Textbook Question
Chapter 8.2, Problem 11STQ
Rewrite the definition of the method reset for the class Undergraduate in Listing 8.4, using setName and setStudentNumber instead of the overloaded reset method name. (Most programmers would use the version in Listing 8.4, but you should be able to write either version.)

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.
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.
Copy your previous class definition for RectangularSolid from the previous problem, including both methods.
Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators).
These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.

- 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()}arrow_forwardChange the classes "Line" and "Matrix" as follows: a. all static properties of classes should be changed only inside class methods; b. select one or more sub methods (if it has not been done before) and arrange them as static methods.arrow_forwardWhat is method overloading?

- The following code is poorly structured. Rewrite it so that it has a better structure and avoids redundancy. To help eliminate redundancy, convert the code into a method named spending that accepts two parameters: a Scanner for the console, and a String for a single person's name, and prints the appropriate information about that person's bills. Your method could be called twice (once for John and once for Jane) to replicate the original code's behavior.arrow_forwardRedefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method.

- Please look at the images for the programming question. I am not sure sure where I should start on this. All coding is done in Java, using IntelliJ Idea.arrow_forwarddo the following question in javaarrow_forwardin c++ 3. Develop additional classes for Cat, Horse, and GuineaPig overriding the move() and speak() methods. (If you didn’t know, guinea pigs go “wheep wheepLinks to an external site.”). Make sure to also define a constructor and destructor for each of these classes, and that when you run your program, you can also see that the correct constructors and destructors are being called. Recall that a derived class will always call the parents constructors and destructors, so if you see this behavior, that is okay. Just make sure you are also calling the derived class’ constructors and destructors. Test with the modified main: int main (){Mammal* theArray[5];Mammal* ptr;int choice;for (int i = 0; i < 5; i++){cout << "(1)dog (2)cat (3)horse (4)guinea pig: ";cin >> choice;switch (choice){case 1: ptr = new Dog;break;case 2: ptr = new Cat;break;case 3: ptr = new Horse;break;case 4: ptr = new GuineaPig;break;default: ptr = new Mammal;break;}theArray[i] = ptr;}// Iterate through…arrow_forward
- What exactly is method overloading? Is it OK to declare two methods with the same name but distinct argument types? Is it legal to declare two methods in a class with similar method names and argument lists but distinct return value types or modifiers?arrow_forwardsolve this asap and provide codearrow_forwardCreate, compile, and run a recursive program. Choose one of the labs listed below and program it. More details for the lab can be found in the first PowerPoint for Chapter 9. Make sure your code is recursive. You can think of recursive code this way: If you cut and paste a recursive method into another class, it should still run without problems. In other words, you cannot have any instance variables (class-level variables) that the method depends on. Choice 1 - boolean isPalindrome (String str) that returns true if the input string is a palindrome. Choice 2 - boolean find (string fullStr, string subStr) that tests whether the string subStr is a substring of fullStr Choice 3- int numDigits (int num) to determine the number of digits in the number num Choice 4 - double intPower (double x, int n) to compute x^n, where n is a positive integer and x is a double precision variable Choice 5-void printSubstr (String str) that prints all substrings of the input string.arrow_forward
