ResultSet Behaviour in Java

A ResultSet cursor is initially positioned before the first row;
the first call to the method next makes the first row the current row;
the second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call to the method next will implicitly close it.
A ResultSet object's warning chain is cleared when a new row is read.
Returns: true if the new current row is valid; false if there are no more rows
Throws: SQLException if a database access error occurs
