The best thing to happen to Java was Google supporting Android. Now we have probably 5 more years of this mess until we get good adoption of a real linux phone, then Java will be tossed onto the already rotting corpse of flash.
Hardly worth bothering to reply to this sort of nonsense, but applets are a tiny tiny fraction of a percent of what Java is used for. Java and other JVM languages are use in most backend systems today and also by the likes of google, amazon etc.
