How to move and overwrite all files from one directory to another?

Question

I know about the Methods in FileUtils , but the FileUtils won't overwrite.

Also in Files.move("", "", StandardCopyOption.REPLACE_EXISTING) when the file exists and it's not empty, then the following exception is thrown: java.nio.file.DirectoryNotEmptyException

Sample:

/file1/test1
/file2/test1

How do I merge, move, and overwrite (such as move in windows), /file1/test1 to /file2/test1 ?

has java function for this job? I want don't write any method

Answer 1

You could do naive approach with standard java util functions, and nit with Files. First, write a method, what will move and overwrite one file. Before moving, check if the file with this name is is the target folder and delete it, what is simpler, (or open end overwrite content, what is unnecessary complicated). Then, get the list of all files in source folder and apply the method above in the loop.
