Chapter 1, Problem 21E

Create an object of class Student. You will notice that this time you are prompted not only for a name of the instance, but also for some other parameters. Fill them in before clicking OK. (Remember that parameters of type String must be written within double quotes.)

Add comments as appropriate. Be sure that your program output is neatly presented to the user.  Add documentation comments to your functions. You are going to change the class you created in Program7 so that it has a constructor and some properties. In your GeoPoint class make the following changes (note your variable, parameter and method names may be different. Adjust as needed.): Add a constructor __init__(self, lat=0, lon=0,description = ‘TBD’) that will initialize the class variables __lat ,__lon and the __description. Notice that the constructor will also default lat and lon to zero and description to ‘TBD’ if they are not provided. Change the SetPoint method so that instead of individual coordinates SetPoint(self, lat, lon) it takes a single sequence. Add a property: Point = property(GetPoint,SetPoint). Make sure GetPoint and SetPoint are the names you used for the get and set methods you already wrote for points. Add another property: Description = property(GetDescription,…
In this assignment, you will need to add a new method to the Date class, which you can find on D2L in the "Sample Code" section. The new method should make a Date object's day, month, and year value change to the next day. In other words, add one day to the object's current date. Do not use any part of the built-in DateTime class, but you may want to use the DaysInMonth() method from the Date class. Examples: • If the Date object stores the date 12/31/2021, then after calling your method it should store the date 1/1/2022 • If the Date object stores the date 2/28/2022, then after calling your method it should store the date 3/1/2022 As noted in the common instructions, you only need to turn in your new method, not the entire Date class.
The first version of Abby’s Eggs worked but was a bit cumbersome. I.e. you couldn’t edit a single parameter, you had to always re-enter all of them.  Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class. Have separate methods for updating the parameters. Use a switch statement to take menu selections for updating parameters or outputting results. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated. Before displaying updated menu, “clear the screen” I got most of the code working, but I can't find a way to clear the sceen before displaying the updated menu. I tried using "System.out.print("\033[H\033[2J"); System.out.flush();", but it is not working. I am using the Apache NetBeans IDE.
