8 Best and Free Java Multithreading and Concurrency Courses for Beginners in 2022

Hello guys, if you want to learn multithreading and concurrency in Java and looking for the best learning material like books, tutorials, and online courses then you have come to the right place. Earlier, I have shared the best Core Java courses and best data structure and algorithm courses and in this article, I am going to share the best online courses to learn Multithreading in Java. These courses are curated from the best online learning websites like Udemy, Pluralsight, and Coursera and will teach you Java Multithreading from scratch. But, before we get to the best courses that you can use to learn more about multithreading in Java, let me tell you what multithreading exactly is.  

Multithreading is basically a feature in Java that allows the concurrent execution of one or more of a program for maximum utilization of CPU. Each part of a program in Java is called a thread. This means that these threads can be seen as a kind of process within a process. And threads can be created by either extending the thread class or implementing the runnable interface.

The process of multithreading is very useful in Java as it is more efficient than multiprocessing and because threads use a shared memory area. This means that threads don't allocate separate memory areas and this saves memory. Also, context-switching between the threads takes less time than the process.

Multithreading in Java doesn't block the user as threads are independent and users can separate operations at the same time. Users can also save time by performing many operations together. And since threads are independent, it doesn't affect other threads if there is an exception in a single thread.
