Server Sockets
In common language we can say that the sockets are just like
an end-point of two-way communication link over the network between two
programs. Socket classes are used to establish a connection between client
program and a server program. In java there is a java.net package, which
provides two types of classes- first is ordinary socket, which implement
the client side connection and second is server socket, which implement
the server side connection.
In
Java there are many socket class that is used for creating a Server
applications. ServerSockets are quite different from normal Sockets. The main
work of ServerSocket class is to wait for a request of connection by the client
and connect them on published ports and then possibly returns a result to the
requester. The SocketImpl is a common superclass of all classes that actually
implement sockets. It is used to create both client and server sockets.
There
are some constructors that might throw an IOException
under
adverse conditions. Some of the constructors are as under:
| ServerSocket(int
port) |
Creates
server socket on the specified port with a queue
length of 50. |
|
ServerSocket(int
port,
int maxQueue) |
Creates
a server socket on the specified port with a maximum
queue length of maxQueue. |
|
ServerSocket(int
port,
int maxQueue,
InetAddress localAddress) |
Creates
a server socket on the specified port with a maximum
queue length of maxQueue. On
a multihomed host, localAddress
specifies the IP address
to which this socket binds. |
