- · Exercise # 2: Implement a class Portfolio. This class has two objects, checking and saving, of the type bankAccount that was developed in the worked example. Initialize the 2 bank accounts with 0 initial balance. . Implement four methods • def deposit (self, amount, account) • def withdraw (self, amount, account) • def transfer (self, amount, account) • def getBalance (self, account) • Here the account string is "S" or "c" for Saving and Checking, respectively. For the deposit or withdraw, it indicates which account is affected. For a transfer, it indicates the account from which the money is taken; the money is automatically transferred to the other account. • To test your class: . create one Potfolio object • deposit 10000 in its checking account . transfer 5000 from checking account to saving account . withdraw 2500 from checking account display the balance of both accounts • A run for the above test program will result in the following output 5000.0 Saving balance = Checking…Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class.

- Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…Task 1: Extend the “Circle” class to have the following features. Two additional data members (integers) to store the x and y coordinate of the center of the Circle. A parameterized constructor. Set() and Get() methods for each of the data members. A function to display the data members of the class. A function enlargeCirlce(int); which increases the radius of the circle by the factor passed as input to the For example, if “c” is an object of class Circle, the statement c.enlargeCircle(2); should double the radius of the circle. A function moveHorizontal(int); which should move the center of the circle in the horizontal direction. For example, if “c” is a circle with center at (5,10), moveHorizontal(3); should move the center to position (8,10). A fuction moveVertical(int); similar to the moveHorizontal(int); function. In the main program, create two objects of class Circle. Find which of the two circles is smaller (by comparing their radii) and enlarge the smaller circle by a factor…The Rectangle class) Following the example of the Circle class in Section 9.2, design a class named Rectangle to represent a rectangle. The class contains: ■ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ■ A no-arg constructor that creates a default rectangle. ■ A constructor that creates a rectangle with the specified width and height. ■ A method named getArea() that returns the area of this rectangle. ■ A method named getPerimeter() that returns the perimeter.Draw the UML diagram for the class and then implement the class. Write a test program that creates two Rectangle objects—one with width 4 and height 40and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.
- # Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers for monthly rainfall figures.Create a class namely circle and do the following: (i) Circle will have the following member variables: Point - an inner class having two members variables x and y representing the center and radius (a floating-point number) (ii) Crcate a method in the inner class namely getPoint() to print the point (x, y) that represents the circle center. (iii) Write a main method to create 10 random circles with the grid of (10, 10) and (70, 70).
- Create a class IntArray. Create two constructors. Nullary constructor create an array of size 10 and initiazes all values to 0. Parametrized constructor has signature IntArray(int num, int s). Thiscreates an array of size s and initializes all values. c++16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)#this is a python program #topic: OOP Design a class Joker with parameterized constructor so that the following line of code prints the result shown in the output box.
