  Constructor and Description
  InetSocketAddress()
  InetSocketAddress(InetAddress address, int port) Creates a socket endpoint with the given port number port and address.
  InetSocketAddress(int port) Creates a socket endpoint with the given port number port and no specified address.
  InetSocketAddress(String host, int port) Creates a socket endpoint with the given port number port and the hostname host.

  Methods

  Modifier and Type	Method and Description
  static InetSocketAddress	createUnresolved(String host, int port) Creates an InetSocketAddress without trying to resolve the hostname into an InetAddress.
  boolean	equals(Object socketAddr) Compares two socket endpoints and returns true if they are equal.
  InetAddress	getAddress() Gets the address of this socket.
  String	getHostName() Returns the hostname, doing a reverse lookup on the InetAddress if no hostname string was provided at construction time.
  String	getHostString() Returns the hostname if known, or the result of InetAddress.getHostAddress.
  int	getPort() Gets the port number of this socket.
  int	hashCode() Returns an integer hash code for this object.
  boolean	isUnresolved() Returns whether this socket address is unresolved or not.
  String	toString() Returns a string containing the address (or the hostname for an unresolved InetSocketAddress) and port number.

• Constructor Detail

  • InetSocketAddress

    public InetSocketAddress()

  • InetSocketAddress

    public InetSocketAddress(int port)

    Creates a socket endpoint with the given port number port and no specified address. The range for valid port numbers is between 0 and 65535 inclusive.

    Parameters:

    port - the specified port number to which this socket is bound.

  • InetSocketAddress

    public InetSocketAddress(InetAddress address,
                     int port)

    Creates a socket endpoint with the given port number port and address. The range for valid port numbers is between 0 and 65535 inclusive. If address is null this socket is bound to the IPv4 wildcard address.

    Parameters:

    port - the specified port number to which this socket is bound.

    address - the specified address to which this socket is bound.

  • InetSocketAddress

    public InetSocketAddress(String host,
                     int port)

    Creates a socket endpoint with the given port number port and the hostname host. The hostname is tried to be resolved and cannot be null. The range for valid port numbers is between 0 and 65535 inclusive.

    Parameters:

    port - the specified port number to which this socket is bound.

    host - the specified hostname to which this socket is bound.

• Method Detail

  • createUnresolved

    public static InetSocketAddress createUnresolved(String host,
                                     int port)

    Creates an InetSocketAddress without trying to resolve the hostname into an InetAddress. The address field is marked as unresolved.

    Parameters:

    host - the specified hostname to which this socket is bound.

    port - the specified port number to which this socket is bound.

    Returns:

    the created InetSocketAddress instance.

    Throws:

    IllegalArgumentException - if the hostname host is null or the port is not in the range between 0 and 65535.

  • getPort

    public final int getPort()

    Gets the port number of this socket.

    Returns:

    the socket endpoint port number.

  • getAddress

    public final InetAddress getAddress()

    Gets the address of this socket.

    Returns:

    the socket endpoint address.

  • getHostName

    public final String getHostName()

    Returns the hostname, doing a reverse lookup on the InetAddress if no hostname string was provided at construction time.

  • getHostString

    public final String getHostString()

    Returns the hostname if known, or the result of InetAddress.getHostAddress. Unlike getHostName(), this method will never cause a DNS lookup.

    Since:

    1.7

  • isUnresolved

    public final boolean isUnresolved()

    Returns whether this socket address is unresolved or not.

    Returns:

    true if this socket address is unresolved, false otherwise.

  • toString

    public String toString()

    Returns a string containing the address (or the hostname for an unresolved InetSocketAddress) and port number. For example: "www.google.com/74.125.224.115:80" or "/127.0.0.1:80".

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.

  • equals

    public final boolean equals(Object socketAddr)

    Compares two socket endpoints and returns true if they are equal. Two socket endpoints are equal if the IP address or the hostname of both are equal and they are bound to the same port.

    Overrides:

    equals in class Object

    Parameters:

    socketAddr - the object to be tested for equality.

    Returns:

    true if this socket and the given socket object socketAddr are equal, false otherwise.

    Object.hashCode()

  • hashCode

    public final int hashCode()

    Description copied from class: Object
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

    Note that hash values must not change over time unless information used in equals comparisons also changes.

    See Writing a correct hashCode method if you intend implementing your own hashCode method.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.
