The only guide you’ll need on concurrency & multithreading for senior engineers. Pressure test your skills with real-world practice problems from top companies.

Concurrency in Java is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage. This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors and Deferred Callbacks in depth. It also builds simple and complete solutions to popular concurrency problems that can be asked about in interviews like the Reader-Writer Problem and the Dining Philosopher Problem. While prior knowledge of concurrency is not required to follow through with this course, familiarity with the very basics of concurrency would be helpful.

# Moore's Law

In this lesson, we'll cover a high-level overview of Moore's law to present a final motivation to the reader for writing multi-threaded applications and realize that concurrency is inevitable in the future of software.

[Gordon Moore](https://en.wikipedia.org/wiki/Gordon_Moore), co-founder of Intel, observed the number of transistors that can be packed into a given unit of space doubles about every two years and in turn the processing power of computers doubles and the cost halves. Moore's law is more of an observation than a law grounded in formal scientific research. It states that **the number of transistors per square inch on a chip will double every two years**. This exponential growth has been going on since the 70’s and is only now starting to slow down. The following graph shows the growth of the transistor count.
