3.2 Actor Examples - Concurrent Programming in Java
Parallel, Concurrent, and Distributed Programming in Java Specialization
This course teaches learners (industry professionals and students) the fundamental concepts of concurrent programming in the context of Java 8. Concurrent programming enables developers to efficiently and correctly mediate the use of shared resources in parallel programs. By the end of this course, you will learn how to use basic concurrency constructs in Java such as threads, locks, critical sections, atomic variables, isolation, actors, optimistic concurrency and concurrent collections, as well as their theoretical foundations (e.g., progress guarantees, deadlock, livelock, starvation, linearizability).

Why take this course?

• It is important for you to be aware of the theoretical foundations of concurrency to avoid common but subtle programming errors.
• Java 8 has modernized many of the concurrency constructs since the early days of threads and locks.
• During the course, you will have online access to the instructor and mentors to get individualized answers to your questions posted on the forums.
• Each of the four modules in the course includes an assigned mini-project that will provide you with the necessary hands-on experience to use the concepts learned in the course on your own, after the course ends.

The desired learning outcomes of this course are as follows:

• Concurrency theory: progress guarantees, deadlock, livelock, starvation, linearizability
• Use of threads and structured/unstructured locks in Java
• Atomic variables and isolation
• Optimistic concurrency and concurrent collections in Java (e.g., concurrent queues, concurrent hashmaps)
• Actor model in Java

Mastery of these concepts will enable you to immediately apply them in the context of concurrent Java programs, and will also help you master other concurrent programming system that you may encounter in the future (e.g., POSIX threads, .NET threads).

Very well structured and presented course! Very useful material with good relevant examples! Thank you, Prof. Sarkar for this Concurrent Programming in Java course!,Awesome course, it nudges students in right directions, provides them with solid fundamentals and encourages them to deep dive more into topics. Thanks a lot!
In this module, we will learn another high-level approach to concurrent programming called the Actor model. A major difference between the Actor model and the Isolated Sections model is that there are no data races possible in the Actor model because it does not allow for any form of shared variables. However, as in all concurrent programming models, higher-level forms of nondeterminism are still possible in the Actor model due to an inherent asynchrony in the order in which messages may be delivered. We will study multiple examples of concurrency using the Actor model, including the classical Sieve of Eratosthenes algorithm to generate prime numbers, as well as producer-consumer patterns with both unbounded and bounded buffers.
