Inheritance-Print Alphabet

Write a Class A, the object created by the class can call the method F output lowercase English alphabet. Then write a subclass B of Class A, requiring subclass B must inherit the method F of Class A (not allowed to override), subclass B creates an object that can not only call the method F output lowercase English alphabet, but also can call the subclass new method G output uppercase English alphabet. Finally, the main class C is written, and Class A and Class B are tested in the main method of the Master class.
