10.4 (THE MYPOINT CLASS) Design a class named My Point to represent a point with x- and y-coordinates. The class contains: · The data fields x and y that represent the coordinates with getter methods. · A no-arg constructor that creates a point (0, 0). · A constructor that constructs a point with specified coordinates. · A method named distance that returns the distance from this point to a specified point of the MyPoint type. · A method named distance that returns the distance from this point to another point with specified x- and y-coordinates. · A static method named distance that returns the distance from two MyPoint obiects

9.19 LAB: BankAccount class (EO) Build a class called BankAccount that manages checking and savings accounts. The class has three private member fields: a customer name (String), the customer's savings account balance (double), and the customer's checking account balance (double). Implement the following Constructor and instance methods: public BankAccount(String newName, double amt1, double amt2) - set the customer name to parameter newName, set the checking account balance to parameter amt1 and set the savings account balance to parameter amt2. (amt stands for amount) public void setName(String newName) - set the customer name public String getName() - return the customer name public void setChecking(double amt) - set the checking account balance to parameter amt public double getChecking() - return the checking account balance public void setSavings(double amt) - set the savings account balance to parameter amt public double getSavings() - return the savings account balance…
13.5 (Enable GeometricObject comparable) Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger of two GeometricObject class. Also, draw the UML diagram and implement the new GeometricObject class. Additionally, write a test program that use the max method to find the larger of two circle, the larger of two rectangles.
10.11 C++ The base class Pet has protected data members petName, and petAge. The derived class Cat extends the Pet class and includes a private data member for catBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Cat pet, use PrintInfo() to print information, and add a statement to print the cat's breed using the GetBreed() function. Ex. If the input is: Dobby 2 Kreacher 3 Scottish Fold the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: Scottish Fold
7.21 LAB: Random values use Java. In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3(). Then write the following 2 instance methods: setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive). getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output may be: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range. import java.util.Scanner; public class LabProgram {// main method used to test your codepublic…

7.21 LAB: Triangle area comparison (classes) Given class Triangle (in files Triangle.h and Triangle.cpp), complete main() to read and set the base and height of triangle1 and of triangle2, determine which triangle's area is larger, and output that triangle's info, making use of Triangle's relevant member functions. Ex: If the input is: 3.0 4.0 4.0 5.0 where 3.0 is triangle1's base, 4.0 is triangle1's height, 4.0 is triangle2's base, and 5.0 is triangle2's height, the output is: Triangle with larger area: Base: 4.00 Height: 5.00 Area: 10.00
9.44 LAB: Book information (overriding member methods) Given main() and a base Book class, define a derived class called Encyclopedia with member methods to get and set private fields of the following types: String to store the edition int to store the number of pages Within the derived Encyclopedia class, define a printInfo() method that overrides the Book class' printInfo() method by printing the title, author, publisher, publication date, edition, and number of pages. Ex. If the input is: The Hobbit J. R. R.

Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…

C++ 2. Define a new "Degree" class that contains a year (integer), a subject (string), and a person’s name (string). For example, a degree can have "John Smith", 2020, and "Computer Science" It should have at least the following methods:- toString method must return all the degree information: year, subject, and person’s name.Here is an example of the formatted degree string:NAME(John Smith) SUBJECT(Computer Science) YEAR(2020) - hasTheSameDegree method compares 2 degrees and returns true if both have the same year and the same subject. Otherwise, it returns false. - isLater method that compares 2 degrees and returns true if the current degree has the year later than the 2nd degree and false otherwise. Important notes: - You can add as many other methods as you need. But this class should not provide the default constructor. - Show how this class and its methods are being used, called, and produce the correct results.

(Java) Q 1,2 ANSWER BOTH PART 1 AND 2!!! Explain the answer step-by-step and include verbal explanation. Thank you! PART 1: 1. Given the below Car class, write a child class of Car named Tesla. The Tesla class has an additional private boolean variable named autoPilotEnabled. It also has two constructors - a default constructor and a three argument constructor. Both constructors call the appropriate constructors of the parent class. Tesla also has a getter and setter for the autoPilotEnabled variable. Finally, it has a toString method that calls the toString of Car, as well as concatenating the autoPilotEnabled variable. 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)…
