Java Multithreading and Parallel Programming Masterclass - Shift Data Between Threads with Exchangers

This lecture covers the concept of an exchanger in Java, a synchronization primitive used to exchange data between two threads. The exchanger is similar to a barrier but focuses on data exchange. It uses a simple method called 'exchange' that takes and returns an object of a specified generic type, throwing an interrupted exception if necessary. The lecture explains how two threads interact using the exchanger, the importance of having pairs of threads to avoid blocking, and provides a practical example of implementing an exchanger in Java.

Describe the process of data exchange between two threads using an exchanger.

What precautions should be taken when using an exchanger with multiple threads?
