The Finest 5 Courses on Java Multithreading and Concurrency for Seasoned Programmers in 2024The Finest 5 Courses on Java Multithreading and Concurrency for Seasoned Programmers in 2024

Multithreading and concurrency are essential skills for experienced Java developers to master. Companies frequently test and assess Java developers on their knowledge of
threads, parallelism, synchronization, thread safety, deadlock avoidance, and other
complex concurrency topics during interviews.

Having strong multithreading skills makes you stand out as a Java developer. It shows you can design and build fast Java applications. They use modern multi-core processors well by using concurrent execution

However, multithreading is notoriously tricky to get right. Threads accessing shared data can clash. This can cause race conditions, deadlocks, and non-deterministic behaviour. But, this only happens if you don’t fully grasp basic concurrency concepts .

In this guide, I will share the top 5 online courses. They will take your multithreading and concurrency skills to an expert level. This is for Java developers in 2024.

Unmatched learning possibilities from well-known professionals and authority in the industry are provided by these courses. They will provide you with in-depth knowledge and useful tips so you can build reliable, effective multithreaded Java programmes.

The Importance of Multithreading and Concurrency Skills

Multithreading and concurrency are critical skills for Java developers to master. There are several key reasons:

  • Enables applications to perform multiple tasks simultaneously, improving speed and responsiveness. The app doesn’t freeze up when doing long operations.
  • Allows Java apps to handle many user requests concurrently. This helps applications scale up.
  • Utilizes modern multi-core CPUs efficiently by spreading work across threads.
  • Permits background timed or asynchronous tasks to execute while main application logic runs.
  • Multithreading questions often come up in Java job interviews. Companies want to ensure candidates have these skills.

When evaluating multithreading courses, experienced Java devs should look for a few key things:

  • Simple, beginner-friendly explanations of concepts. Complex topics made easy to grasp.
  • Real code examples and hands-on exercises to practice multithreading.
  • Visual aids like diagrams and videos to demonstrate core ideas.
  • Coverage of both multithreading fundamentals and advanced techniques.

With strong multithreading skills, Java developers can build more responsive, scalable applications. These skills open up new job opportunities as well.

Choosing the Best Java Multithreading Course

Learning Java multithreading and concurrency can be tricky. Here are some tips to help you choose a good Java multithreading course:

Look for an instructor who really knows their stuff. Find a course taught by an expert who has lots of experience with Java multithreading in real world programs.

Make sure the course covers all the basics. Thread safety, synchronization, shared data – these key concepts need to be explained clearly. The course should also cover more advanced topics like non-blocking code.

Hands-on learning is a must. You need to write real Java code and do exercises to get comfortable with concurrency. Avoid courses that just lecture without code examples.

Choose a course that focuses on Java 8 and newer. The modern concurrency APIs like streams and executors are important to learn. Older courses using outdated APIs won’t help much.

Interaction helps learning. Look for courses with quizzes, assessments and other ways to test your understanding.

The course should teach practical skills you can apply on the job. Avoid overly theoretical courses that don’t connect to real world programming.

Overall, find a course that provides a solid foundation and teaches real coding skills. With the right instruction, you’ll be multithreading like a pro in no time.

2. Concurrency in Go

Instructors: Katharine Cox-Buday, William Kennedy

Platform: O’Reilly

This unique course strengthens your concurrency skills through mastering concurrency in Golang. It’s taught by William Kennedy and Katherine Cox-Buday, renowned Go experts.

The decision to teach concurrency using Go instead of Java provides huge advantages. You gain fresh perspective and reinforce your existing Java knowledge by learning Golang’s concurrency model which differs from Java’s.

For example, Go uses message passing while Java uses shared memory for communication between threads. You’ll learn clever techniques like goroutine wrapping that help avoid issues like deadlock.

The curriculum covers both concurrency fundamentals like mutexes alongside advanced material like patterns and best practices tailored to Go’s concurrent programming model. Highly-rated with stellar reviews.

Key Details:

  • 3.5 hours on-demand video
  • Fundamentals like communication, synchronization
  • Advanced patterns and best practices
  • Taught through concrete Go code examples
  • Interactive quizzes reinforce key learnings
  • 4.8/5 star rating (highly rated course)
