Hi,
I am preparing for 1ZO-819 exam and I am a bit confused when it comes to Concurrency.
The official exam topic page vaguely describes it as follows:
1. Create worker threads using Runnable and Callable, and manage concurrency using an ExecutorService and java.util.concurrent API
2. Develop thread-safe code, using different locking mechanisms and java.util.concurrent API
For preparation I am following
Java SE 11 Developer 1Z0-819 OCP Course - Part 1 & 2 and also Sybex 819 practice tests book.
I understand all the concepts discussed in the course and I've also completed and understood the questions from the book as well.
But I wanted to know will this be enough? The book has only 30 questions on Concurrency which confuses me as its a topic of great importance (from what I've read).
Kindly let me know your thoughts and also if you feel there is some other way that will be much more suited.
Thanks
