    // This program calculates the volume of a cone
    import java.io.*;
    class number14{
        public static void main(String a[]) throws IOException{
            System.out.println("This program calculates the volume of a cone");
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("Enter the radius of the cone: ");
            double r = Double.parseDouble(br.readLine());
     
            System.out.println("Enter the height of the cone");
            double h = Double.parseDouble(br.readLine());
     
            double v = (1/3) * (3.14) * (r * r) * h;
            System.out.println("The volume of the cone is "+ v);
     
        }

    Welcome studet
    Please use code tags when posting code, help can be found here

    (1/3) = 0 (integer division, not double division)
    zero times any number is zero
