1 Each applet's flow of control goes through a sequence of standard methods:
  • public void init() { . . . }
  • executed once when applet is downloaded to the browser.
  • public void start(){ . . . }
  • executed each time the browser window is entered.
  • public void paint(){ . . . }
  • executed whenever you want to draw in the window or when browser needs to refresh window.
  • public void stop(){ . . . }
  • executed each time the browser window in exited.
  • public void destroy(){ . . . }
  • executed just before the applet exits.
2 There are also standard methods repaint (), which calls update(), which blanks out the old drawing and calls paint.
