Scala: Create File with a Folder Using Relative Path (Not Absolute Path)

Question

In my Scala code I want to create a folder "c:/temp" and then create a file "file.txt" within that folder. I don't want to have to use "c:/temp/file.txt". So, I want to use the relative path of the file to create it within that folder.

Imagine how a human creates a folder and then a file? He creates a folder; goes in the folder, and then creates the file inside that folder. That's what I want to do.

=====

Added the following to make this more clear: Let's say I created the folder and I have a File object called myFolder that represents that folder. What I want is to be able to do something like myFolder.createFile("file.txt").

Files.createDirectory(Paths.get("/temp")) provided that you have root priviledges. — jrook

Sorry, I didn't explain clearly. I don't care about the root part; I don't worry about the permission. I changed the question to make it more clear. — user1888243

It is not more clear ;) You can use the Java instruction in my previous comment to create a directory from a string. After folder creation. You can use the path temp to write files inside the newly created directory. — jrook

val subFile = new File(myFolder, "file.txt")

From the description of the File(File parent, String child) constructor found at the docs page:

Creates a new File instance from a parent abstract pathname and a child pathname string.

The OP is asking if they can do: myFolder.createFile("file.txt") with myFolder being some object representing the destination folder.
