One of the defining features of the Java environment is its built-in support forthreads. Threads let an application perform multiple activities simultaneously. When used properly, threads let the application's user interface remain responsive while it performs lengthy operations like network communication...
Java In Depth: Using threads with collections, part 2McManis, Chuck
The Java synchronized keywordThe Java synchronized keyword is fundamental for programs that use multiple threads. Ordinarily, if you have multiple threads all accessing the same data concurrently, there is risk of a so-called race condition. For example, one thread could see data in an ...
The wait/notify mechanism also provides us no means of imposing fairness: that is, if two threads want to add a logging while the list is locked (because a line is being logged from it), which line gets logged first is essentially random. In the case of logging, this may not seem ...

Though the HashMap class is not thread-safe, the returned instan- tiation is thread-safe, since this wrapping technique delegates the method calls such as HashMap.get() and HashMap.put() using synchronized blocks, as shown in Figure 2. Then the Thread.start() method launches two threads....
In this post, I have introduced you to thread communication in Java using Lock and condition. A thread can acquire the lock, and check if the condition is met. If the condition is not met, a call toawaiton the condition instance releases the lock for other threads. A thread can notify...
