The __str__ method of the Bank class (in bank.py) returns a string containing the accounts in random order. Design and implement a change that causes the accounts to be placed in the string in ascending order of name. Implement the __str__ method of the bank class so that it sorts the account values before printing them to the console. In order to sort the account values you will need to define the __eq__ and __lt__ methods in the SavingsAccount class (in savingsaccount.py). The __eq__ method should return True if the account names are equal during a comparison, False otherwise. The __lt__ method should return True if the name of one account is less than the name of another, False otherwise. The program should output in the following format: Test for createBank: Name: Jack PIN: 1001 Balance: 653.0 Name: Mark PIN: 1000 Balance: 377.0 ... ... ...

CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.

Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
