Steps to Become a Java Developer in 8 Weeks

Understand Object-Oriented Principles

To become an excellent Java developer, you must have a strong understanding of object-oriented principles. Besides acquiring a good knowledge of the theory, you must also learn to apply these principles while developing an application. You must practice and learn inheritance, design patterns, and object modeling to lay a strong foundation.

Master the Core Java SE

Start learning the fundamentals and keep writing small programs to improve your understanding. No matter how quickly you learn the definitions, if you do not understand the language construct and core API, you will never be able to write crisp code. You must possess a good understanding of general-purpose APIs like Java.lang, I/O exceptions, threads, etc.

Keep Practising as Much as Possible

You might have heard the saying that practice makes a man perfect. A code may look easy when you look at it, but you may face several errors while writing it yourself. The challenging part of the problem always lies in the implementation of your idea or approach. Keep practising to design some best practices.

Explore New Technology Trends

Software industry trends change at a rapid pace. By the time you learn about one technology, it comes with the risk of becoming obsolete as some new trend would have gained popularity. Hence, the solution you are trying to achieve with the old framework is the selling point of the new framework. It is crucial to keep an eye on emerging trends.
