## Class URLName

- java.lang.Object
- - javax.mail.URLName

-     public class URLName
      extends Object

  The name of a URL. This class represents a URL name and also provides the basic parsing functionality to parse most internet standard URL schemes.

        `MalformedURLException`

    - #### equals

          public boolean equals(Object obj)

      Compares two URLNames. The result is true if and only if the argument is not null and is a URLName object that represents the same URLName as this object. Two URLName objects are equal if they have the same protocol and the same host, the same port number on the host, the same username, and the same file on the host. The fields (host, username, file) are also considered the same if they are both null.

      Hosts are considered equal if the names are equal (case independent) or if host name lookups for them both succeed and they both reference the same IP address.

      Note that URLName has no knowledge of default port numbers for particular protocols, so "imap://host" and "imap://host:143" would not compare as equal.

      Note also that the password field is not included in the comparison, nor is any reference field appended to the filename.

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Compute the hash code for this URLName.
      Overrides:
        `hashCode` in class `Object`
