A TV Class
The attributes of a TV object are the channel, the volume, and a flag (or switch) indicating
whether the TV is on or off. The methods perform the following actions:
• Turn the TV on or off.
• Set the channel to an integer from 0 to 99 inclusive.
• Raise or lower the volume by one unit. The volume can range from 0 to 20.
• View the value of the volume.
• View the channel.
• Determine whether the TV is on or off.
Write a TV class that implements all relevant functions. A newly created TV object is set
to off with the channel set to 2 and the volume initially 10. Include a main(...) method that tests
the methods of the TV class.
Othello is played with white and black pieces. When surrounded by opponents on all sides or top and bottom, a piece is caught and its colour is flipped. You must capture one opponent piece on your turn. When neither player can move, the game finishes. Most pieces wins. Othello object-oriented design.
Step 2: Identify three different classes that might contain each of these objects:
myBlueDenimShirt
presidentOfTheUnitedStates
myPetCat
myCousinJimbo
This is about programming and understanding the difference about objects and class. Thanks

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…arrow_forwardCreate a House using Class python programming with the following properties and methods: floor size number of Floors number of Doors switchOn( ) lightOpen( ) ovenOpen( ) 2.

Fraction - an object that represents parts of a whole number. A fraction is created by supplying a numerator and a denominator. Instance related actions 1. add - mutates this fraction by adding the other fraction value 2. subtract - mutates this fraction by subtracting the other fraction value 3. multiply - mutates this fraction by multiplying with the other fraction value 4. divide - mutates this fraction by dividing by the other fraction value 5. tostring - represents the fraction in a form of 'numerator/denominator" 6. compareTo - returns the following values 1. O when this fraction is equal with the other fraction 2. 1 when this fraction is greater than the other fraction 3. -1 when this fraction is less than the other fraction Example fraction1 = 1/2 fraction2 = 3/4 When fraction1.add(fraction2] is called, it will make the value of fraction 1 as 5/4. When fraction1.subtract(fraction2) is called, it will make the value of fraction 1 as -1/4.…arrow_forwardThe following problem is based on a problem in a number of Java texts, including Gaddiss': Write a Temperature class that will hold a temperature in Fahrenheit and provides methods to get and display the temperature in Fahrenheit, Celsius, and Kelvin. The Temperature class should have the following instance variable: ftemp - A double that holds a Fahrenheit temperature. The Temperature class should have the following methods: ReadInput - Uses a Scanner method to populate ftemp with double value. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature. getCelsius - Returns the value of the ftemp field converted to Celsius. getKelvin - Returns the value of the ftemp field converted to Kelvin. DisplayOutput - The Fahrenheit temperature and the equivalent values in Celsius and Kelvin are gotten and displayed, one per line, and each along with an appropriate message. Use the following formula to convert the Fahrenheit temperature to Celsius: Celsius = 5.0/9.0 *…arrow_forward
