How do I use two types in the generics method, to sum only the areas of the Quadrado and Retangulo classes.
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 it is, is a classic error . But let's consider the first one.
public static <T extends Forma> double soma(T elementos) {
return elementos.getArea();
}
What you should do within the method I do not know since there is no information on this.
