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.arrow_forwardWrite out what you think the outer wrappers of the Student and LabClass classes might look like; do not worry about the inner part.arrow_forward
- .If the name of getBalance is changed to getAmount, does the return statement in the body of the method also need to be changed for the code to compile? Try it out within BlueJ.

No need to run the code.arrow_forwardMust be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…arrow_forward
