Question#2: Design and implement a Java program using Abstract Factory and Singleton design
patterns.
The
program displays date and time in one of the following two formats:
Format 1:
Date: MM/DD/YYYY
Time: HH:MM:SS
Format 2:
Date: DD-MM-YYYY
Time: SS,MM,HH
The following is how the program works. In the beginning, the program asks the user what
display format that she wants. Then the program continuously asks the user to give one of the
following commands, and performs the corresponding task. Note that the program gets the
current date and time from the system clock (use the appropriate Java date and time operations
for this).
'd' display current date
't': display current time
'q': quit the program.
• In the program, there should be 2 product hierarchies: "DateObject” and “TimeObject”. Each
hierarchy should have format and format2 described above.
•
Implement the factories as singletons.
• Run your code and attach screenshots of the results.
• Draw a UML class diagram for the program.

The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 (attached) illustrates the end-to-end transport of a message with and without message segmentation. Consider a message that is 106 bits long that is to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 5 Mbps. Ignore propagation, queuing, and processing delays. a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host? b. Now…arrow_forwardConsider a packet of length L that begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1, 2, 3. The packet switch delays each packet by dproc. Assuming no queuing delays, in terms of di, si, Ri, (i = 1, 2, 3), and L, what is the total end-to-end delay for the packet? Suppose now the packet is 1,500 bytes, the propagation speed on all three links is 2.5 * 10^8 m/s, the transmission rates of all three links are 2.5 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay?arrow_forward
