Java file path util
Defines channels, which represent connections to entities that are capable of performing I/O operations, such as files and sockets; defines selectors, for multiplexed, non-blocking I/O operations.
Defines interfaces and classes for the Java virtual machine to access files, file attributes, and file systems.
Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).

Java file path util
Path testFile = Paths.get(«C:\\Users\\jleom\\Desktop\\java\\javarush task\\test.txt»); Path testFile2 = Paths.get(«C:\\Users\\jleom\\Desktop»); System.out.println(testFile.relativize(testFile2));
Класс Path и класс Paths предназначены для работы с файловой системой в Java, однако они предоставляют разные функции и методы. Path — это интерфейс, который определяет методы для работы с путями к файлам и каталогам в файловой системе. Он предоставляет ряд методов для работы с путями, таких как resolve(), relativize(), getParent(), getFileName(), toAbsolutePath() и другие. Paths — это утилитный класс, который предоставляет статические методы для создания экземпляров класса Path. Он не имеет методов для работы с путями напрямую, но предоставляет методы для создания экземпляров Path из строковых значений или URI. Еще методы по классу Paths: getFileSystem(): возвращает объект FileSystem, представляющий файловую систему, которой принадлежит данный путь. getDefault(): возвращает объект FileSystem, представляющий файловую систему по умолчанию. getTempDirectory(): возвращает объект типа Path, представляющий временный каталог. getHomeDirectory(): возвращает объект типа Path, представляющий домашний каталог пользователя. exists(Path path, LinkOption. options): проверяет, существует ли файл или каталог, представленный указанным путем. Класс Paths удобен для работы с файловой системой, так как он предоставляет простой и удобный API для работы с путями.
Надо добавить в статью, Paths.get был в 8 Java. Потом появился Path.of. Если у вас не работает Path.of (версия Java не позволяет), только тогда нужен Paths.get
