Four Level Inheritance

Class A defines Origin. Classes B, C, and D form a chain of inheritance (D extends C, C extends B, B extends A). Make D inherit from C so a D object can call Origin. Do NOT write a Main method.

The program prints the output shown in Expected Output.

Expected Output:

from A↵

= newline. The output ends with a newline — print one after the last line.
