Here is java program to calculate total surface area of Cylinder. We are using scanner class to take input from user in below program.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
package org.arpit.java2blog; import java.util.Scanner; public class TotalSurfaceAreaCylinderMain { public static void main(String[] args) { Scanner s= new Scanner(System.in); System.out.println("Enter the radius of cylinder :"); double r=s.nextDouble(); System.out.println("Enter the height of cylinder :"); double h=s.nextDouble(); double surfaceAreaOfCylinder= 2 * Math.PI * r * r + 2 * Math.PI * r * h; System.out.println("Total surface area of cylinder is: "+surfaceAreaOfCylinder); s.close(); } } |

When you run above program, you will get below output

4

Enter the height of cylinder :

3

Total surface area of cylinder is: 175.92918860102841

That’s all about how to calculate total surface area of cylinder in java.
