Call conn.setAutoCommit(false) to start the transaction; 2. Execute multiple SQL operations, such as INSERT and UPDATE; 3. Call conn.commit() if all operations are successful, and call conn.rollback() if an exception occurs to ensure data consistency; at the same time, try-with-resources should be used to manage resources, properly handle exceptions and close connections to avoid connection leakage; in addition, it is recommended to use connection pools and set save points to achieve partial rollback, and keep transactions as short as possible to improve performance.

Use a package manager, such as apt, dnf or pacman, and then execute the install command after updating the source, such as sudoaptininstallcurl; 2. For .deb or .rpm files, use dpkg or rpm commands to install, and repair dependencies when needed; 3. Use snap or flatpak to install applications across platforms, such as sudosnapinstall software name, which is suitable for users who are pursuing version updates. It is recommended to use the system's own package manager for better compatibility and performance.
