Why am I getting errors?

Question

import java.util.Scanner;
public class CalcCircumference
{
public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("Do you want to use Diameter of Radius?");
System.out.println("Enter your choice");

String choice = input.nextLine();

if(choice.equalsIgnoreCase("Diameter"))
{
System.out.println("Enter Diameter");
int diameter = input.nextInt();
double circum = Math.PI * diameter;

System.out.println("Choice: Diameter");
System.out.println("Circumference = " + circum);

}

if(choice.equalsIgnoreCase("Radius"))
{

System.out.println("Enter Radius");
double radius = input.nextDouble();
double circum = Math.PI * Math.pow(radius, 2);

System.out.println("Choice: Radius");
System.out.println("Circuference = " + circum);

}

}
}

Answer 1

error?

Answer 2

whats the error given by compiler?
