Concept explainers

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

2. Consider the BlackJackCard and PlayingCard classes.

a)Do these two classes have an is-a or has-a relationship?

b)Which class is the more general class?

c)Which class is the more specialized class?

d)Would the four methods from the general class be appropriate in the specialized class? Explain your answer.

e)Give one example of a method that might appear in the specialized class but not the more general class.

"Is-a" versus "Has-a"
A large program will often be built out of multiple classes. Often, these classes will have a "has a"
relationship. For example, a game program might include three classes: PlayingCard, Suit, and Rank. A
PlayingCard object has a Suit and has a Rank, which are handled in a Java program as instance
variables.
PlayingCard
- cardRank: Rank
cardSuit: Suit
+ setRank (Rank rank): void
+ setSuit (Suit suit): void
+ getRank (): Rank
+ getSuit (): Suit
Class Name
Data Fields
Methods
Less often, you might have two classes which have an “is a” relationship, where one class is a more
general class, while the second class is a more specialized version of the original class. A blackjack
program might have a BlackJackCard class which is a PlayingCard. Notice the relationship is not
symmetrical: every BlackJackCard is a PlayingCard, but not every PlayingCard is a BlackJackCard.

java programming language You are part of a team writing classes for the different game objects in a video game. 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. Also write a main method for each class in which that class is tested – create…

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.

In java language on netbeans design a console application that will print the game sales for a particular game in 2021. Use an abstract class named Games that contains variables to store the game name, game genre and the total sales. Create a constructor that accepts the game name, game genre and the total game sales as parameters. In this class also create get methods for the variables. The Games class must implement an iGames interface that contains the following: public interface iGames { public void printSales(); public String getGame(); public String getGameGenre(); public int getGameSales(); } Create a subclass called Game Sales that extends the Games class. The Games Sales class must contain a constructor to accept the game name, game genre and total game sales as parameters. Then, write code for the Print Sales method, which prints the game sales report for 2021. Finally, write a Use Games class to instantiate the Games Sales class.
