Using class, constructor, object and methods display for the following:
The area of the circle when radius = 1 The area of the circle when radius = 25 The area of the circle when radius = 125 Hints: class Circle→ public: double radius → Construct a default circle object→ Construct a circle object → Return the area of this circle → main method (int main).

6. define a C++ class having the following members: (1) 2 instance methods the prototype of the first method is double funA(int r). The parameter r represents the radius of a circle. The funA will calculate the area of a circle and the value of its radius is from the parameter r. It will return the area of the circle. the prototype of the second method is double funB(int w, int h). The parameters w and h represent...

Write a java class definition for a circle object. The object should be capable of setting radius, and computing its area and circumference. Use this to create two Circle objects with radius 10 and 40.5, respectively. Print their areas and circumference. Here is the Java class file (Circle.java). Compile it. public class Circle{ //Instance Variables private double PI = 3.1459; private double radius; //Methods public Circle ( ) { } //get method (Accessor Methods ) public double getRadius (...

Create a class named Circle with fields named radius, diameter, and area. Include a constructor that sets the radius to 1 and calculates the other two values. Also include methods named setRadius() and getRadius(). The setRadius() method not only sets the radius, but it also calculates the other two values. (The diameter of a circle is twice the radius, and the area of a circle is pi multiplied by the square of the radius. Use the Math class PI constant...

Design and implement class Circle to represent a circle object. The class defines the following attributes (variables) and methods: 1. A private variable of type double named radius to represent the radius. Set to 1. 2. Constructor Methods: • Python : An overloaded constructor method to create a default circle. • C# & Java: Default Constructor with no arguments. • C# & Java: Constructor method that creates a circle with user-specified radius. 3. Method getRadius() that returns the radius. 4. ...

class Circle { private double radius; public Circle(double radius) { radius = radius; } } public Circle(double radius) { radius = radius; } } The program does not compile because Circle does not have a default constructor. The program will compile, but you cannot create an object of Circle with a specified radius. The object will always have radius 0. The program has a compilation error because it does not have a main method. The program has a compile error...

Complete the CashRegister class by implementing the methods and adding the correct attributes (characteristics) as discussed in class. Once complete, test the class using the CashRegisterTester class. Make sure you have 3 total items in the cash register. I have two classes, the first is CashRegisterTester below: public class CashRegisterTester { public static void main(String[] args) { //Initialize all variables //Construct a CashRegister object CashRegister register1 = new CashRegister(); //Invole a non-static method of the object //since it is non-static,...

Exercise 2: There can be several constructors as long as they differ in number of parameters or data type. Alter the program so that the user can enter just the radius, the radius and the center, or nothing at the time the object is defined. Whatever the user does NOT include (radius or center) must be initialized somewhere. There is no setRadius function and there will no longer be a setCenter function. You can continue to assume that the default...
