This weekend, I accidentally turned to the batch renaming gadget written in Java in 2004 at home, and today I will share it with you Joy. I remember that there was no IDE at that time, so I wrote it in Notepad, wrote a paragraph and ran it with the cmd command to see the effect, and slowly debugged it. After all these years, Java skills have been completely forgotten. If you are interested, you can copy the code to run it, select the corresponding folder or enter the path to name all the files in the folder through certain rules, and support the function of restoring after name change.
Run the code
1. Create a new text file, rename it to PLGM.java Copy the code below to save
2. cmd Window Input:
javac PLGM.java
java PLGM Run the results
Concrete code
