Step by step
Solved in 2 steps
- JAVA CLASS AND OBJECT Modify the java program/code given below. 1.) Modify the abstraction example code below by adding another class “TestCarabao” with the necessary methods “label, move, and eat”. abstract class Animal { // abstract methods abstract void move(); abstract void eat(); // concrete method void label() { System.out.println("Animal's data:"); } }class Base { public: int x, y: public: Base(int i, int j) { x = i; y = j; }}; class Derived : public Base public: Derived (int i, int j) { x = i; y = j; void display() {cout « x <<" "<< y; }}; int main(void) { Derived d(5, 5); d.display(); return e; Error O X=5,Y=5 X-0,Y=0 None of the above Other:Consider the following code segment and answer questions 14 and 15. class Point { public: Point (double x = -99, double y = -99) { this -> xM = x; this -> yM = y;} double getx () {return xM; } double gety () {return yM; } void setx (double x) {this -> xM = x; } void sety (double y) {this -> yM = y; } private: double xM, yM; }; 14. What is the output of the following code snippet: Point pl (100); cout << pl.getx() << " " << pl.gety(); a. The output of the program is: -99 -99 b. The output of the program is: 100 100 c. The output of the program is: -99 100 d. The output of the program is: 100 -99 e. None of the above. It doesn't compile because constructor of Point needs two arguments. 15. How many times does the constructor of class Point get called by the following code snippet: Point a (100, 200); Point b[6]; Point *c = new Point; Point *d = new Point (300, 400); a. Four times b. Three times c. Nine times d. Two times e. None of the above

Write a program that creates a car object, and displays the year and name with one method “speed”. Example output: Year: 2021 Model: Toyota Speed: 200km/h 3.) 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; } }1) Draw a class diagram depicting the below code. class Doctor { void Doctor Details () { System.out.println("Doctor Details..."); } class Surgeon extends Doctor { void Surgeon_Details () { System.out.println("Surgen Detail..."); } } public class Hospital { public static void main(String args[]) { Surgeon s = new Surgeon (); } } } 2) Establish an association between Person class and Book Class given below. public class Person { } s. Doctor Details (); s. Surgeon Details (); } private String name; private int age; public Person (String initialName) { this.name = initialName; this.age = 0; } public void printPerson() { } public String getName() { return this.name; } System.out.println(this.name + age public class Book { private String name; private String publisher; private ArrayList authors; // constructor public ArrayList getAuthors() { return this.authors; } public void addAuthor (Person author) { this.authors.add(author); } + this.age + 11 years");

The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…
