Can you implement an interface in your class? A solution is placed in the
"solution" section to help you, but we would suggest you try to solve it on
your own first.
Problem Statement#
You are given an interface Addition which contains a method signature int
add(int num1, int num2). You need to write a class called Calculator which
implements the Addition interface.
The add(int, int) method takes two integers and returns their sum.
Input#
Calls the add(int, int) method by passing num1 and num2.
Output#
Returns the addition of num1 and num2.
Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)
Not all dogs like to bark, but some like to make a lot of noise! In this exercise we have a Dog superclass and a LoudDog subclass. You do not need to modify the Dog class. Your task is to write two override methods in the LoudDog class. You will override the speak method to return BARK!. You will then override the toString so that it returns Clover is loud and likes to BARK! where Clover is replaced by the name variable. Create and print at least one Dog and one LoudDog to test.
public class DogTester{public static void main(String[] args){// Start here}}
public class Dog{private String name;public Dog(String name){this.name = name;}public String getName(){return name;}public String speak(){return "Bark!";}public String toString(){return name + " likes to " + speak();}}
public class LoudDog extends Dog{public LoudDog(String name){super(name);}// Override the speak method here//Override the toString here.//Remember, you can access the name using super.getName()}

- Assume B is a subclass of A. Which of the statements about the following assignment is false? A a = new B(); We can assign anything to variable a that has a subtype of B. We can call on a any method defined in A. We can call on a any method defined in B. We can assign anything to variable a that has a subtype of A.arrow_forwardAdd a toString() method to Fraction class that returns the fraction as aString in the form "x / y", where x and y are numerator and denominatorrespectively. As the method does not do any display itself, the output can be done by a client program that calls the method in an output statement. Use client program to test this functionality; i.e. provide an output statement to display a fraction as its String representation. class Fraction2{private int n, d;public Fraction(){this.n = this.d = 0; //Initialize the values}public Fraction(int n, int d){this.n = n; //Initialize the variablesthis.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;} //Define the getter function getDen() that returns the denominatorpublic int getDen(){//Returns denominatorreturn d;}//Define the boolean function isZero() that returns 0 if numerator is 0 and denominator is not equals to zeropublic boolean isZero(){return(getNum() == 0 &&…arrow_forwardCan someone help in java Create a class Hotel with member data, hotel name and category (number of stars).For the Hotel class, write the standard methods (constructors, get & set, toString ()) and the getWiFi () method, which returns the wifi address formed by the first 4 letters of the hotel name and any number (you can get it with the random number generator) .In main (), illustrate the use of the Hotel class. Create a PopulatedHotel class, successor to the Hotel with an additional ArrayList <> field on behalf of the hotel guests.For the PopulatedHotel class, write standard methods (constructors, get & set, toString ()), with the get and set methods working with separate elements of ArrayList <>. For the PopulatedHotel class, also write methods for adding and removing a guest and a method for checking that a person is staying at the hotel. In main (), illustrate the use of the PopulatedHotel class.arrow_forward
- Write a class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25). Implement a constructor that takes both values as parameters. Implement accessors for both values. Implement a toString() that returns a string in the format “Name(number)”, e.g. “Pikachu(25)”. Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number.(remember the equals and hashCode contract).arrow_forwardWrite a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the following example: NumberGuesser *ng = new NumberGuesser(1, 10);cout <<…arrow_forward1. Write a java class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25).

Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number. (remember the equals and hashCode contract). 2. Create a java class, PokemonComparator, that implements Comparator and compares two Pokémon in reverse order by number. For example, if Pokemon A's number is 25 and B's number is 50, compare(A, B) would return a number > 0 because B should come first. Hint: what if you subtracted the numbers? 3.

Insert at least 10-15 more Pokémon in any order. c.…arrow_forward
- Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and arraylist of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array. The main function that does these things looks as follows: Public static void main(Strings[] args) { Item shampoo2(“pantene”, “Procter & Gamble”,100), noodles(“Noodles”, “knorr”, 50); // add further items. Store abcSuperStore; abcSuperStore.add(shampoo2); abcSuperStore.add(noodles); … abcSuperStore.sale(shampoo2); a bcSuperStore.sale(noodles);arrow_forwardImplement a superclass Person.
