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

When writing a Java program, a class (or interface) is typically placed in a separate Java file, and the class name is the same as the file name (if the class is public, the class name must be the same as the file name; non-public, no mandatory requirement). If you want to put multiple Java classes in a Java file, you can have only one public class. If the following two classes are placed in the same file w

Before looking at the So today I found a time to check the details of the difference between the two, summed up in this blog, not only to facilitate their own review and learning, but also to enlighten others. 1, Concept: A class that is defined within a class, called a "nested class". Nested classes are divided into two types: static and not static. The latter has a special name called "Inner class". So from the concept, it can be seen that the n

Note One: You can use the member methods and member variables of the outer class at will in the inner class.　 　It is well known that when you define a member method or member variable, you can add some permissions to the modifier to prevent other classes from accessing it. If you precede a member variable or a member method with the Private keyword, other classes cannot call member methods or member variabl

Entity classes are a concept that is widely used in Java software development. But there is little on the web to tell exactly what it is. In this issue I am going to talk about what is an entity class.First, the intuitive look:An entity class is a class that has a set and get methods. Entity classes are often associated with databases and the like (so-called persistent layer data). This connection is establ

Nested classes and internal classes are used extensively in Java, and to avoid being difficult to understand, here are a few small examples of how to use them. The structure of nested classes and inner classes such asStatic Nested ClassesA static nested class, which is a nested class declared outside of a class, c
