Hi...
if you can store 100,000 elements(or values) in arraylist ,How to get(or iterate) particular element(or value) from arraylist? and consider the performance issue .
And if there is a serious performance issue here, then perhaps the decision to use an ArrayList should be revisited. Using a Set makes the search an O(1) operation, instead of O(N) for an unsorted list and O(log N) for a sorted list.
