Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Path p1 = Paths.get("C:\\Java_Dev\\test1.txt");
    Path p2 = Paths.get("C:\\Java_Dev\\Test1.txt");

    int v1 = p1.compareTo(p2);
    System.out.println(v1);/*from   ww w.ja va2 s .  co  m*/
    int v2 = p1.compareTo(p3);
    System.out.println(v2);
}

From source file:Main.java

public static void main(String[] args) {

    Path path01 = Paths.get("/tutorial/Java/JavaFX/Topic.txt");

    //compare using Path.compareTo
    int compare = path01.compareTo(path02);
    System.out.println(compare);//from  w  w w.  j  a  va 2s  .c o  m
}

From source file:Main.java
