- Requirement: In this assignment, you are going to handle exceptional cases in the bank account class for foreign currencies. In the attached files, source codes for ForeignCurrencyAccount and Account classes are given. There is also Test3.java and Transaction.java that run operations on the bank accounts. Please complete the implementation of ForeignCurrencyAccount and Account classes, so that following exceptional cases are handled by them. Do not add new attributes or methods to ForeignCurrencyAccount and Account classes. Just add code to throw exceptions or handle exceptions. Exceptional cases: 1. Whenever a transaction amount given to "withdraw" method is greater than account's balance, an exception of class InsufficientFundsException should be thrown. 2. Whenever InsufficientFundsException is caught within buyForeignCurrency or sellForeignCurrency methods, an Exception should be thrown with description "Foreign currency buy/sell transaction failed because of insufficient funds".…Allow the user to enter the internet address (URL) and programming language of the web store.In this lab, you create a derived class from a base class, and then use the derived class in a C++ program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Ensure the file named Motorcycle.cpp is open in your editor. Create the Motorcycle class by deriving it from the Vehicle class. Use a public derivation. In the Motorcycle class, create a private attribute named sidecar. The sidecar attribute should be data type bool. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate() method. This method overrides the accelerate() method inherited from the Vehicle class. Change the message in the accelerate() method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named…
- Create a new project named lab7_1. You will be implementing a Tacos class. For the class attributes, let’s use to type of taco, number of tacos, and price. Note that the price per taco of any type is 99 cents. Therefore, allow the taco type and number of tacos to be set directly, but not the price! The price should be set automatically based on the number of tacos entered. So a good idea may be to call the setter for the price inside the function that sets the number of tacos. Some other requirements: A default constructor and a constructor with parameters for your taco type and number of tacos member variables. You should also include setters and getters for these private member variables. However, make sure that the setter for price is private! You don’t want anyone outside the class modifying price. This setter should be called anytime you change the number of tacos. Your constructor needs to call a set method that allows you to set the two member variables, thus takes two…Choose necessary patters, draw the UML and code just company class methods on paper. A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application.This is the information after the two pictures. Also, your class should be placed in a namespace "cs_sequence". Here is an example of a simple client program, to give you an idea about how sequences might be used. You can also use this to test your class, but it's far from exhaustive. Keep in mind as you write your class that you should test each member function after you write it. int main() { Sequence s; for (int i = 0; i < 6; i++) { s.insert(i); } for (s.start(); s.is_item(); s.advance()) { cout << s.current() << " "; } cout << endl; } This client program will print the numbers 5 4 3 2 1 0. (They are backward because insert() inserts each new item at the front of the list.) Implementation We will be using the following implementation of type Sequence, which includes 5 data members. numItems. Stores the number of items in the Sequence. headPtr and tailPtr. The head and tail pointers of the linked list. If the Sequence has no items, then these pointers are…

Inside the main() method of the Watch class, do the following:a) Create a new instance of the “AnalogWatch” class using the overloaded constructorand assign it to the object reference of type “Watch”.b) Create a new instance of the “DigitalWatch” class using the overloaded constructorand assign it to the object reference of type “Watch”.c) Display the content of both the objects.d) Display the current time using the two objects created above respectively Code: public abstract class Watch { //Data Fields private String brand; private String material; private double…Hello, my first time being here I actually stuck on this assignment that was given from last week. I'm currently working on the last piece of this assignment I would greatly appreicate to any solutions.

Create a class named Wedding for a wedding planner that includes the date of the wedding,the names of the Couple being married, and a String for the location.Provide constructors for each class that accept parameters for each field, and provideget methods for each field. Then write a program that creates two Wedding objects and in turn passes each to a method that displays all the details. Save the files as Person.java, Couple.java, Wedding.java, and TestWedding.java. Here's what I have so far: //Person Class import…Java Code.

- I have provided you with 3 interfaces (HasLegs, HasWings, and BreathesUnderwater) and a Tester class. I want you to create 6 new classes: • 2 that implement HasLegs • 2 that implement HasWings • 2 that implement BreathesUnderwater For each of the classes, you will have to implement the methods that the interface dictates. In addition, override toString so that it prints out a simple message describing what the object is. See the example output of my implementation below for an idea how to do that. The Tester class creates 3 ArrayLists, one for each interface. It also loops through each ArrayList and prints out its contents using toString and the interface methods. In between those two chunks of code, you’ll see a //TODO: comment. It is there that I want you to create one object for each of the 6 classes you created and add that object to the appropriate ArrayList. Once you have done all that, you should be able to run your program and see output like the following: I am a table.

Hint: Use the code for how we found all the setosa_locs as an example! Using iris_df, find the location of all the data sample locations for the versicolor class which has a label of 1. To do so, use NumPy's np.where() function. Using iris_df, find the location of all the data sample locations for the virginica class which has a label of 2. To do so, use NumPy's np.where() function. setosa_locs = np.where(iris_df['class'] == 0)[0] # TODO 2.1versicolor_locs = # TODO 2.2virginica_locs = todo_check([ (type(versicolor_locs) is np.ndarray, "'versicolor_locs' is not type np.ndarray.
