将 add() 方法覆盖到另一个 class Java 中的私有 Set<>？

Question

I have 2 Java files: File 1 is a given data structure class with methods for a Set and I am not allowed to modify this class at all. File 2 is a class I am making which overrides the add() function in File 1.

File 1

public class MySetClass<E> {
    private final Set<E> set = new HashSet<E>();  //is private

    public boolean add(E element){
        return set.add(element);
    }
 }

File 2

public class OverrideMySetClass<E> extends MySetClass<E> {
    @Override
    public boolean add(E element) {
        System.out.println("Overriden Add");
        return set.add(element);      //ERR: MySetClass<E>.set is not visible (I know it's bc it's private)
    }
}

My question is how do I add items to a set that's not visible to the method that should be overriding add() ?

Answer 1

You should be able to use super.add(element)

In the same way as this refers to the current object, super refers to its direct parent
