you can compare an Area to a Rectangle using:

Area a;
Rectangle r;

(boolean) a.instrects( r );

but how can a compare two area's two each other that are not exact
rectagles?

(don't say compare one area to the bounds of another because i need
more accuarcy then that)

Not tested, so use the idea at your own risk:

public static boolean intersects(Area a, Area b){
Area c = (Area)a.clone();
c.intersect(b);
return !c.isEmpty();
}
