The normalize() method from Path interface returns a Path after removing dot, double dots.
This method does not access the file system.
A normalized path may not locate the same file as the path contained a symbolic link.
The following code shows some examples of normalizing paths on Windows.
import java.nio.file.Path; import java.nio.file.Paths; public class Main { public static void main(String[] args) { Path p1 = Paths.get("C:\\myData\\..\\\\myData\\Main.java"); Path p1n = p1.normalize();/*from www. ja v a 2s . co m*/ System.out.println(p1 + " normalized to " + p1n); Path p2 = Paths.get("C:\\myData\\Main.java"); Path p2n = p2.normalize(); System.out.println(p2 + " normalized to " + p2n); Path p3 = Paths.get("a\\..\\.\\test.txt"); Path p3n = p3.normalize(); System.out.println(p3 + " normalized to " + p3n); } }
