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

For me, it's clear, the main advantage is readability.

for(Integer i : list){
   ....
}

is clearly better than something like

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