- Which is true given classes Boat and Car both derived from Vehicle ? a Boat reference can be automatically converted to Vehicle reference automatic conversion is not an option a Boat reference can be automatically converted to Car reference a Vehicle reference can be automatically converted to Boat referenceA 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…Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.

- Solve this question using java language. you have to read the information from a file then print them in a file please read the instructour carefully, also look at the attach images to help you to solve it. This tips will help you What You Must Implement:You must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media…Java Program This assignment requires one project with two classes.

Gremlins inherits how a monster eats. Gremlins speaks differently. Gremlins replace each word in a sentence with its only known language, "gar". For example, if the sentence is "I like chicken", the speak() method will turn it into "gar gar gar". class Monster { constructor(language){ this.language = language; this.stomach = Array(); } // takes a food_item STRING and returns everything eaten so far ARRAY eat(food_item) { this.stomach.push(food_item); } // takes in a sentence STRING and returns the passed in sentence STRING with no change speak(sentence) { returnsentence; } }
- Java Programming Create your own class that illustrates the use of encapsulation. Make sure to include at least one setter and one getter for the classRo-Sham-Bo. Believe it or not, the classic game of Rock-PaperScissors has many other names. One of them is Ro-Sham-Bo. For this assignment, “Ro” will represent “Rock”, “Sham” will represent Paper, and “Bo” will represent Scissors. You will create a RoshamboPlayer class. It will have three attributes: PlayerName: String RoLimit: int ShamBoLimit: int It will also have an overloaded constructor that sets those three values. It will have two functions: playRound that takes in a string and returns a boolean value, and getName that takes in nothing and returns the PlayerName string. In your driver class for this assignment, you will create two RoshamboPlayer objects with the following values: p1: RoLimit == 30, ShamBoLimit == 60 p2: RoLimit = 40, ShamBoLimit = 85 You may name them whatever you like. You will prompt the user to choose one of these two to play against. Then you will create a loop that prompt the user to either play a round of Roshambo, or quit the game. If the user chooses…
