Lesson: 19 | The average of the elements of a List

EXPECTED OUTCOME

The average of the elements of the list is 6.

SOLUTION

List<Integer> myList = new List<Integer>{5,1,9,11,2,4,7,9};

Integer sum = 0;
for(Integer i=0; i<myList.size(); i++){
    sum += myList.get(i);        
}

Decimal average = sum / (Decimal)myList.size(); // typecast to Decimal to get a decimal average
System.debug('The average of the elements of the list is ' + average);
