Inheritance
Given the following two classes...
abstractpublicclass A{
public String element ="A";
void test(){
System.out.println("A's method: " + element);
}
}
and
publicclass Cextends A{
public String element ="C";
publicstaticvoid main(String[] args){
C c =new C();
c.test();
}
}
I get "A's method: A" as output
My question is, since C inherits the methodtest, why doesn't the program output the member "element" from C? And is there a way of using A's method with C's member variable?

No, but why is C declaring an attribute with the same name? Just assign a value to the A.element instead.

You shadow the variable element in C. That means that C isn't accessing the inherited version's, it's using it's own. Since the test method is only defined in the A class, it can't print C's version of the variable. Try giving C a constructor and setting element = "C"; without declaring it as a new variable.
public C() {
element = "C";
}
