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.

Java Multithreading for Senior Engineering Interviews

# Creating Threads
To use threads, we need to first create them. In the Java language framework, there are multiple ways of setting up threads.

# Runnable Interface
When we create a thread, we need to provide the created thread code to execute, or in other words we need to tell the thread what *task* to execute. The code can be provided as an object of a class that implements the [Runnable](https://docs.oracle.com/javase/8/docs/api/java/lang/Runnable.html) interface. As the name implies, the interface forces the implementing class to provide a run method which in turn is invoked by the thread when it starts.

The runnable interface is the basic abstraction to represent a logical task in Java.

This lesson discusses how threads can be created in Java.
