Client Socket Information
In this section, you will learn how to get client
socket information. This is a very simple program of java network. Here, we have
used the class named ClientSocketInformation.java that implement the
constructor of the Socket class passing two arguments as hostName
and TIME_PORT. This program throws an IOException for the exception
handling. This exception is thrown to indicate an I/O problem of some sort
occurred.
Here, we are going to explore a method to retrieve
the host name of the local system in a very simple way. In this way we find out
the Local address, Local host information, reuseAddress, and address of
the local system in a very simple manner.
Code Description
Here we are going to define about all the using
method.
isBound(): This
is a boolean type method. This method returns the binding state of the socket.
isConnected(): This method inform about the socket connectivity
that is connected from server or may not.
getSoTimeout(): This method returns
the setting for So_TIMEOUT 0 returns implies that the option is disabled.
getSoLinger(): This is the method returns setting for SO_LINGER. -1
returns imply that the option is disabled.
