Course Introduction："Comprehensive Analysis of Java Annotations" is an important online Java tutorial. In project development, annotations are used everywhere. The use of annotations simplifies the code and reduces the programmer's workload. This course leads students to have a comprehensive understanding of Java annotations, including why annotations are used, common annotations in Java, classification of annotations and how to customize annotations. Finally, a practical case is used to demonstrate the application of annotations in actual projects.

Course Introduction：Introduction to the analysis of the implementation principle of MySQL lock: In the environment of concurrent access to the database, in order to ensure the integrity and consistency of the data, the database system needs to implement a lock mechanism. The lock mechanism ensures that different transactions can access and modify data in an orderly manner by restricting access to shared resources. As a commonly used relational database, MySQL also provides a variety of lock mechanisms to deal with concurrent access issues. This article will analyze the implementation principles of MySQL locks and provide specific code examples. Classification of MySQL locks in MySQL

Course Introduction：In the Go language, DNS resolution is usually implemented through functions in the net package. When performing DNS resolution, the Go language uses an asynchronous mechanism to ensure that the program will not be blocked while performing DNS resolution, thus improving the efficiency and performance of the program. In this article, we will explore the asynchronous mechanism of DNS resolution in Go language in detail and provide specific code examples. In the Go language, use the ResolveIPAddr and LookupIP functions in the net package for DNS resolution. Resolve

Course Introduction：Analysis of the principles of JAVA core reflection mechanism and introduction to code examples. In Java programming, the reflection mechanism is a very powerful feature. It allows us to check the information of classes, interfaces, methods and properties at runtime, and even modify the class at runtime. structure. This article will delve into the principles of Java's core reflection mechanism and explain its usage and usage scenarios in detail through code examples. The principle of reflection mechanism Java's reflection mechanism is implemented through classes under the java.lang.reflect package. It allows the program to run

Course Introduction：MySQL database automatic submission mechanism analysis MySQL is a commonly used open source relational database management system. It uses a method called an automatic submission mechanism to process transactions. In MySQL, the automatic submission mechanism is turned on by default, which means that each SQL statement will be executed immediately and submitted to the database, causing irreversible effects. Understanding MySQL's automatic commit mechanism is very important for developers because it directly affects transaction control and data integrity. automatic submission mechanism

Course Introduction：What are the mechanisms of the songtide resonance circuit? The Tide Resonance Loop mechanism is a special skill mechanism, because this mechanism can improve one's combat capabilities. Many friends still don’t know what the mechanisms of the Ming Tide Resonance Loop are. The following is an analysis of the Ming Tide Resonance Loop mechanism. Let’s take a look at it together. What are the mechanisms of the Sing Tide Resonance Circuit? Each resonator has its own unique resonance circuit. Proper use of this mechanism can effectively improve combat capabilities. The release mechanism of special skills can be viewed in "Resonance Loop". Taking Kakaro as an example: Release normal attacks/skills to hit the enemy to obtain [Killing Intent] (which can be understood as special skill charging). The resonance loop (special skill) is fully charged. /Not full diagram:
