The previous chapter says that delegates are one of the most effective strategies for creating thread-safe classes by simply having existing thread-safe classes manage all the state. So this chapter is about how to use the Java Platform Class Library of the concurrent base building module?5.1 Synchronizing Container classesIncludes vectors and Hashtable, as well as some of the functionally similar

The interface class is not instantiated and requires one by one of all methods that implement the interface definition. Keyword interface implementsInterface interface is a rule that gives people inheritance with something that's kind of like abstract classThe method defined in the inside, but does not instantiate, but needs other classes to implements it, and must implement all the methods of the interface definition,In fact, the interface class is p

1.1 Definition of Cluster (collection) A cluster is a structured data type. Store data and provide data additions, deletions, and changes, as well as setting and returning operations for different attribute values of the cluster.Clusters are divided into two categories: linear and nonlinear clusters.A linear cluster is a list of elements in which the elements in the table are connected sequentially. (1, 2, 3, 4) the array in the computer world is a linear cluster.Non-linear clusters contai

Internal classes are defined in Wikipedia as: In object-oriented programming, an inner class (also called a nested Class) is a class that is declared in another class or interface. The inner class differs from the subclass (subclass). (Translator Note: the wiki annotations are incorrect, and the inner and nested classes are not identical, see below.) ）In Java, the above definition can be an example of the f
