How can i refresh JFrame at regular intervals to display in intervals

Question

I have a query which is :
String query = "select FIRSTNAME, MIDDLEINITIAL, LASTNAME from user" ;
now i have executed the above query
ResultSet rs = stmt.executeQuery(query) ;
Suppose i get 2000 rows in my resultset after execution.
If i want to display all the contents of my query inside a JFrame, then i can say
JFrame myFrame = new JFrame() ;
myFrame.setSize(500, 500) ;
while(rs.next()){
add the results to myFrame
myFrame.pack() ;
myFrame.setVisible() ;
but this may take a long time to show my frame, because first it has to either add components to my JFrame if use JLabels or if i use graphics then it has to wait till complete all of my drawString's to display the JFrame.
and this may take time.
I would like to know, how can make my JFrame intelligent enough so that if first display an empty frame, refresh at regular intervals and see how many i have fetched from the result set and add those to my JFrame, and do this opration untill i am done fetching all the results.
Thanks

Any reason why you aren't displaying the results in a table? Both labels and drawString do not seem like a good alternative.
Now to your question, you could use a thread and force painting after so many from the resultset. You could display a fixed number and implement your own scrolling scheme. Say paint first 50 and scrolling forward and back.
