Programming Assignment 3: UDP Pinger Lab In this lab, you will study a simple Internet ping server written in the Java language, and implement a corresponding client. The functionality provided by these programs are similar to the standard ping programs available in modern operating systems, except that they use UDP rather than Internet Control Message Protocol (ICMP) to communicate with each other. (Java does not provide a straightforward means to interact with ICMP.)
The ping protocol allows a client machine to send a packet of data to a remote machine, and have the remote machine return the data back to the client unchanged (an action referred to as echoing). Among other uses, the ping protocol allows hosts to determine round-trip times to other machines.
You are given the complete code for the Ping server below. Your job is to write the Ping client.
Server Code
The following code fully implements a ping server. You need to compile and run this code. You should study this code carefully, as it will help you write your Ping client.
