I want to delete subfolders and its contents from a folder using Java.

For example:
Folder
|__Subfolder1 - a.txt
|__Subfolder2 - b.txt
|__Subfolder3 - c.txt

I need to delete content of subfolders and its contents using Java. But Folder(Parent) should not be deleted.
Please help me.

Class java.io.File has a delete() method which you can use to delete files and directories.

You'll have to first delete all files in the directory, and then the directory itself.

Thanks for the reply Jesper. I am using following snippet to delete contents of the subfolders, but I don't know how to delete the subfolder(directory) itself. I am new to Java, please help me. Thanks in advance.

Just call directory.delete(); at the end of the method, between lines 13 and 14.
 
Don't get me started about those stupid light bulbs.
