How do I use two types in the method Generics, to sum only the areas of the classes Quadrado and Retangulo.
I tried a method like this:
public static double soma(Forma <? extends Quadrado> elementos) {
return elementos.getArea();
}
and Forma and abstract.

This is not possible in Java.
Quadrado and Retangulo inherit from Forma? Or does one inherit from the other? Well, if so, is a classic mistake. But let’s consider the first.
public static <T extends Forma> double soma(T elementos) {
return elementos.getArea();
}
I put in the Github for future reference.
What should do within the method I do not know since there is no information about it.
And where is there something being added up in the method soma?
@Victorstafusa I answered about the problem that of course, maybe I should close the question as unclear.
I already gave the first closing vote.

Talk more about the classes
Forma,QuadradoandRetangulo. What are their methods? The solution that I would come up with would simply not use any generic type, so I would like to see your classes to understand what these generic types are and what they represent.– Victor Stafusa
