Modify Example2SenderReceiver.java so that each process sends out its message 10 times. Compile and run. Describe the run outcomes and hand in the program listings.
This exercise is based on Example2 presented in this chapter.
```
>java Example2SenderReceiver 239.1.2.3 1234 msg1
Hit return when ready to send:
Joined group /239.1.2.3 port 1234

```
Each message receives 30 messages, 10 each from each other.
The code:
```
System.out.println("Sending to " + args[0] +
" port " + port + " 10 times");
for (int i=0; i<10; i++)
socket.send(packet);
socket.close();
```
