The collections framework is a key component of Java. It provides an extensive number of interfaces and implementations, which allows us to create and manipulate different types of collections in a straightforward manner. Although using plain unsynchronized collections is simple overall, it can also become a daunting and error-prone process when working in multi-threaded environments (a.k.a. concurrent programming). Hence, the Java platform provides strong support for this scenario through different synchronization wrappers implemented within the Collections class. These wrappers make it easy to create synchronized views of the supplied collections by means of several static factory methods. In this tutorial, we’ll take a deep dive into these static synchronization wrappers. Also, we’ll highlight the difference between synchronized collections and concurrent collections. The first synchronization wrapper that we’ll cover in this round-up is the synchronizedCollection() method. As the n
