Question

I want to add items from a SQL table to an Java ArrayList. To get each item in the table, I am using the loop:

while(results.next())

However, I believe that this won’t quit the loop if there are no more results found unlike the .hasNext available from some classes and will cause an error of some sort. How would I get the while loop to quit if there is nothing else in the SQL table without causing an error?

Looking at the docs, i think it should work fine. Snippet from the docs:

Returns:
    true if the new current row is valid; false if there are no more rows

I hope you are talking about ResultSet
