers rely on programs and tools for development. While there is a plethora of programs and tools, we have chosen the best and the easiest tools and programs that help you become a better Java developer

Jenkins

Continuous integration is an integral part of any Java software. Software development involves continuous building, testing, deployment, and automation. Jenkins is an excellent open-source server that provides automation functionalities via hundreds of plugins. Jenkins is a popular choice because it is easy to install and configure. Jenkins is your key to becoming a better Java developer.

Docker and Kubernetes

DevOps is an essential requirement in these fast-paced times. It ensures the timely delivery of applications and services. It also improves scaling, collaboration and security. Docker and Kubernetes is your gateway to implementing DevOps tasks. Docker helps you set up automatic deployment across servers, machines, data centers, and the cloud. Kubernetes makes the code deployment process easy via rapid rollouts of new releases.

Git

Git is a very popular open-source version control system for developers. Git makes sustaining projects easier. Git is free, fast, and lightweight. Learning Git is an important step to becoming a better Java developer.

Learning Design Patterns

Design patterns are paramount to Java development. They have many advantages. Other developers find it easy to modify Java applications that follow design patterns. They also provide more flexibility and efficiency to applications. Most of the best Java books cover design patterns.

RESTful Web Services

REST API and RESTful Web Services are in great demand in the software and web development world. Based on REST Architecture, RESTful Web Services are widely used for web-based application APIs. They are popular because of their lightweight nature, scalability, and easy maintenance.

Unit Testing (JUnit and Mockito)

Java developers must have a thorough knowledge of unit testing. Most of the best Java books shed light on unit testing. Unit testing ensures that different components of your code work correctly. Several tools make unit testing easier. JUnit and Mockito are the two most popular unit testing tools. JUnit helps you identify bugs early on to ensure error-free code. On the other hand, Mockito lets you test different functionalities in isolation using dummy implementations of interfaces and classes.

APIs and Libraries

Java is a treasure chest of APIs and libraries. Developers heavily rely on these APIs and libraries. It is difficult to learn about all of them. But, learning about JSON processing APIs, XML processing APIs, and the aforementioned unit testing libraries Mockito and JUnit is paramount. Knowing about parsing, concurrency, logging, database, and HTTP libraries helps you become a better Java developer. The best Java books and online courses have chapters dedicated to important APIs and libraries.

Spring Framework

Spring is an application development framework that is immensely popular among Java developers across the world. Its popularity stems from its efficiency, ease of use, and reusability. Spring is also known for its Aspect-Oriented Programming approach. Spring Framework has several other advantages that you will learn as you dive deep into it.
