| Ans. 1. for loop in java is used with a counter as following for(int counter=0;counter < 50;counter++){ System.out.println(list.get(counter)); } for iterating and printing the contents of a collection whereas foreach loop can be specified directly without the use of counter for(String str:list){ System.out.println(list.get(counter)); } 2. for Each loop syntax is more clean if we have to iterate over the elements of a collection and we need not keep track of the record count 3.
