1. Write a class named Triangle, containing: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. A method named getArea() that returns the area of this triangle. A method named getPerimeter( that returns the perimeter of this triangle. A method named toString() that returns a string description for the triangle. The formula to compute the area of a triangle is shown below, s = (sidel+side2+ side3) / 2 area = Js(s- sidel)(s- side2)(s– side3) The toString() method is implemented as follows: return "Triangle: sidel sidel + " side2 = " + side2+ " side3 = " + side3; = " Write a test program named TestTriangle that creates a Triangle object with sides 1, 1.5, 1, an displays the area, perimeter, and the description for the triangle.

5. CODE IN PYTHON Create a BankAccount class which has an __init__ method which accepts an account name and starting balance to store as instance fields. The class should also have a method to deposit money, a method to withdraw money, and a method called "get_balance" which returns a string of the format "{account_name} has a balance of {balance}" (do not print this out from within the class, just return the string). In the same file, create an instance of the BankAccount class with a hardcoded name and starting balance. Deposit any amount to the account and withdraw any amount from the account (both can be hardcoded) and then print the result of calling the get_balance method on the instance.

Create a class named CarRental that contains field's for: renter's name, zip code,size of car, daily rental fee, length of rental (in days), and total rental fee. The class should include a constructor that requires all the rental data except the daily rate and total fee, which are calculated based on the size of the car: economy size ($ 29.99 per day), midsize ($ 38.99), and full size ($ 43.50). The class also includes a display() method that will display all the rental information. Create a subclass name LuxuryCarRental. This class sets the rental fee at $79.99 per day and prompts the user to respond to the option of including a chauffeur at an addition $200 per day. Override the parent class display() method to include chauffeur fee information. Write an application named UseCarRental that prompts the user for the data needed for a rental and creates an object of the correct type. Display the total rental fee.
Part A Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent. Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field. Also create a get method for each field. Part B Write an application called TestApartments that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available. An example of the program is shown below: Enter minimum number of bedrooms needed >> 2 Enter minimum number of bathrooms needed >> 1.5 Enter maximum rent willing to pay >> 1200 Apartments meeting criteria of at least 2 bedrooms, at least 1.5 baths, and no more than…
