If you are a Java developer and looking for some awesome resources e.g. books and courses to improve your multi-threading and concurrency skills in Java then you have come to the right place. In the past, I have shared
books and
tutorials on Java Concurrency and Multithreading and in this article, I am going to talk about some of the best free and paid course to learn multi-threading and concurrency in Java. You can join these free courses to improve your understanding of Java Concurrency and Multithreading. It's one of the most important skills for Java developers as almost all the companies who interviews Java developers pay particular attention to his knowledge and experience in this area.

How to avoid deadlock in Java? is one of the popular
Java interview question and flavor of the season for multi-threading, asked mostly at a senior level with lots of follow up questions. Even though question looks very basic but most of the Java developers get stuck once you start going deep.



Interview questions start with "
What is a deadlock?"

The answer is simple when two or more threads are waiting for each other to release the resource they need (lock) and get stuck for infinite time, the situation is called deadlock. It will only happen in case of
multitasking or
multi-threading.

Multi-threading and concurrency questions are an essential part of any Java interview. If you are going for any Java interview on any Investment bank e.g. Barclays, Citibank, Morgan Stanley etc for Cash Equities Front Office Java Developer position, you can expect a lot of multi-threading interview questions on your way. Multi-threading and concurrency are favorite topics on Investment banking interviews,  especially on electronic trading development jobs and they grill candidate on many
tricky java thread interview questions. They just want to ensure that the guy has solid knowledge of multi-threading and concurrent programming in Java because most of them are in the business of performance which provides them a competitive advantage and it's hard to write correct and robust concurrent code.
