Java I/O How to - Compare two path with compareTo








Question

We would like to know how to compare two path with compareTo.

Answer

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
// w w w  .  j  a va2 s.c  o m
public class Main {
  public static void main(String[] args) {
    Path path1 = Paths.get("/home/docs/users.txt");
    Path path2 = Paths.get("/home/docs/users.txt");
    Path path3 = Paths.get("/home/music/A.mp3");

    testCompareTo(path1, path2);
    testCompareTo(path1, path3);

  }

  private static void testCompareTo(Path path1, Path path2) {
    if (path1.compareTo(path2) == 0) {
      System.out.println("identical");
    } else {
      System.out.println("NOT identical");
    }
  }
}

The code above generates the following result.
