Every cylinder has a base and height, where the base is a circle. Design the class Cylinder that can capture the properties of a cylinder and perform the usual operations on a cylinder. Derive this class from the class Circle (done through Problem 3.2). Please do the following: Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Write a test program to test your program. Note: Java programming. Please also send the test program so I can run it in dr java and learn. Use given code and design the class cylinder that can capture the properties of a cylinder and perform the usual operations on a cylinder. Point code: // class Point public class Point { protected double x, y; // coordinates of the Point //Default constructor public Point() { setPoint( 0, 0 ); } //Constructor with parameters public Point(double xValue, double yValue ) { setPoint(xValue, yValue ); } // set x and y coordinates of Point public void setPoint(double xValue, double yValue ) { x = xValue; y = yValue; } // get x coordinate public double getX() { return x; } // get y coordinate public double getY() { return y; } // convert point into String representation public String toString() { return "[" + String.format("%.2f", x) + ", " + String.format("%.2f", y) + "]"; } //Method to compare two points public boolean equals(Point otherPoint) { return(x == otherPoint.x && y == otherPoint.y); } //Method to compare two points public void makeCopy(Point otherPoint) { x = otherPoint.x; y = otherPoint.y; } public Point getCopy() { Point temp = new Point(); temp.x = x; temp.y = y; return temp; } // print method public void printPoint() { System.out.print("[" + String.format("%.2f", x) + ", " + String.format("%.2f", y) + "]"); } } // end class Point Circle code: public class Circle { //declaring data members protected double radius; protected Point center; //constructor public Circle() { radius=0; center=new Point(); } //parameterized constructor public Circle(Point p, double radius) { center=p; this.radius=radius; } //getters and setters for radius public double getRadius() { return radius; } public void setRadius(double radius) { this.radius=radius; } //getters and setters for center public void setCenter(Point p) { center=p; } public Point getPoint() { return center; } //finding area public double getArea() { return 3.14*radius*radius; } //finding circumference public double getCircumference() { return 2*3.14*radius; } }
