In Chapter 2, Basic Thread Synchronization, you learned the concepts of synchronization and critical sections. Basically, we talk about synchronization when more than one concurrent task shares a resource, for example, an object or an attribute of an object. The blocks of code that access this shared resource are called critical sections.
If you don't use appropriate mechanisms, you might have incorrect results, data inconsistencies, or error conditions. Therefore, we have to adopt one of the synchronization mechanisms provided by the Java language to avoid these problems.
Chapter 2, Basic Thread Synchronization, taught you about the following basic synchronization mechanisms:
- The synchronized keyword
- The Lock interface and its implementation classes: ReentrantLock, ReentrantReadWriteLock.ReadLock, and ReentrantReadWriteLock.WriteLock
- The StampedLock class
In this chapter, you will learn how...
