Exception in thread "main" java.util.NoSuchElementException

[ragav]

Hi i am using hashmap to store key & value pairs

Before iterating thru hashmap i am checking !map.isEmpty() in
while(!map.isEmpty() && iter.hasNext())
It shows below error..
Exception in thread "main" java.util.NoSuchElementException

how to resolve this.

Thanks

I wonder if you are calling one iter.next() more than once from within the while loop? What does the code within your loop look like?

Thanks for ur reply..
The below is my code snippets
while(iter.hasNext()){
while(rs.next()){
selecting values from map
insert into table with map values
}
}

given what you've posted, I have no idea. What is "rs" for instance? Why does it appear that you are not using your iterator even though you are first checking it in the first while condition?...

Thanks for ur reply..

I am using iterator for selecting value from map..
Using rs.next() i am selecting value from one table
and then insert both values (from hashmap & table ) into another table..
