Mastering Threads (Early 2019 Edition)

Let's write a ThreadPool together. First exercise. A sea of scared faces. Is the teacher kidding?

"Mastering Threads" is an intense one day course that starts with the basics of threads. We then look at laws that help us to write correct threaded code. We then go to higher-level constructs that make threading much easier to use. We ends with diagnosing race conditions and deadlocks.

Each section ends with exercises that you can solve to hone your skills as a Java programmers. Some of these exercises (write a ThreadPool) has challenged hundreds of Java programmers. In solving these, we learn how inter-thread communication works. We learn how to keep our classes thread-safe. We also learn about thread states.

We have a detailed walkthrough for each exercise. Furthermore, students can submit their solved exercises to heinz@javaspecialists.eu for marking. This helps in the learning aspect as they get feedback from the instructor.

We use OpenJDK 11 for this course, taking full advantage of the new var syntax. However, programmers with Java 6 or 7 knowledge will also be able to follow.

We are selective on what we cover in this. Our intention was to create a short course that will teach you enough to help you in your every day work. Job interview questions on concurrency should not be hard after this. "Mastering Threads" is an introductory course on the topic of concurrency. For a more thorough exposition, please consider "Extreme Java - Concurrency Performance".

Diese Schulung gibt es auch auf Deutsch.

Frequently Asked Questions


How long do I have access to a fully paid course?
How does lifetime access sound? After enrolling, you have unlimited access to this course for as long as you like - across any and all devices you own. Furthermore, if we move to another platform, we will offer you a free transfer of your account for all the courses that you have purchased.
What is the difference between a subscription, paying in installments and an outright purchase?
With a subscription, you never own the rights to the material. If your card is declined or you cancel your subscription, you lose access to the course. The money you have paid so far is lost. Paying in installments is a bit better. You pay for 5 or 10 months and then once you have completed your installments you have lifetime access to the course. The safest is an outright purchase, where you pay the entire course in one amount. There is no risk of losing access.
Can I pay via PayPal?
Yes, you can for outright purchases, but not for recurring payments such as paying by installments or subscriptions.
Can I get an EU VAT Invoice?
Absolutely. First off, be sure to enter the VAT number in the appropriate field during the payment process. Then contact us for an EU VAT Invoice. Please tell us the receipt number for which you need the invoice.
May I share my login details with my colleagues?
Unfortunately not. The terms of usage are for a single license. Teachable tracks your progress through the curriculum, so you won't know how much you have watched. We offer a 50% discount on 15 licenses or more by one company. Please contact us for bulk licensing.
May we use the course for running in-house courses?
You may, as long as each of the students in the class has a valid license for that course. For example, a lot of companies run lunch time Design Patterns study groups using our material. This is an effective way to learn. Please contact us for bulk licensing.
