- # 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…If we do not override the toString method in a class, the toString method for the Object is called. The default output is <class name>@<memory location>. True FalseTrue or False: "this" is a reference to the current object in an instance method or function Object() { [native code] }.
- 2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.Book Donation App Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes: 1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties. • donorID references the book’s donor. This…17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.
- Computer Engineering lab Assignment 3:- Apex (Salesforce) - Create an apex class - In the apex class we have to create 1 method. - Method return type is void & the argument is null. - Method : - Map<String,String> static 4 values---- Put the value at the time of initialization---- Put the value using the map method PUT.True/ False 1- Class objects can be defined prior to the class declaration. 2- You must use the private access specification for all data members of a class. 3- If an array is partially initialized, the uninitialized elements will be set to zero. 4- A vector object automatically expands in size to accommodate the items stored in it. 5- With pointer variables, you can access but not modify data in other variables. 6- Assuming myValues is an array of int values and index is an int variable, both of the following statements do the same thing. 1. cout header file. 15- To solve a problem recursively, you must identify at least one case in which the problem can be solved without recursion.11:02 all 10% + Create 1 1000.01 Create 2 2000.02 Create 3 3000.03 Deposit 111.11 Deposit 2 22.22 Withdraw 4 5000.00 Create 4 4000.04 Withdraw 1 0.10 Balance 2 Withdraw 2 0.20 Deposit 3 33.33 Withdraw 4 0.40 Bad Command 65 Balance 1 Balance 2 Balance 3 Balance 4
- Data structure & Algorithum java program Write a class name month. The class should have an int field named monthNumber that holds the number of the month. For example, January would be 1, February would be 2, etc. The class should also have appropriate constructors and getter / setter methods. There should also be a getMonthName that returns the name of the month corressponding to the month number. Also include exception code when a number less than 1 or greater than 12 is given in the constructor and/ or the set method. Demonstrate the classess and catching the exception in a program, such as Month Test. Display appropriate information to the user if an erro occurs.1. // MAINTENANCE10 // This program accepts data about 100 books and // determines a price for each. // The price is 10 cents per page for the // first 200 pages, then 8 cents // per page after that. // After pricing, all the data is displayed. // Create a Book class and modify the program to use // an array of Book objects instead of individual // data items. start Declarations num SIZE = 100 num sub string titles[SIZE] num pages[SIZE] num prices[SIZE] num MIN_PAGES = 200 num HIGH_PRICE = 0.10 num LOW_PRICE = 0.08 sub = 0 while sub < SIZE output "Enter title … " input title[sub] output "Enter pages … " input pages[sub] if pages[sub]IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
