In certain computer networks, a message is not sent as a continuous stream of data. Instead, it is divided into pieces, called packets, and sent a packet at a time. The packets might not arrive at their destination in the same order as the one in which they were sent. To enable the receiver to assemble the packets in their correct order, each packet contains a sequence number.
For example, to send the message “Meet me at 6 o’clock” three characters at a time, the packets would appear as follows:
1 | Mee |
2 | t m |
3 | e a |
4 | t 6 |
5 | o' |
6 | clo |
7 | ck |
Regardless of when the packets arrive, the receiver can order the packets by their sequence numbers to determine the message.
Given a text file containing the packets of data in the order they were received, write an application that reads the file and extracts the message by using a sorted list. Design and create auxiliary classes such as Packet and Message.
