Path Join

Path.of joins path segments without hard-coding the platform separator.

PathJoin.java

import java.nio.file.Path;

public class PathJoin {
    public static void main(String[] args) {
        int lesson = ;
        String fileName = "lesson" + lesson + ".txt";
        Path path = Path.of("java", "files", fileName);

        System.out.println("parent=" + path.getParent());
        System.out.println("file=" + path.getFileName());
    }
}

import java.nio.file.Path;

public class PathJoin {
    public static void main(String[] args) {
        int lesson = ;
        String fileName = "lesson" + lesson + ".txt";
        Path path = Path.of("java", "files", fileName);

        System.out.println("parent=" + path.getParent());
        System.out.println("file=" + path.getFileName());
    }
}
