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
