To set the default formatting tool in VSCode, you must first install extensions of the corresponding language, such as Prettier, Black or ESLint. 1. Open the settings and search for "DefaultFormatter", edit the settings.json file to specify the default formatting tools for each language, such as using "esbenp.prettier-vscode" to handle JavaScript, and "ms-python.black-formatter" to handle Python. 2. Optional global settings, but it is recommended to configure them separately by language. 3. Enable "FormatonSave"

The best way to make batch modifications in VSCode is to use the Find and Replace feature. 1. Use "Find and Replace" in a single file: Press Ctrl H to open the panel, enter the search and replace content, and click "Replace" or "Replace All". 2. Search across multiple files: Press Ctrl Shift F to open the search tab, expand the replacement section, and select the replacement operation for a single file or entire project. 3. Use advanced options: such as case sensitivity, full word matching and regular expressions for more precise control, such as matching numbers with \d or using capture groups for complex replacements. This feature significantly improves code maintenance efficiency through fast and precise editing.

Viewing Git history in VSCode can be achieved through the built-in Git extension. The specific steps are as follows: 1. Open the Git sidebar on the left, view the list of recent submissions and select a specific submission; 2. View the file modified by the submission and line-by-line differences in the right panel, and right-click the file to perform restore changes and other operations; 3. Right-click the file in the editor and select "Open Timeline", and use the timeline view to view the historical change record of the file. These steps allow you to easily track project changes without relying on external tools.

The key steps in configuring the Java debugging environment on VSCode include: 1. Install JDK and verify; 2. Install JavaExtensionPack and DebuggerforJava plug-in; 3. Create and configure the launch.json file, specify mainClass and projectName; 4. Set up the correct project structure to ensure the source code path and compilation output are correct; 5. Use debugging techniques such as Watch, F8/F10/F11 shortcut keys and methods to deal with common problems such as class not found or JVM attachment failure.

To use VSCode for Java development, you need to install the necessary extensions, configure the JDK and set up the workspace. 1. Install JavaExtensionPack, including language support, debugging integration, build tools and code completion functions; optional JavaTestRunner or SpringBoot extension package. 2. Install at least JDK17 and verify through java-version and javac-version; set the JAVA_HOME environment variable, or switch multiple JDKs in the status bar at the bottom of VSCode. 3. After opening the project folder, make sure the project structure is correct and enable automatic saving, adjust the formatting rules, enable code checking, and configure the compilation task to optimize the opening.
