    equals() – Compares two abstract pathnames lexicographically.

    The following prints make it clear, that this have not the same path.

    System.out.println(new File("c:\\a").getAbsolutePath());
System.out.println(new File("c:\\a\\").getAbsolutePath());
System.out.println(new File("c:\\a","").getAbsolutePath());
System.out.println(new File("c:\\a\\","").getAbsolutePath());
System.out.println(new File("c:\\a","\\").getAbsolutePath());
System.out.println(new File("c:\\a","\\b").getAbsolutePath());
System.out.println(new File("c:\\a","b").getAbsolutePath());

    output 

    c:\a
c:\a
c:\a
c:\a
c:\a\
c:\a\b
c:\a\b
