- Create a class IntArray. Create two constructors. Nullary constructor create an array of size 10 and initiazes all values to 0. Parametrized constructor has signature IntArray(int num, int s). Thiscreates an array of size s and initializes all values. c++6. Given: class Pet { public: virtual void eat() { cout eat(); } What is the result of compiling and running the above program? m. The program compiles and crashes when it runs. i. The program compiles and runs, printing "Pet::eat" j. The program compiles and runs, printing "Cat::eat" The program compiles and runs to completion without printing anything. n. o. None of the above. k. The program fails to compile because the method eat is not marked virtual in Cat. I. The program fails to compile for some other reason.Which is illegal.Single choice. public class classA extends classB public class classA extends classB,classC public class classA implements interfaceA public class classA implements interfaceA,inetrfaceB

- Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…#2 The following code segment is an example of public int min(int a, int b, int c) { . } public int min(int a, int b, int c, int d) { ...} Answer polymorphism overloaded method overriding method interfacesCan you please help me with this, its in java.

Have heapArray hold maxSize of 250 entries. Also, include the methods: default constructor, toString. c) Create HeapOverflowException and HeapUnderflowException classes d) Create a Heap Demo class that creates a HeapPriorityQueue object and insert the values 1-10 into the heap. Print out the heap and remove two values from the heap. Print the resulting heap. Try and show the resulting tree with the nodes on their appropriate levels along with their branches.a:) Define a Polygon interface that has methods area() and perimeter(). b:) Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. c:) Implement classes, IsoscelesTriangle, Equilateral-Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. d:) Write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then output their area and perimeter. e:) For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar. using all a to e parts develop a program
