how to create a Folder inside a folder in java

Question

I have tried to find the path of an existing folder in the same maven project package and create another folder from it.

the existing folder is called client101.userinfo i have tried to do:

File dir = new File("client101.userinfo/userdat");

what am I doing wrong?

Answer 1

You need to use method mkdirs()

new File("/path/directory").mkdirs();

"directory" is the name of the directory you want to create.
