The base class.

public class BaseClass {

    public void print() {
        System.out.println("Base class");
    }
}

public class DerivedClass extends BaseClass {

    public void print() {
        System.out.println("Derived class");
        super.print();
    }
}

What is the output of the code below?

BaseClass clazz = new DerivedClass();
clazz.print();
