java - I deleted the svn code locally and re-imported it from the remote repository. It prompted me that it already exists.

Question

Answer 1

Try changing the folder

Answer 2

Is it imported to the same address and the previous .svn (hidden file by default) is not deleted?

Answer 3

Same as above, the file downloaded from svn will generate a .svn file in the directory where you downloaded it. You need to delete that file.
You can also re-download the file to another directory

Answer 4

Same as above, just delete the .svn folder
