How can the program in problem be modified to output the subtotal after each value is added instead of just the final result? Include messages in the OUTPUT statements to distinguish between the subtotal and the grand total. Check the program to insure that it works correctly.
Two changes (shown in bold below) are needed:
• Add a subtotal OUTPUT statement immediately below the accumulation statement
• Modify the final OUTPUT statement to include a "grand total" message.

Based on Example1Receiver.java, create a program Example1aReceiver.java which joins a multicast group of a different IP address (e.g., 239.1.2.4) but the same port. Compile Example1bReceiver.java. Start two or more Example1Receiver processes first, then a Example1a Receiver process, and then a Sender process with a message of your choice. Does the Example1bReceiver process receive the message? Describe and explain the outcome.
This exercise is based on Example1 presented in this chapter.
