Write static methods:
public static double cubeVolume(double h) : h^3
public static double cubeSurface(double h) : 6h^2
public static double cylinderVolume(double r, double h) : hπr^2
public static double cylinderSurface(double r, double h) : 2rπh+2πr^2
that compute the volume and surface area of a cube with height h, and a cylinder with circular base with radius r and height h. Place them into a class named “Geometry.java”. Then write a program with main class called “Lab7_yourID.java” that prompts the user for the values of r and h, calls the four methods, and prints the results.
(Optional) Reconsider your previous solution by implementing classes Cube, and Cylinder separately instead of a single class “Geometry” (part A). Which approach is more object-oriented?
Write the equals method for Circle2 which returns true when the radius and the color are the same as the parameter’s radius and color.
The TestCircle2, Circle2 and GeometricObject2 classes are given as follows.
public class TestCircle2 {
public static void main(String[] args) {
Circle2 c1 = new Circle2(2.3, "red");
Circle2 c2 = new Circle2(5.6, "white");
Circle2 c3 = new Circle2(2.3, "red");
System.out.println("c1 equals c2: " + c1.equals(c2));
System.out.println("c1 equals c3: " + c1.equals(c3));
System.out.println("c2 equals c3: " + c2.equals(c3));
}
