What would be the effect of the following code: public class Body Part { } public class Leg extends Body Part { } Leg 1 = new BodyPart(); A compiler error because we can not use a different reference type than the variable declared type. O The code will compile but will result in a runtime error. O A compiler error because a subclass reference variable cannot be assigned a superclass object. O Nothing. The code will compile without any errors.

THIS NEEDS TO BE DONE IN C#! Modify the code below so that the base class is an abstract class. class Pokemon{ protected string Name; protected string Type; protected string Health; public override void Attack() { //body of Attack } } Make Attack abstract as well. You do NOT have to create a derived class.
Design and implementation of Java (Draw UML) classes 1. Design a class named Bill to represent a square. 2. The class contains: • One data field called “Items” that defines the number of items. Another double data field called "price" defines the price. The default is 1.0. • no-arg constructor • constructor with parameters to create the invoice • method called getBill () that returns the item and price duplication. 3. Create a class and test a class (create three different objects and print the values of the variables and method)

Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…
The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A sloth eats and sleeps.*/class Sloth : public Critter{public:Sloth();. . .private:. . .}; Sloth::Sloth(){. . .} void Sloth::act(){if (...) {add_history("eat");...}else{add_history("sleep");... }} int main(){Sloth sloth;sloth.act();cout << sloth.get_history() << endl;cout <<…
