Solution
The OOP concept/mechanism employed in the code above is overloading. Overloading is a concept in OOP where two or more methods in the same class have the same name but different parameters. In the code above, the method "isFruitBearing" is overloaded. One version of the method takes no parameters and always returns false, while the other version takes a boolean parameter and returns the value of that parameter.
