 String e1;
       double e;
       for(int i=0; ng.hasNext();i++){
         e1=ng.next();
         e=Double.parseDouble(e1);
         guestNumbers[i]=e;
       }


System.out.println(guestNumbers[0]);
System.out.println(guestNumbers[1]);
System.out.println(guestNumbers[2]);
System.out.println(guestNumbers[3]);

hi i want to add all the elements to a double ie do

double sum =guestNumber[0]+ guestNumber[1]+ guestNumber[1] and so on untill the end off the arra2

System.out.println("total = " +sum);

It is clear, It is very simple do.

public class SummMass {

    public static void main(String[] arg) {
        double[] mass = {1.0, 2.3, 4.2, 2.0 , 7.9, 3.3};
        System.out.println("total = " +summ(mass));
    }

    private static double summ(double[] mass) {
        double summ = 0;
        for (double value : mass) {
            summ += value;
        }
        return summ;
    }
}
