Course Introduction：The data visualization project uses the most popular chart engine ECharts to display all aspects of data that need to be presented in the e-commerce platform. Used to analyze the operation of e-commerce platforms in more detail in order to make correct decisions. The front-end of this project uses the Vue technology stack, the back-end uses the Koa2 framework, and the front-end and back-end data interaction uses WebSocket to ensure the real-time nature of the data. The project also supports theme switching to display cool chart effects. It also supports switching between large and small screens, ensuring that charts are presented on different screens.

Course Introduction：A file is a collection of data stored on disk with a specific name and directory path. When a file is opened for reading or writing, it becomes a stream. Stream types include: byte streams - including Stream, FileStream, MemoryStream and BufferedStream. Character streams - including Textreader-TextWriter, StreamReader, StraemWriter and other streams. Classes for byte streams treat the data in the stream as bytes. The Stream class is the base class for other byte stream classes. The following are its properties: CanRead - whether the stream supports reading CanWrite - whether the stream supports writing Length - the length of the stream S

Course Introduction：Introduction to IO 1 Stream Before learning the IO stream, the first concept we need to learn is the Stream stream. In order to facilitate understanding, we can abstract the read and write operations of data into data flowing in a "pipeline", but please note: 1. The stream can only be Directional flow 2. The input stream is used to read → in3. The output stream is used to write → out4. Data can only be read and written sequentially once from beginning to end, so thinking from the perspective of a program, In/out is the input relative to the program ( The process of reading)/output (writing). 2. The inheritance structure of IO stream In Java, according to the different data units processed, the stream can be divided into byte stream and character stream. Byte stream: for binary file character stream: for Text files are then combined to correspond

Course Introduction：Process HTML In today's digital age, web pages have become one of the main ways for corporate promotion and communication. The presentation of processes is an important part of a corporate web page, which can be used to introduce information such as the operation methods and work processes of a company or organization. In this article, we’ll take a closer look at flow HTML and learn how to create and apply flow diagrams to optimize your web pages. 1. What is process HTML? Process HTML is a technique for creating flowcharts using HTML markup. It aims to make the process design of web pages simpler and easier to understand. Process HTML not only allows the use of

Course Introduction：Parallel streams and sequential streams in Java As computer hardware performance continues to improve, more and more applications need to process large amounts of data. The traditional sequential flow method is often inefficient when processing big data. At this time, parallel streaming becomes an option to improve program efficiency. In Java 8, the concept of parallel streams was introduced, allowing Java programs to better take advantage of multi-core CPUs, thereby improving the efficiency of data processing. This article will take an in-depth look at parallel and sequential streams in Java. 1. Sequential flow in Java,
