2A. Create a Date class with three integer instance variables named day, month, year. It has a constructor with three parameters for initializing the instance variables, and it has one method named daysSinceJan1(). It computes and returns the number of days since January1ofthe same year, including January 1 and the day in the Date object. For example, if day is a Date object with day = 1, month = 3, and year = 2000, then the call date.daysSinceJan1( ) should return 61 since there are 61 days between the dates of January 1, 2000, and March 1, 2000, including January1 and March 1. Include a DateDemo class that tests the Date class. Don't forget leap years. %3D %3D

In Python 3, write a program with classes to keep track of phones. Here are the requirements: Create a new class called Phone. The Phone class should have a class attribute for the owner's name. Since all phones have a manufacturer and a model number, your class should take the manufacturer and model number from the constructor and assign them to instance attributes. Your Phone constructor should be able to take the parameters. Override the print method for Phone to output a human-friendly version of the information. Your code should prompt the user for an owner name and then start prompting for the manufacturers and models for all phones for that user until the user enters a 'q' or 'Q'. After the entry print out a list of all the phones.
