Chapter 3, Problem 27E
Open the clock-display project and create a ClockDisplay object by selecting the following constructor:
new ClockDisplay( )
Call Its getTime method to find out the initial time the clock has been set to. Can you work out why it starts at that particular time?

Students have asked these similar questions
Create another ticket machine for tickets of a different price; remember that you have to supply this value when you create the machine object. Buy a ticket from that machine. Does the printed ticket look any different from those printed by the first machine?
Write the code for the timeTick method in ClockDisplay that displays hours, minutes, and seconds, or even implement the whole class if you wish.
Please help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game.
INFORMATION:
The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room.
The Cave
The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how room 1…

- Can you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.arrow_forwardIn class BouncingBall, you will find a definition of gravity (a simple integer). Increase or decrease the gravity value; compile and run the bouncing ball demo again. Do you observe a change?arrow_forward2. Write an interface for Tossable. We will say that every Tossable item has a way to toss it and we want to be able to give its color. A Tossable item by default is to throw an assist toss to another player.arrow_forward

Write a Java program “PointTester”, that constructs two points with coordinates (3, 4) and (–3, –4). Find the distance between them, using the distance method.

- Currently, there are two draw rectangle methods in the DoodleController class. Since two different turtles need to draw a rectangle, create a draw rectangle method in the DoodleTurtle class that will take the width and height of the rectangle as parameters and draw a rectangle of the specified size. The size will be the number of steps by the turtle. With the new method introduced, the calls to drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle can be replaced with a call to the turtle’s drawRectangle method passing in the desired size of the rectangle. Refactor the DoodleController accordingly. Note: When you are done with the refactoring the drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle method in the DoodleController need to be deleted. After this refactoring, do not move on until you verify the program works as it did before.arrow_forwardCreate a VisualCounter class that supports both increment and decrement operations. Take the constructor inputs N and max, where N indicates the maximum number of operations and max specifies the maximum absolute value for the counter. Create a plot that shows the value of the counter each time its tally changes as a side effect.arrow_forwardThis is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Classarrow_forward
- Create a new project for this program called TestOldMaid and add a class with a main() method. In the project: Copy your Deck and Card class from the earlier project into it. Create a subclass of Deck called OldMaidDeck. It is special because one of the Queens is missing so it only has 51 cards. Create a constructor method that calls the super class constructor, then removes a queen. Override the toString method so it returns the name of the deck and the number of cards in it. Write the test main() method. Create an OldMaidDeck object and deal all the cards to six players. It is ok if not everyone has an equal number of cards. Use arrays or ArrayLists for the players hands. Show the hands of all 6 players. Refer to the web to find out more about the Old Maid card game: https://bicyclecards.com/how-to-play/old-maid/ Fully document all classes with your name, date and description. And each data member and method is documented. Each block that does something is also documented.arrow_forwardCreate a new project for this program called TestOldMaid and add a class with a main() method.
