Paths

All files and folders on your computer can be located by a "path" like "Downloads/movie.mp4."

To store a path in a Java program we use the Path class from the java.nio.file1 package. You create these Paths by giving a String to the Path.of static method.

import java.nio.file.Path;

class Main {
    void main() {
        Path pathToNotes = Path.of("notes.txt");

        IO.println(pathToNotes);
    }
}

nio stands for "new IO." So yes, there was an old IO. We will use that too. Its one of many artifacts from Java's interesting and sordid history.
