Question

Create a Circle class, with two private properties - radius and colour. Create a Main class, that will be used to instantiate and interact with your Circle class. In the Circle class, add a default constructor (no params) that will always create a green circle with a radius of 2 . Add a second overloaded constructor, which allows external classes to control the size of any new circle object. Add a third constructor, which allows the creation of circles of any size or color on object creation. Add getter methods for the two properties (this makes them read-only from outside) Add a getAr(ea method to calculate and return the total area of a circle object. Math.PI may be useful here... Add a toString() method that will return a description of a circle object, something like "Radius =2, Colour = Blue" In the Main class' PSVM method, write a program to create at least three circle objects (testing each constructor) and interact with the other class methods. Remember: No console printing should be done from within your Circle class.

Answer 1

To create a Circle class with private properties and interact with it in a Main class, follow the provided steps.

Step-by-step explanation:

To create a Circle class with private properties and interact with it in a Main class, you can follow these steps:

1. Create a Circle class and declare private properties 'radius' and 'color'.
2. Add a default constructor that sets the radius to 2 and color to green.
3. Add an overloaded constructor that allows external classes to set the size of the circle.
4. Add a third constructor that allows the creation of circles with any size or color.
5. Add getter methods for the radius and color properties.
6. Implement a getArea() method that calculates and returns the area of the circle using the formula Math.PI * radius^2.
7. Add a toString() method that returns a description of the circle object.

In the Main class' PSVM method, you can create multiple circle objects using the different constructors and interact with the Circle class methods to test their functionality.
