Extreme Java - Concurrency Performance for Java 8 (2016 Edition)

Java Concurrency in Practice for Java 8

   Watch Promo   Enroll in Course

This course could be your most productive learning experience ever! It is aimed at the busy Java professional who wants to quickly learn and apply new essentials on core Java topics. All topics have been thoroughly researched by Dr Heinz Kabutz, famous in over 145 countries for his Java Specialists' Newsletter .

Extreme Java - Concurrency Performance is only concurrency course endorsed by Brian Goetz, author of the best-seller Java Concurrency in Practice. Our course is loosely based on Goetz' excellent book, but adapted for modern Java.

During the course we use the new Java 8 syntax for lambdas and streams, making the code more readable. You will learn about threading, performance, compare-and-swap non-blocking constructs, garbage collectors and many other topics that you will be able to quickly apply in your own work. We will also cover all relevant constructs found in Java 8, such as StampedLock, LongAdder, parallel streams and many more. As a side effect, you will get familiar with Java 8 lambdas and streams.

Please look at the outline to see all the topics covered. During the training, you will always get a chance to try out what you have learned in carefully thought out exercises. This will help you understand and quickly internalize what you have just learned.

Is this course for you?

Students who have successfully completed this course, can expect the following outcomes:

  1. Throughout the course, we use the new Java 8 syntax. The first outcome would thus be an understanding of how lambdas and streams work in Java 8.
  2. Students gain a good understanding of why threads are important and what the risks are. They learn how to share objects safely, including visibility concerns. They also master safety techniques of thread confinement, stack confinement and object confinement. Through this, they learn how to design a thread-safe class.
  3. They will know the difference between a synchronized and a concurrent collection and when to use which one. This is particularly important to be able to write high-performance code that scales well.
  4. They would understand how a blocking queue can be used to build producer consumer systems and what the various blocking queues are in Java.
  5. They would know how Semaphore, CountDownLatch and Phaser works.
  6. Students would learn how to use the thread pool executors to run tasks asynchronously. They would also learn how to configure these, including how to cope with an unexpected number of tasks and how the various settings interact.
  7. They will learn how to break up a large tasks into smaller tasks by choosing good task boundaries, resulting in tasks that are homogeneous and independent.
  8. They would learn how to cleanly cancel tasks that have been started by using interruptions and volatile boolean fields.
  9. Students would learn how the Fork/Join Pool works by comparing it to a normal single-threaded recursive algorithm. They will also get an opportunity to refactor a piece of Fork/Join Code to use parallel streams instead, in order to see how Java 8 can make coding a bit easier.
  10. Students would know how to detect and solve liveness issues, such as deadlock, livelock and contention.
  11. They would also know how to find and solve performance bottlenecks, especially in threaded code.
  12. They would know how ReentrantLock, ReentrantReadWriteLock and the new Java 8 StampedLock work and how we can use that to write efficient code using optimistic techniques.
  13. They would know how to write their own synchronizers when needed, by creating state-dependent classes.
  14. Students would understand what atomic classes are and know techniques to use them to build efficient non-blocking classes that offer better performance under contention.
  15. They would understand the most common garbage collection algorithms: throughput, concurrent and G1 and also how to tune each one to give best performance.
  16. They would know how to discover performance bottlenecks in an application and also how to solve these. They would also learn how profilers can be used to find bottlenecks and the role of microbenchmarks in confirming these.
  17. Throughout the course, a strong emphasis is placed on the practical application of learning. Each student needs to complete a set of exercises to demonstrate that they have understood the material.

After successful completion of the course and all the exercises, students qualify for a "course completion certificate" similar to the following:

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.
Where do I enter my company details?
We usually suggest that you enter them in the "Full Name" field, together with your name and your company VAT number. Be sure to also enter the VAT number in the appropriate field if your company is registered in the EU. We can accept direct payments and issue company invoices for orders larger than $1500. Please contact us for direct payment.
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.
What if I am unhappy with the course?
We would never want you to be unhappy! If you are unsatisfied with your purchase, contact us in the first 30 days and we will give you a full refund and deregister you from the course.
When does the course start and finish?
The course starts now and never ends! It is a completely self-paced online course - you decide when you start and when you finish. We do recommend putting time aside and setting goals to complete the course.
Can I watch the course offline during my commute?
Teachable have an iOS app that lets you watch offline. Android is not supported unfortunately.
