What happens when my Java applet runs on older Java versions, but uses new classes? -

i creating applet embed in html page. applet uses grouplayout class, found in java se 6, not in 5.

when computer runs java 5 or before opens html page, happen? applet not run properly?

it throw classdefnotfounderror. avoid not utilize new api or utilize 3rd party api or "still" grouping layout: take class, alter package, include project , utilize it. can better. create instance dynamically using class.forname(). if succeeds utilize standard implementation, otherwise utilize stolen class. can because typically can utilize standard layoutmanager's api without using api of specific class loader.

java applet compatibility grouplayout
