Step by step
Solved in 2 steps with 1 images
- TRUE OR FALSE A method that uses a generic class parameter can be static or dynamic.Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.in C# Create a Bank class with the following properties: List of bank accounts (List<BankAccount>) Create the following methods in the Bank class: AddAccount(BankAccount account): Method to add a new bank account to the list of accounts RemoveAccount(string accountNumber): Method to remove an existing bank account from the list of accounts SearchAccount(string accountNumber): Method to search for an existing bank account and return the account details my code is // This class represents a bank, which has a list of BankAccount objects as one of its properties. public class Bank { // This property holds a list of BankAccount objects belonging to the bank. public List<BankAccount> Accounts { get; set; } // This constructor initializes the list of accounts for the bank. public Bank() { Accounts = new List<BankAccount>(); } // This method adds a new BankAccount object to the bank's list of accounts. public void…
- Problem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…DiceSet Write a class named DiceSet that contains a list of Die objects. Fields dice a list of Die objects Methods __init__(self, dice_faces) The constructor should instantiate the dice list to an empty list if no parameters are set. The constructor should take a list of integers. Add one die to the dice set for each integer with the number of faces equal to the integer. pop_die(self, value) Remove and return the first die with the given value from the list. add_die(self, die) Adds the given die (of class Die) to the dice list. roll(self) Roll all the die objects in the list of dice and return their sum. die_values(self) Return a list of the int values (last rolls) of the dice in the list. __str__(self) returns a string version of a dice set. Example: "{[d3] 1, [d6] 4, [d12] 5, [d4] 3}"Scores Class Write a class named Scores which should have the following attribute: • _scores (a list to hold test scores, 0 - 100. Initially empty. ) The Scores class should have an _init__ method that creates the _scores attribute. It should also have the following methods: • add_score: this method adds a score to the __scores list. It accepts a single score as it's' only argument. • get_average: this method accepts no arguments. If _scores is empty, this method returns -1. Otherwise, it returns the average of all scores in _scores. • get_high_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the highest score in __scores. • get_low_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the lowest score in scores. • _str_: This method returns a string similar to the following (assuming the _scores contains 89, 77, 93): Once you have written the class, write a program that…

Write a short code snippet illustrating each situation. Explain the problem if this class did not provide a deep copy constructor function. // POST: empty object with room for 10 titles // POST: object is destructed // pointer to dynamic array of book titles // capacity of array // number of books used in the bookstore
