JDBC Insert - Interesting!!

Question

In JDBC 2.0 we can insert/update using programming language Java.
For an insertion, we do (assuming table name:COFFEES)
---other code here-----
ResultSet uprs = stmt.executeQuery("SELECT * FROM COFFEES");
uprs.moveToInsertRow();
uprs.updateString("COF_NAME", "Kona");
uprs.insertRow();
why do we have to call a moveToInsertRow()? Anyways the row is going to get inserted somewhere in the table and resultset. what difference does it make?
