update : Java Glossary

Clear the area for the component to the background colour by doing a fillrect then paint. update calls paint directly. update routines are often overridden to eliminate the fillrect which will reduce flicker.

/**
* turn off background repaint, because we will paint
* the entire region in paint.
*
* @param g Graphics context on which we paint.
*/
public void update ( Graphics g )
   {
   paint( g );
   }

update does not typically call validate .

update also means to install a more recent version of a program where the newer version is free.
