Fibonacci A fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on… For this, you will implement a class that takes a positive integer (n) and returns the number in the nth position in the sequence. Examples When n is 1, the returned value will be 0. When n is 4, the returned value will be 2. When n is 9, the returned value will be 21. come up with the formula and base cases Implementation Create a class Fibonacci with a public static method getValue. Create a Main class to test and run your Fibonacci class.
Assume the Book class is defined as follows: public class Book{ enum Type type {FICTION,NON_FICTION}; public int isbn; public Type type; Book(int isbn, Type type){ this.isbn = isbn; this.type = type; }} Define filterBooksOfGivenType method that shall return ArrayList of Book of the type specified in parameter.
The BankAccount class described below is used to represent a personal savings account with a yearly interest rate, (represented as a percentage, e.g., a 7% rate is represented by .07). The interest is applied monthly, (i.e., at the end of each month 1/12 of the interest is deposited into the account). public class BankAccount { public BankAccount(double rate) public BankAccount(double initBal, double rate) public double getBalance() public double getIntRate() public void setIntRate(double rate) public void deposit(double amount) public void withdraw(double amount) public void addMonthsInterest() private double balance; private double intRate; } Suppose a bank offers to its special customers a new type of savings account, called a “Credit Account”, that allows the customer to withdraw extra money if needed, so that the account balance is allowed to be negative at some times. These accounts award interest at the end of every month, as long as the balance is positive. If the…
(Java) Question 5,6 ANSWER BOTH PART 1 AND 2!!! Explain the answer step-by-step and include verbal explanation. Thank you! Given the below Car class, update the default constructor so that it calls the two argument constructor. public class Car { private String make;private String model;public Car() {make = "Make unknown";model = "Model unknown";}public Car(String make, String model) {this.make = make;this.model = model;} public String getMake() {return make;}public String getModel() {return model;}public void setMake(String make) {this.make = make;}public void setModel(String model) {this.model = model;}public boolean timeForService(int currMileage) {if (currMileage < 10000) {return true;}return false;}@Override public String toString() {return "Make: " + make + "\nModel: " + model;}} PART 2 Next, override the equals() method for the above Car class using the formula provided in class.

Chapter 7. PC #1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Main class name: RainFall (no package name) PLEASE MODIFY THIS CODE SO WHEN I UPLOAD IT TO HYPERGRADE IT PASSES THE TEST CASES. IT HAS TO PASS THE TEST CASES BECAUSE WHEN I UPLOAD IT TO HYPERGRADE IT DOES NOT PASS THE TEST CASES. I HAVE PROVIDED PROOF OF THE PART OF THE TEST CASE THAT FAILED. import java.util.Scanner;public class Rainfall{ double rain[]; public Rainfall() { rain = new double[12]; } public double averageRainfall() { return getTotalRain()/12.0; } public double getTotalRain() { double total = 0.0; for(int i=0;i<12;i++)…
Imagine a publishing company that markets both book and audiocassette versions of its works. I it markets both book and audiocassette versions of its works. create a class called publication that stores the title (a string) and price (type float) and date of a publication. Provide getters/setters and constructor also write an abstract method isOversize() .From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of the classes should have a getter/setters and constructors and provide definition to function called isOversize() to the book and tape classes. Let’s say that a book with more than 800 pages, or a tape with a playing time longer than 90 minutes (which would require two cassettes), is considered oversize. You can access this function from main() and display the string “Oversize” for oversize books and tapes when you display their other data. explain the working in your words

CLASS AND OBJECT WRITE! 1.) Write the main class of the given class Animal below that set the number of legs to “4” and display (get) the number of legs. class Animal { private int numberOfLegs; public void setNumberOfLegs(int numberOfLegs) { this.numberOfLegs = numberOfLegs; } public int getNumberOfLegs() { return numberOfLegs; } }
Define a class named Doctor whose objects are records for a clinic’s doctors. Derive this class from the class Person given in Listing 8.1. A Doctor record has the doctor’s name—defined in the class Person—a specialty as a string (for example Pediatrician, Obstetrician, General Practitioner, and so on), and an office-visit fee (use the type double). Give your class a reasonable complement of constructors and accessor methods, and an equals method as well. Write a driver program to test all yourmethods.
