Java code to average and total a set of numbers?

Answer 1

The below method is written in the assumption that, the n numbers are sent as an ArrayList of Integer values.

public void computeSumAndAvg(ArrayList lst){ Iterator itr = lst.iterator();

int sum = 0;

float average = 0;

int count = 0;

while(itr.hasNext(){ Integer val = (Integer) itr.next();

sum = sum + val.intValue();

count++; }

average = sum/count;

System.out.println("Sum is: " + sum) ;

System.out.println("Average is: " + average) ; }
