Concurrency, Multithreading and Parallel Computing in Java

• Understand basic concurrency
• Understand the basics of multithreading
• Understand parallel processing
• Able to use the concepts in real life scenarios
• Understand concurrent collections
• Understand synchronization and locking
• Understand the Fork-Join Framework
• Understand Stream API

This course is about the basics of multithreading and concurrent programming with some parallel concepts. In the 21st century this topic is becoming more and more popular with the advent of Big Data and Machine Learning. We will consider the low level concepts such as threads,synchronization andlocks. The second chapter will be about concurrent library: of course there are built in classes and interfaces that we can use when implementing multithreaded applications. Then we develop little programs as show-cases for multithreading: the dining-philosopher problem and the students in library simulation. Last chapter is about parallel computing and MapReduce.
