Cylinder class java program demo.

In this post, we will create a Cylinder java class and a demo main program to calculate the volume of the cylinder.

Java Program

public class Cylinder {

 private double height;
 private double radius;

 /**
 * @param height
 * @param radius
 */
 public Cylinder(double height, double radius) {
 this.height = height;
 this.radius = radius;
 }

 /**
 * @return the height
 */
 public double getHeight() {
 return height;
 }

 /**
 * @param height the height to set
 */
 public void setHeight(double height) {
 this.height = height;
 }

 /**
 * @return the radius
 */
 public double getRadius() {
 return radius;
 }

 /**
 * @param radius the radius to set
 */
 public void setRadius(double radius) {
 this.radius = radius;
 }

 //calculating Volume of the cylinder
 public double calculateVolume() {
 return Math.PI * radius * radius * height;
 }
}

 

// Main class
public class CylinderMain {
 public static void main(String args[]) {
 // Creating two Cylinder objects
 Cylinder c1 = new Cylinder(5.0,3.5);

 Cylinder c2 = new Cylinder(15.0,5.5);

 System.out.println("--------------Output----------");
 System.out.println("Height of C1 = " + c1.getHeight());
 System.out.println("Radius of C1 = " + c1.getRadius());
 System.out.println("Volume of C1 = " + c1.calculateVolume());

 
 System.out.println("Height of C2 = " + c2.getHeight());
 System.out.println("Radius of C2 = " + c2.getRadius());
 System.out.println("Volume of C2 = " + c2.calculateVolume());

 }
}

Output

————–Output———-
Height of C1 = 5.0
Radius of C1 = 3.5
Volume of C1 = 192.42255003237483
Height of C2 = 15.0
Radius of C2 = 5.5
Volume of C2 = 1425.4976665663685
