null pointer exception in "rs.next()"

Re: null pointer exception in "rs.next()"
Your ArrayList's size is 1, then you call next() function twice. Exception will occur.
When you call the second time iter.next(), there is null pointer exception due to "null.next"
List tmpList = new ArrayList(); tmpList.add(new Long(1)); for (Iterator iter = tmpList.iterator(); iter.hasNext(); ) { iter.hasNext(); iter.hasNext(); }
Re: null pointer exception in "rs.next()"
Calling next() on an iterator when no more elements left should result in a NoSuchElementException not a NullPointerException.Originally Posted by conniesookie
Given very little information has been given, we are left to guessing and I can only guess rs refers to a ResultSet. What is null on the line that throws the Exception?
