Exercise (Section 30/40):
Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An
appointment has a description (for example, "see the dentist") and a date. Write a method
occursOn(int year, int month, int day) that checks whether the appointment occurs on that date.
For example, for a monthly appointment, you must check whether the day of the month matches.
Then fill an array of Appointment objects with a mixture of appointments. Have the user enter a
date and print out all appointments that occur on that date. Give the user the option to add new
appointments. The user must specify the type of the appointment, the description, and the date.
1. Write a java 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).
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. Write a new class, PokemonMain, with a main method that:
a. Creates a binary tree with your favorite Pokémon at the root and a new PokemonComparator.
b. Insert at least 10-15 more Pokémon in any order.

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_forward
- Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows: Income Tax Due $0 - $50,000 5% $50,000-$100,000 $2,500 + 10% of (income > $50,000) > $100,000 $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.arrow_forwardwrite the code in java.
