Lesson 15 - Working with files and folders in Java - New API
In the previous lesson, Working with files and folders in Java, we went over the older File
class. In the end of the article, we showed the issues the class suffers from.
Since Java version 7, developers have come up with a new API. This API includes
new classes: Files, Paths and the most important
Path interface. In today's lesson we're going to describe all these
classes.
The Path Interface
The Path interface simply represents a path in a filesystem.
It's good to say that the implementation of this interface depends on the
operating system. As in the lesson on File, we'll
introduce the methods associated with this interface.
Creating an Instance
Since Path is an interface, we have to instantiate it by a
factory method. There are several ways, but two are the most important:
Paths.get(String path): Path- an older way to create an instance; since Java version 11, it only delegates to the next methodPath.of(String path): Path- since Java version 11; creates a new instance based on a path specified in the parameter
Let's show a sample usage:
