Is it possible to do

Class triangle:public shape{. .... };
In java

Also what would a's value in main be in this thanks

Void Area(Int a, int b){a=a*b;}

Public static void main(){int a=10; int b=5; area(a,b); //at this point a=? 10 or 50}

The best way to answer questions like this is to write some code and run it. In a sense it's the *only* way to answer such questions, since any reply you get here leads inevitably to "but is that answer correct?".

Java - like any programming language - is very fussy, so I would second Darryl's suggestion that you look at Oracle's Tutorial. If you have specific problems with what you find there, or if the compiler gives you messages you can't understand, or the results of your experiments are paradoxical, then you'll have a specific question to ask here.
