In this section, we are
going to explain the method to find out the hostname port number of a local
machine. This program defines the IOException for the exception handling. This
exception is thrown to indicate an I/O problem in the program. Here, we are
giving a complete example named EchoClientSocket.java, in which we call a
Socket class of java.net package, which represented the Hostname.
Its constructor passes two arguments like local machine hostname and port
number. If the machine supports both arguments then Client socket information
will be displayed on command line such as local port number and hostname.
If the local machine doesn't supports the hostname and port number then the
program will give an UnKnownHostException massage.
Here is the code of this program:
Here Output of this program:
I understand about the host: roseindi.
Local port is = 1368
