Creates a stream socket and connects it to the specified port number on the named host.
If the specified host is null it is the equivalent of
specifying the address as InetAddress.getByName(null).
In other words, it is equivalent to specifying an address of the
loopback interface.
If the stream argument is true, this creates a
stream socket. If the stream argument is false, it
creates a datagram socket.
If the application has specified a server socket factory, that
factory's createSocketImpl method is called to create
the actual socket implementation. Otherwise a "plain" socket is created.
If there is a security manager, its
checkConnect method is called
with the host address and port
as its arguments. This could result in a SecurityException.
If a UDP socket is used, TCP/IP related socket options will not apply.
host | the host name, or null for the loopback address. | |
port | the port number. | |
stream | a boolean indicating whether this is
a stream socket or a datagram socket. |
IOException | if an I/O error occurs when creating the socket. | |
SecurityException | if a security manager exists and its
checkConnect method doesn't allow the operation. | |
IllegalArgumentException | if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive. |
