What are the main differences between different loops when it comes to coding ?

This question is relevant to different coding languages, and it can be easily explained using Java language : for instance, we will use an integer array called FOR:for(int i=0;i<ArrayList.size();i++) the same line can be expressed using an enhanced loop to iterate Java array called FOR EACH:for(integer number : ArrayList) Both loops will go through each INTEGER element from the ArrayList, the first one having more flexibility.
