The relativize(Path other) method of java.nio.file.Path used to create a relative path between this path and a given path as a parameter. Relativization is the inverse of resolution. This method creates a relative path that when resolved against this path object, yields a path that helps us to locate the same file as the given path. For example, if this path is “/dir1/dir2” and the given path as a parameter is “/dir1/dir2/dir3/file1” then this method will construct a relative path “dir3/file1”. Where this path and the given path do not have a root component, then a relative path can be constructed. If anyone of the paths has a root component then the relative path cannot be constructed. When both paths have a root component then it is implementation-dependent if a relative path can be constructed. If this path and the given path are equal then an empty path is returned.
Syntax:
Path relativize(Path other)
Parameters: This method accepts a one parameter other which is the path to relativize against this path.
Return value: This method returns the resulting relative path, or an empty path if both paths are equal.
Exception: This method throws IllegalArgumentException if other is not a Path that can be relativized against this path.
Below programs illustrate relativize() method:
Program 1:
Java
// Java program to demonstrate// java.nio.file.Path.relativize() methodimport java.nio.file.Path;import java.nio.file.Paths;public class GFG { public static void main(String[] args) { // create objects of Path Path path = Paths.get("D:\\eclipse\\p2" + "\\org\\eclipse"); Path passedPath = Paths.get("D:\\eclipse\\p2" + "\\org\\eclipse\\equinox\\p2\\core" + "\\cache\\binary"); // print paths System.out.println("This Path:" + path); System.out.println("Given Path:" + passedPath); // call relativize() to create // a relative path Path relativize = path.relativize(passedPath); // print result System.out.println("Relative Path: " + relativize); }} |
Program 2:
Java
// Java program to demonstrate// java.nio.file.Path.relativize() methodimport java.nio.file.Path;import java.nio.file.Paths;public class GFG { public static void main(String[] args) { // create objects of Path Path path = Paths.get("\\nEclipseWork"); Path passedPath = Paths.get("\\nEclipseWork\\GFG" + "\\bin\\defaultpackage"); // print paths System.out.println("This Path:" + path); System.out.println("Given Path:" + passedPath); // call relativize() // to create a relative path Path relativize = path.relativize(passedPath); // print result System.out.println("Relative Path: " + relativize); }} |
