Answer 2

Java's most powerful features are for internet applications and socket connections. You can use these as web-page applets or better still as standalone applications. Socket connections allow applications and computers to communicate directly on any network (internet included) (or on a single computer).
People often complain that Java applets are slow. The reason for this is that the applet is a programme and it must download onto your computer (do not worry about security problems that you have with normal Windows technology - a Java applet cannot interfere with your computer). Once the small applet downloads onto your computer then the execution is extremely fast because everything is then happening on your computer not on a distant computer that you have to keep downloading from.
With server side applications it is a constant pain that every time you click on something you have to wait for a new web-page to download - you don't have this constant delay with Java applets.
Java is also convenient for creating internet games - much superior to Flash because you have access to a full blown programming language.
