Directly accessing Grandparent’s member in Java:
Predict the output of following Java program.
Output: Compiler Error
There is error in line “super.super.print();”. In Java, a class cannot directly access the grandparent’s members. It is allowed in C++ though. In C++, we can use scope resolution operator (::) to access any ancestor’s member in inheritance hierarchy. In Java, we can access grandparent’s members only through the parent class. For example, the following program compiles and runs fine.
Grandparent's Print() Parent's Print() Child's Print()
