- Consider public class MyClass { public MyClass(){/code/} // more code… } To instantiate MyClass, you would write? MyClass mc = new MyClass(); MyClass mc = MyClass; MyClass mc = MyClass(); MyClass mc = new MyClass; public static int foo(int a, String s) { s = “Yellow”; a=a+2; return a; } public static void bar() { int a=2; String s = “Blue”; a = foo(a,s); System.out.println(“a=”+a+” s=”+s); } public static void main(String args[]) { bar(); } What is printed on execution of these methods? a = 4 s = Blue a = 5 s = Yellow a = 3 s = Yellow a =2 5 s = Blue What is true about private fields of a class? They must be used with private methods. They are accessible from anywhere inside or outside of a class. They can never be used in a class. They can be accessed only by methods inside the class they are associated with.Write a constructor for the IceCreamCup class. The constructor takes the name, and a List of Flavor s (name it fList) as parameters. It initializes the instance variables with the parameters. Use shallow copy for initializing the list of Flavor s. (Throw an IllegalArgumentException if the name is null, or the Flavor list is null or empty.) Note that successful instantiation should increase nCups by 1.Consider the code given below. #include using namespace std; class myclass { private: int x; public: myclass( ) { this->x=0; } void setX(int x) { this->x=x; int getX( ) const { return this->x; } } }; void main() { const myclass obj1; myclass obj2; obj1.setX(5); cout<Consider the following class definition and answer the following question. public class MyClass { /fields private int x; private int y; Ilconstructors public MyClass( ) {x = 0; y = 0; } public MyClass(int a, int b) { x = a; y = b; } I/methods public void ShowNumbers() { System.out.printin(x +" +y)B public void setx(int a) { x = a; public void sety(int b) { y = b; public int getx() { return x; public int gety() { return y; public int getsum() { return (x + y); public int getproduct() { return x*y; } Give the output created from the following segment written in the main method: MyClass Object1 = new MyClass( ); MyClass Object2 = new MyClass( 15, 20); Object1.ShowNumbers(); Object2. ShowNumbers();Consider the Speaker interface shown below: public interface Speaker{ public void speak();} For this problem, you will create 2 classes Human and Dog, both of which will implement the Speaker interface. The classes will not contain any properties; they will only implement the speak method, as dictated by the Speaker interface. The speak method will simply print a message in the "native language" of that speaker: For a Human, the speak method will print "Hello!" For a Dog, the speak method will print "Bark!"Consider the following class definition for class named MyClass and answer the following questions. public class MyClass { /fields private int x; private int y; llconstructors public MyClass( ) {x = 0; y = 0; } public MyClass(int a, int b) { x = a; y = b; } I/methods public void ShowNumbers( ) { System.out.printin(x +* +y)B public void setx(int a) { x= a; public void sety(int b) { y = b; } public int getx() { return x; public int gety() { return y; public int getsum() { return (x + y); public int getproduct() { return x*y; } a) Declare an object named MyObject using no arg constructor. b) Declare an object named MyObject with 20 and 30 as arguments.In this assignment, you will make two classes,Student and Instructor, that inherit from a superclass Person. The implementation of class Person is given below. public class Person{private String name;private int age; public Person(){name="";age=0;}/**Create a person with a given name and age.@param name the name@param age the age*/public Person(String name, int age){this.name = name;this.age = age;} /**Get the name.@return the name*/public String getName(){ return name;}/**Change the name.@param name the name*/public void setName(String name){ this.name = name;}/**Get the age.@return the age*/public int getAge(){ return age;}/**Change the age.@param age the age*/public void setAge(){ this.age = age;}/**Convert person to string form.*/public String toString(){return "Name: " + name + "\t" + "Age: " + age;}} You will also need to write a test program to test the methods you write for these two classes. The implementation details are described as follows. Stage 1:In the first file…The interface Speaker is describe below. public interface Speaker{ public void speak(); public void announce(String str); } Create classes Dog and Philosopher implementing the Speaker interface. (The code for the general overview of the classes are provided you just need to fill the method and class headers and their code) and then create a driver class showing the abilities of interface, these tests are includes the ability of creating an object of Dog and Philosopher with interface reference, testing their polymorphic ability with invoking the methods of interface. and showing how we can use a method of child class of interface (Pontificate for the case of philosopher) using casting. i will include the templates below which you will use to answer the question. you will just need to input the missing codes in the required spaces. //******************************************************************** // SpeakerTest.java Author: Lewis/Loftus // // Solution to Programming Project 10.3…Exercise 1 Consider the following definition of the class MyClass: public class MyClass { private static int count = 0; private int x; public MyClass(int i) { x = i; } public void incrementCount() { count++; } public void printX() { System.out.println("Value of x : " + x); } public static void printCount() { System.out.println("Value of count : " + count); } } public class MyClassDemo { public static void main(String[] args) { MyClass myObject1 = new MyClass(5); MyClass myObject2 = new MyClass(7); } } What is the output of the following Java code?
