I need help with Part 2 coded in Java. Thank you.

Part 1:

Starting with the solution to Assignment 2, re-factor the program to do the following:

1. Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class.
2. Have separate methods for updating the parameters.
3. Use a switch statement to take menu selections for updating parameters or outputting results.
4. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated.
5. Before displaying updated menu, clear the screen

Part 2:

Using UMLet or Draw.IO, draw an Activity Diagram of the while loop.
