Java 7 introduced java.nio.file.Path as a possible replacement for java.io.File.
With File, when I access a file under a specific, I would do:
File parent = new File("c:\\tmp");
File child = new File(parent, "child"); // this accesses c:\tmp\child
What's the way to do this with Path?
I supposed this will work:
Path parent = Paths.get("c:\\tmp");
Path child = Paths.get(parent.toString(), "child");
But calling parent.toString() seems ugly. Is there a better way?

Advertisements. As name suggests Path is the particular location of an entity such as file or a directory in a file system so that one can search and access it at that particular location.
In Java, for NIO Path, we can use path. toAbsolutePath() to get the file path; For legacy IO File, we can use file. getAbsolutePath() to get the file path.
Advertisements. Java NIO package provide one more utility API named as Files which is basically used for manipulating files and directories using its static methods which mostly works on Path object.
Use the resolve method on Path.
There are two methods with this name. One takes a relative Path and the other a String. It uses the Path on which it is called as a parent and appends the String or relative Path appropriately.
Path parent = Paths.get("c:\\tmp");
Path child = parent.resolve("child");
