For-each vs Iterator. Which will be the better option

Question

Consider the following scenario.

List list = new ArrayList<>();

Now I added the String values for this li

Answer 1

for-each is an advanced looping construct. Internally it creates an Iterator and iterates over the Collection. Only possible advantage of using an actual Iterator object over the for-each construct is that you can modify your collection using Iterator's methods like .remove(). Modifying the collection without using Iterator's methods while iterating will produce a ConcurrentModificationException.
