Basic concepts Iterator mode, also known as cursor mode, is the behavior mode of objects.Iterator patterns can sequentially access elements in a cluster without exposing the internal representation of the cluster. 2. Pattern Diagram 3. Core Role Iterat ...

I. Introduction of Prototype Patterns Prototype pattern is an object creation pattern. It uses the method of replicating prototype objects to create instances of objects. Instances created using prototype patterns have the same data as prototypes. The characteristics of the prototype model: 1. Create the target object by the prototype ob ...

The ThreadGroup class is used in Java to represent a thread group, representing a set of threads, which can be managed by a group of threads and thread groups. Threads can be attributed to a thread group, which can have thread objects, thread groups and threads. Such an organization structure is somewhat similar to that of a tree, as shown in t ...

Summary of Load Balancing Algorithms Stochastic algorithm Firstly, the server is put into an array or a list, and a subscript within the valid range of the array is obtained through the random algorithm of JDK. According to the random subscript, the corresponding server is accessed. From the theory of probability and statistics, we can know tha ...

Proxy is a structural design model that mainly solves the problems caused by direct object access. Proxy is divided into static proxy and dynamic proxy (JDK proxy and CGLIB proxy).Static proxy: Proxy classes created by programs, or specific tool classes, are often used in normal development. This kind of proxy mode usually generates correspondi ...
