Answer Posted / amit r
There are basic 3 differences between For and Iterater.
1.
Using Iterater we can check if the object exists or not by using hasNext method. Where as in For Loop, there is not such method. Therefore, For Loop will be executed at fixed amount at every time.
2.
Using Iterator we can add or remove objects from the underlying collection. In For Loop, if we do so, concurrent modification exception will be thrown.
3.
Using Iterator we can move forward or backward where as For Loop can't.
