How to ping an IP using a socket and send data through it?

Question

How can I ping an IP address using a socket program and send data through it?

Answer 1

You can't do ping in Java -- ping works at ICMP level which works on top of IP, whereas Java offers support for UDP (which sits on top of IP) and TCP (again on top of IP). It's basically a different (higher level) protocol for which you will need your own (native) library written in order to gain access to the IP stack.
