Class Overview

This class represents a socket endpoint described by a IP address and a port number. It is a concrete implementation of SocketAddress for IP.

Summary

Public Constructors
InetSocketAddress(int port)
Creates a socket endpoint with the given port number port and the wildcard address InetAddress.ANY.
InetSocketAddress(InetAddress address, int port)
Creates a socket endpoint with the given port number port and address.
InetSocketAddress(String host, int port)
Creates a socket endpoint with the given port number port and the hostname host.
Public Methods
static InetSocketAddress createUnresolved(String host, int port)
Creates an InetSocketAddress without trying to resolve the hostname into an InetAddress.
final boolean equals(Object socketAddr)
Compares two socket endpoints and returns true if they are equal.
final InetAddress getAddress()
Gets the address of this socket.
final String getHostName()
Gets the hostname of this socket.
final int getPort()

Public Constructors

public InetSocketAddress (int port)

Creates a socket endpoint with the given port number port and the wildcard address InetAddress.ANY. The range for valid port numbers is between 0 and 65535 inclusive.

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

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 wildcard address InetAddress.ANY.

Parameters
address the specified address to which this socket is bound.
port the specified port number to which this socket is bound.

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
host the specified hostname to which this socket is bound.
port the specified port number to which this socket is bound.
Throws
SecurityException if a SecurityManager is installed and its checkConnect() method does not allow the resolving of the host name.

Public Methods

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.

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.

Parameters
socketAddr the object to be tested for equality.
Returns
  • true if this socket and the given socket object socketAddr are equal, false otherwise.

public final InetAddress getAddress ()

Gets the address of this socket.

Returns
  • the socket endpoint address.

public final String getHostName ()

Gets the hostname of this socket.

Returns
  • the socket endpoint hostname.

public final int getPort ()

Gets the port number of this socket.

Returns
  • the socket endpoint port number.

public final int hashCode ()

Gets the hashcode of this socket.

Returns
  • the appropriate hashcode.

public final boolean isUnresolved ()

Returns whether this socket address is unresolved or not.

Returns
  • true if this socket address is unresolved, false otherwise.

public String toString ()

Gets a string representation of this socket included the address and the port number.

Returns
  • the address and port number as a textual representation.
