Student will demonstrate the ability to apply the IS A and HAS A relationships. Program Specifications: Start by watching Video Segment 16 from Dr. Colin Archibald's video series (found in the module overview). Key in the program shown in the video and make sure it works. Then, add the following: Animals have a Weight. Animals have a Height. Dog is an Animal. Dogs have a Name. Dogs have a Breed. Dogs have a DOB. Cat is an Animal Cats have a Name. Cats have 9 lives, so you need to keep track of the remaining lives once a cat dies. Bird is an Animal Birds have a wing span Birds have a canFly which is true or false (some birds cannot fly) Create a test class that creates one of each type of animal and displays the animal’s toString method.

You can watch the small video demo on WebOnline to get a better understanding. In additional to what we did in Lab3 you are going to; • Add a control panel. • Add two buttons to the panel called "Smaller" and "Bigger". • Menubar of this program should have an item called "Set Default"which will reset the values of x, y, dx and dy to the values they had initially. • Modify the action listener according to the buttons and menu item. • Set the title to "Mickey" in the constructor and add your WindowListener. • Modify your paint method to draw 3 ovals which makes up Mickey Mouse silhouette. Smaller ovals have half the radius of the big oval. • The center of the circle is determined by the variables x and y, and the radius of circles should be dependent on dx and dy (which are equal since we are using circles). •…arrow_forward

The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso18811973Three Musicians1921 the output is: Artist: Pablo Picasso (1881-1973)Title: Three Musicians, 1921 If the input is: Brice Marden1938-1Distant Muses 2000 the output is: Artist: Brice Marden, born 1938Title: Distant Muses, 2000arrow_forwardC# language Create a Product class then create an object from that class using User Input.

- Number Guessing Program using java: The player has to guess a number given in between a range. If the guessed number is right, the player wins else, loses. It also has the concept of limited attempts where the player has to guess the number within the limited attempts given.

You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object.

Create a class that models a game cell. A game cell should have the following properties: a.Its row and column. These should initially be set to -1. b.Its visited boolean value. This should initially be set to false. c.Live boolean value. This should initially be set to false. "Live" set to true will indicate that the cell is a "live bomb" cell. d.The number of neighbors that are "live." This should initially be set to 0. The Cell class should have a constructor, as well as getters and setters for all properties. 3.Create a class that models a game board. A game board should have the following properties: a.Size. The board will be square, where the size includes the dimensions of both the length and width of the board. b.Grid. The grid will be a 2-dimensional array of the type cell. c.Difficulty.

The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forwardPublic classTestMain { public static void main(String [ ] args) { Car myCar1, myCar2; Electric Car myElec1, myElec2; myCar1 = new Car( ); myCar2 = new Car("Ford", 1200, "Green"); myElec1 = new ElectricCar( ); myElec2 = new ElectricCar(15); } }arrow_forward
