Hello devs, I am very excited to announce that I got my first sale this week. If you follow me on my blog Javarevisited (javarevisited.blogspot.com/) or read my article then you may know that I have been writing Java articles for the last 10 years. 

While I have been blogging for the last 10 years, I have never really sold anything, didn't have any book, course, or digital product. Finally, now I have my book ---[**Grokking the Java interview**](https://gumroad.com/l/QqjGH) on pre-sale on @Gumroad and got my first sale (pre-order).

Cracking Java Interview is not easy and one of the main reasons for that is Java is very vast. There are a lot of concepts and APIs to master to become a decent Java developer.

Many people who are good at general topics like [Data Structure and Algorithms](https://medium.com/javarevisited/7-best-courses-to-learn-data-structure-and-algorithms-d5379ae2588), [System Design](https://medium.com/javarevisited/10-best-system-design-courses-for-coding-interviews-949fd029ce65), [SQL and Database](https://medium.com/hackernoon/top-5-sql-and-database-courses-to-learn-online-48424533ac61) fail to crack the Java interview because they don't spend time to learn the Core Java concepts and essential APIs and packages like Java Collection Framework, Multithreading, JVM Internals, [JDBC](https://javarevisited.blogspot.com/2020/05/10-jdbctemplate-examples-in-spring.html), [Design Patterns](https://medium.com/javarevisited/7-best-online-courses-to-learn-object-oriented-design-pattern-in-java-749b6399af59), and [Object-Oriented Programming](https://medium.com/javarevisited/my-favorite-courses-to-learn-object-oriented-programming-and-design-in-2019-197bab351733).

This book aims to fill that gap and introduce you to classical Java interview questions from these topics. The book is a compilation of my best Java interview articles which are read by millions of developers. 

By going through these questions and topics you will not only expand your knowledge but also get ready for your next Java interview.

If you are preparing for Java interviews then I highly recommend you to go through these questions before your [telephonic](https://www.java67.com/2015/03/top-40-core-java-interview-questions-answers-telephonic-round.html) or [face-to-face](https://javarevisited.blogspot.com/2015/10/133-java-interview-questions-answers-from-last-5-years.html) interviews, you will not only gain confidence and knowledge to answer the question but also learn how to drive Java interview in your favor.

This is the single most important tip I can give you as a Java developer. Always, remember, your answers drive interviews, and these questions will show you how to drive the Interviewer to your strong areas.

If you are interested in the book you can pre-order for a special price of **$9.9** on Gumroad -  [**Grokking the Java Interview**](https://gumroad.com/l/QqjGH)

I owe a big thanks to the Dev community and all of you, my readers both on Twitter and here for inspiration, and Daniel Vassallo in particular whose [**Everyone Can Build a Twitter Audience**](https://gumroad.com/a/703100019/PBkrO) course and tweets inspired me to work towards creating my own book.

The big takeaway from this success is that you should create your own product as soon as possible, you don't need to wait for 10 years like I did but you should better start creating your own course and book right now. There is no better way to build your audience than by creating your own products.
