Assume you have created an inheritance hierarchy with the following classes: Class: Organization
Methods: getName(), getNumEmployees(), getTaxLiability()
Class: Nonprofit extends Organization
Methods: getAnnualContribution(), getTaxLiability()
Class: Commercial extends Organization
Methods: getTaxLiability()
In your implementation class, assume you create the following line of code.

Organization o = new Nonprofit();

Using this line of code, write additional code that will call the getAnnualContribution() method
