Write a java program that calculate the product of the odd integers from 1 to 20

import java.io.*;
public class sample2 {


    public static void main(String[] args)throws IOException {
       BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

       int total=1;
       for(int x=3;x<=20;x+=2){
           total=total*x;
           
       }
        System.out.print("Product of odd integers is: "+total);
    }

}
