      @Deprecated public static boolean equals​(java.util.Vector<?> v1, java.util.Vector<?> v2)
      Deprecated.
      since 1.6.x.
      Please use Vector.equals() or List.equals().
      Parameters:
      v1 - the first vector.
      v2 - the second vector.
      Returns:
      true if the vectors are equal.

      @Deprecated public static boolean equals​(java.util.Dictionary<?,​?> d1, java.util.Dictionary<?,​?> d2)
      Deprecated.
      since 1.6.x.
      Dictionary does not have an equals. Please use Map.equals().

      Follows the equals contract of Java 2's Map.

      Parameters:
      d1 - the first directory.
      d2 - the second directory.
      Returns:
      true if the directories are equal.
      Since:

    • flattenToString

      @Deprecated public static java.lang.String flattenToString​(java.util.Collection<?> c)
      Deprecated.
      use stream().collect(Collectors.joining(","))
      Creates a comma separated list of all values held in the given collection.
      Parameters:
      c - collection to transform
      Returns:
      string representation of the collection

      Type Parameters:
      K - type of the key
      V - type of the value
      Parameters:
      m1 - the to directory.
      m2 - the from directory.
