Textbook Question
Chapter 5.3, Problem 27STQ
Write a method definition for a method called isGrowthRateLargeThan that could be added to the class Species in Listing 5.19. This method has one argument of type Species. The method returns true if the receiving object has a larger growth rate than the growth rate of the argument; otherwise, it returns false.

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.
Write a program that simulates the Magic 8 Ball game. The class should have a method that returns an answer at random. Test your class by outputting the answer several times.
Java Program Please
Write a method named equals that will be placed inside the Rectangle class. The equals method receives a Rectangle object rect as a parameter and returns whether the Rectangle rect has the same width and height as this Rectangle.

- Write a complete program for the description given below. Consider a Billing class that implements an interface Payable having a method getTotalPayment Amount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID. pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and Medical Test class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPayment Amount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in…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.

This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often.arrow_forward
