What are the Advantages of Enhanced for loop and Iterator in Java?

Question

can anyone please specify to me what are the advantages of Enhanced for loop and Iterators in java +5 ?

Answer 1

The enhanced for-loop offers the following main advantage:

for (int i=0; i <= list.size(); i++)

It eliminates the repeated calculation of list.size() on every iteration in the non-enhanced version above. This is a performance advantage that matters.

Alternatively, you may calculate the size outside the loop as follows using an additional variable:

int size = list.size();
for (int i=0; i <= size; i++)
