Question
If you wish to delete items from an Array list you can use ... (multiple responses are allowed)a.a for-each loopb.a while loop with an iteratorc.a for loop with an Iteratord.any of the above
Solution
The correct answer is:
b. a while loop with an iterator
Explanation:
a. a for-each loop: This is not a good option because it can lead to ConcurrentModificationException if you try to modify the list while iterating over it.
c. a for loop with an Iterator: This is also not a good option because it can lead to ConcurrentModificationException if you try to modify the list while iterating over it.
d. any of the above: This is not correct because as explained above, using a for-each loop or a for loop with an Iterator can lead to exceptions.
The safest way to remove items from an ArrayList while iterating over it is to use a while loop with an Iterator. The Iterator's remove() method ensures safe removal of elements.
