There are numerous programming languages available for programmers and developers today, including C, C++, and Python. Among these, Java stands out for its versatility, as it can be used to create customized applications that are both fast and lightweight. Programming languages are crucial for shaping a developer’s career, enabling the creation of various apps, impressive websites, and numerous software products that surround us.
Industry giants like Amazon, Google, and other major players utilize Java extensively and maturely. Mastering Java positions individuals at the forefront of the industry, and many companies actively seek developers proficient in this language. Before diving into 'how to master Java' and related information, let's first discuss the popularity of Java.
Steps to follow for becoming a Java developer
Start with fundamentals of core Java
The first step to becoming a good Java developer is to learn all the fundamental topics of the language. this includes syntax, data types, oops concepts, collection framework, String, Exceptions, Threads, etc.
Every Java developer should have a clear understanding of at least Java 8 and its features.
Continue Practicing hands-on
Always try to learn by solving problems from the start such as calculating the sum of two numbers. As we progress we work on more complex problems and applications. This will help us understand real-time errors and how we will fix those errors.
Learn the Basics Of Database
As a developer, it is important to have a basic understanding of a database and how it works. Like SQL, JDBC, ORM Frameworks, and Database design.
Do Practice on Jakarta EE/Advanced Java
when we are done with core Java and a basic understanding of databases now we will move on to advanced Java. It gives us experience in real-time projects.
You will also get to know how to use a web server or application server in this part. Moreover, knowing Java EE also helps you to understand modern frameworks such as Spring, Spring Boot, etc. easily. Before practicing advanced Java topics, make sure you have set up the development environment for the same.
Get into frameworks like Spring, Hibernate, Spring Boot
After finishing all the above-mentioned topics we will move on to the more advanced and best part of our learning journey, such as Spring Framework and Hibernate Framework. As a Java developer, Spring, and Hibernate are the most important frameworks including Spring Boot as well. Furthermore, most Java development companies develop web apps using the Spring framework, such as Spring MVC, Spring REST, Spring Boot, and Spring Cloud.
Start developing Projects on Microservices Architecture
As we know Microservices-based applications are in high demand these days, irrespective of the programming languages. They are becoming popular exponentially day by day. Many big companies in the industry are already using this concept and developers are also becoming well-versed in the same. So, if you want to remain at the top position in the profession, you will have to adapt yourself to learn the most popular and trending technologies & concepts accordingly.
Learn Design Principles & Design Patterns
Design Principles are general guidelines or best practices that are used to create software that is maintainable, reusable, and easy to understand. These principles help developers create code that is easy to modify and extend in the future. One of the most popular design principles in Java is the SOLID Principle.
Design Patterns are proven solutions to common problems that software developers encounter when creating software. These patterns are tried and tested solutions to recurring design problems that can help developers create code that is more flexible, scalable, and maintainable. Some of the most popular design patterns in Java are 23 GoF (Gang Of Four) Design Patterns.
Learn DevOps Practices & Tools
Learning Java and its frameworks are not sufficient to become a successful Java Developer. You should also learn the popular methodology of developing and delivering an application like DevOps. Many development companies are shifting to DevOps and adapting the use of continuous integration as deployment. There are lots of tools and principles to learn in DevOps.
Learn Repository System Tools like Git
A Repository System is an essential tool for managing code in software development. It helps ensure code quality, collaboration, and reliability and offers a platform for managing the entire software development lifecycle. There are various tools available for repository systems, such as Git, Subversion (SVN), Mercurial, Perforce, Apache Subversion Edge, etc. Git is the most popular among Java developers.
Conclusion
In conclusion, by following these steps, you can become an Expert Java developer. Remember to have patience and persistence in your learning, as it takes time to become proficient in any skill. With dedication, practice, and continuous learning, you can achieve success as a Java developer and contribute to the constantly growing world of technology.
