How to restore the idea code formatting after it has been formatted.

Most IDEs have a code formatting feature that can be accessed by pressing a shortcut key (typically Ctrl + Shift + F) or selecting the formatting option from the menu. These IDEs also usually automatically save the formatted code, allowing you to revert to the previous state at any time. If automatic saving is not enabled, you can use version control systems (such as Git) to compare and recover the code before the modifications. Additionally, online code formatting tools can be used to paste the formatted code and then choose to restore it to its original format.
