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.

There are three ways to change the default terminal in VSCode: setting through a graphical interface, editing settings.json file, and temporary switching. First, open the settings interface and search for "terminalintegratedshell" and select the terminal path of the corresponding system; secondly, advanced users can edit settings.json to add "terminal.integrated.shell.windows" or "terminal.integrated.shell.osx" fields and escape the path correctly; finally, you can enter "Terminal:SelectD through the command panel

When the "Timedoutwaitingforthedebuggertoattach" issue occurs, it is usually because the connection is not established correctly in the debugging process. 1. Check whether the launch.json configuration is correct, ensure that the request type is launch or attach and there is no spelling error; 2. Confirm whether the debugger is waiting for the debugger to connect, and add debugpy.wait_for_attach() and other mechanisms; 3. Check whether the port is occupied or firewall restricted, and replace the port or close the occupied process if necessary; 4. Confirm that the port mapping and access permissions are configured correctly in a remote or container environment; 5. Update VSCode, plug-in and debug library versions to solve potential

There are two ways to set environment variables for VSCode terminals on Linux: one is to use the terminal.integrated.env.linux configuration item to define variables that are only used by VSCode; the other is to modify the shell configuration file to take effect globally. 1. In VSCode, add variables such as "MY_VAR":"my_value" by setting the terminal.integrated.env.linux field. This method only affects the VSCode terminal; 2. Modify shell configuration files such as ~/.bashrc or ~/.zshrc and add exportMY

VSCode workspace is a .code-workspace file that saves project-specific configurations. 1. It supports multi-root directory, debug configuration, shortcut key settings and extension recommendations, and is suitable for managing different needs of multiple projects. 2. The main scenarios include multi-project collaboration, customized development environment and team sharing configuration. 3. The creation method is to save the configuration through the menu File>SaveWorkspaceAs.... 4. Notes include distinguishing between .code-workspace and .vscode/settings.json, using relative paths, and avoiding storing sensitive information.
