B - RobotFriend
Create a RobotFriend class. RobotFriend is a new toy just on the market. Copy the
starter class and the tester from Codecheck. A RobotFriend has a name and replies to
various commands
Provide a constructor that takes the name of the RobotFriend as a parameter.
Remember that a constructor has the same name as the class.
What does the class need to remember? That is the instance variable.
Provide the following methods:
public String getName () gets the name of this RobotFriend
• public void setName (String newName) sets a new name for this
RobotFriend
• public String whatDoYouNeed () returns a string consisting of name +
needs a battery charge" where name is the name of this RobotFriend
(which was supplied in the constructor)
public String doCommand (String whatToDo) returns a string consisting of
"Your friend "
+ name +
does not
+ whatToDo where name is the name
of this RobotFriend and whatToDo is the parameter

B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…

Please complete the following tasks: Write a class “Actor” that contains two attributes with the appropriate level of visibility explicitly defined. “Name” which is a String, Private, “NumberofAwards” which is an integer, private Write a default Constructor for this class that initializes the name to “Bob Smith” , and the number of awards to 0. Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.
For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…
Part 1: Setting the turtle size when it is instantiated Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following: Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. Add an empty method body. Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE. In the method body of the one-parameter constructor do the following in this order: Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter. Compile the program and fix any…
A Door Class A computer game usually has many different objects that can be seen and manipulated. One typical object is a door. Whether a player runs through a castle, attacks the forces of an evil empire, or places furniture in a room, a door often comes into play. Implement a Door class as described below as well as a TestDoor class that instantiates three Door objects labeled “Enter,” “Exit,” and “Treasure.” The “Enter” door should be left unlocked and opened. The “Exit” door should be left closed and locked. The “Treasure” door should be left open but locked. A Door class A Door object can • display an inscription, • be either open or closed, and • be either locked or unlocked. Here are some rules about how Door’s work. • Once the writing on a Door is set, it cannot be changed. • You may open a Door if and only if it is unlocked and closed. • You may close a Door if and only if it is open. • You may lock a Door if and only if it is unlocked, and unlock a Door if…

Hello! I am having trouble with my intro to JAVA course. I have basic understanding of it, I am failing to get the gets/sets and the DEMONSTRATION part of the assignment. TIA for the help
Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
3- Create a class named Player with a default name as "player", a default level as 0, and a default class type of "fighter". Feel free to add any other attributes you wish! Create an instance method in the Player class called attack that takes another player as a parameter. This function should compare the level of the two players, and return whether the player won, lost, or tied. Finally create a loop that allows the user to input a name and a class type for two players; the level of both players should be determined at random (between 1 and 99). Print out the name and attributes of each player, and have the first player attack the second. Print whether the player won, lost, or tied. Ask if the user wants to try again. (Python code)
