- (Java) Question 5 Explain the answer step-by-step and include verbal explanation. Thank you! Write an interface as follows: The interface is named ServiceReminder It has one method named timeForService that has no parameters and returns a boolean variable. Now, update the below class so that is inherits from ServiceReminder Note that the next service date should be 90 days from the last service public abstract class Car { private double gasGauge; private double currMileage; private String color; private String make; private String model; private int daysLastService; public Car(String color, String make, String model, int daysLastService) { this.color = color; this.make = make; this.model = model; gasGauge = 0.0; currMileage = 0.0; this.daysLastService = daysLastService; } @Override public String toString() { return "Make: " + make + "\nModel: " + model + "\nColor: " + color…(Triangle class) Design a new Triangle class that extends the abstract Geometricobject class. Draw the UML diagram for the classes Triangle and Geometricobject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filed. The program should create a Tri- angle object with the se sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.(The Account class) Account -id: int -balance: double -annualInterestRate : double -dateCreated : Date +Account( ) +Account(someId : int, someBalance : double) +getId() : int +setId(newId : int) : void +getBalance() : double +setBalance(newBalance : double) : void +getAnnualInterestRate( ) : double +setAnnualInterestRate(newRate : double) : void +getDateCreated( ) : Date +getMonthlyInterestRate( ) : double +getMonthlyInterest( ) : double +withdraw(amt : double) : void +deposit(amt : double) : void Design a class named Account that contains: ■ A private int data field named id for the account (default 0). ■ A private double data field named balance for the account (default 0). ■ A private double data field named annualInterestRate that stores the current interest rate (default 0).

- LocalResource(String date, String sector)- Actions of the constructor include accepting a date in the format “dd/mm/yyyy”, initializing the base class, storing the sector and storing an id as a consecutively increasing integer. Note that the constructor must ensure that the date of birth information is recorded. b. getId():Integer - returns the ID of the current instance of LocalResource c. getSector():String – returns the sector associated with the current instance of localResource d. getTRN():String – returns the trn number of the current instance of LocalResource. The process used to determine the TRN is to add the id to the number 100000000 and then returning the string equivalent. e. Update the NineToFiver class to ensure it properly extends the LocalResource class f. In method getContact() of NineToFiver, remove the comments so that the method returns "Local Employee #"+and the id of the contact. Write a concrete class LocalConsultant that extends LocalResource, and implements…Why do classes need destructors?Tape for a Turing Machine (Doubly-linked List)”.(I USE ECLIPSE & RUN CHECK ONLINE CONSOLE)A class named Tape to represent Turing machine tapes. The class should have an instance variable of type Cell that points to the current cell with the method: public Cell getCurrentCell() -- returns the pointer that points to the current cell. public char getContent() -- returns the char from the current cell. public void setContent(char ch) -- changes the char in the current cell to the specified value. Don't forget the Javadoc comments. IT WOULD HAVE A PUBLIC CLASS public void moveLeft() -- moves the current cell one position to the left along the tape. Note that if the current cell is the leftmost cell that exists, then a new cell must be created and added to the tape at the left of the current cell, and then the current cell pointer can be moved to point to the new cell. The content of the new cell should be a blank space. (Remember that the Turing machine's tape is conceptually…
- #pyhton programing topic: Introduction to Method and Designing class Method overloading & Constructor overloading ------------------ Question 1 Suppose your little sibling wants your help to check his math homework. He is done with his homework but wants you to see if all his results are correct. Since the student with all correct results gets 3 stars. However, you want your brother to check this on his own. So, you design a calculator for him in python. You could have given your scientific calculator but you wanted to give him a basic calculator and also wanted to see if you can even design one. Subtasks: Create a class called Calculator. Your class shall have 1 constructor and 4 methods, namely add, subtract, multiply and divide. Now, create an object of your class. After creating an object, it should print “Let’s Calculate!” Then take 3 inputs from the user: first value, operator, second value 5. Now based on the given operator, call the required method and…Why must classes implement destructors?Q:Define class Car according to the following: WRITE A CLASS , STEP BY STEP IN GAVA Car make - yearModel + setMake() + setYearModel() + getMake() + getYearModel()
- Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…Explain how the destructors of base and derived classes work.Talking: Heba Abde QUESTION 1: Implement class myTime, this class should: 1) Encapsulate information about the hours (integer), minutes (integer), seconds (integer), AM PM (String) 2) Forbid invalid times, where the following criteria should be considered: - hours are in the range [1 – 12], default is 12. - minutes are in the range [0 – 59], default is 0. - seconds are in the range [0-59], default is 0. - AM PM can only be either “AM" or "PM", default is "AM" If any forbidden value entered, you should set the value to default value. 3) Two different constructors (default and parameterized) 4) A print function that will print the time as (hours : minutes : seconds PM/AM) Example: 02:45:30 PM 6) implement function ticktack, which adds one to the seconds, notice that if seconds is 59 and you add one, it should become 0 and the minutes should be incremented by one, also, if after incrementing minutes by one it becomes 60, it should be set to 0 and hours must be incremented by 1, if after…
