Binary and Counting Semaphores in Java

Binary and counting semaphores allow threads to signal each other to share data safely. Java has built in abilities to do use both of these techniques. Any object can be a binary semaphore and we can use that to signal binary conditions like "Queue full". Using this feature requires synchronizing on the object and there is a risk of spurious wake up that we have to be careful about. For counting semaphores, Java gives us the Semaphore class that allows much richer signaling capabilities. In this video, I show both of those techniques and how we combine them with synchronize blocks to prevent race conditions in various Producer/Consumer scenarios.

We cover introductions to programming in C and Java. But I also have lots of software and computer engineering topics like PIC programming, advanced programming techniques, and things that distinguish good code from code that works.
