Question

Design the Xamarin Android Program to find the Volume of a Cylinder

Volume of Cylinder = 3.14 * radius*radius*height;

Display the output using a dialog box. Provide the input validation to accept numbers only

File coding is one should be xml file and another one is C# file for coding

Android coding

Answer 1

VolumeOfCylinder.java
import java.util. Scanner;

import javax.swing.JOptionPane;

public class VolumeOfCylinder {

public static void main(String[] args) {
//Scanner class object to get input from user
Scanner input=new Scanner(System.in);
System.out.print("Enter radius of cylinder: ");
// get radius of cylinder from user
double radius=input.nextDouble();
// validating radius
if(radius<0)
System.exit(0);
System.out.print("Enter height of cylinder: ");
// get height of cylinder from user
double height=input.nextDouble();
//validating height
if(height<0)
System.exit(0);
//calculate volume of cylinder
double volume=3.14* radius*radius* height;
//display answer using dialog box
System.out.println("\nVolume of cylinder is"+volume);
JOptionPane.showMessageDialog(null, "Volume of cylinder is "+volume);
input.close(); // close Scanner object
}
}
Output
Enter radius of cylinder:5
Enter height of cylinder:3

volume of cylinder is 235.5
