Lesson: 66 | Identifying Even Numbers in a List

Expected Outcome

 The even numbers in the list are: (2, 4, 14)

Solution 1

List<Integer> myList = new List<Integer>{5, 1, 9, 11, 2, 4, 7, 14};
List<Integer> evenList = new List<Integer>();

for(Integer num : myList){
    if(Math.mod(num,2) == 0){
        evenList.add(num);
    }
}

System.debug('The even numbers in the list are: ' + evenList);

Solution 2

List<Integer> myList = new List<Integer>{5, 1, 9, 11, 2, 4, 7, 14};
List<Integer> evenList = new List<Integer>();

for(Integer i = 0; i < myList.size(); i++){
    if(Math.mod(myList[i],2) == 0){
        evenList.add(myList[i]);
    }
}

System.debug('The even numbers in the list are: ' + evenList);
