Instructions: Declare an interface named Tool with a single method apply. The method has a single parameter of type int named minutes but does not return any value. Implement an abstract class named Drill). The class has a boolean variable and implements two methods turnon) and turnoff). Both have no parameters and do not return any values. Implement a class named PowerDrill. The class inherits from (Drill and implements the Tool interface. The apply method outputs a message "drilling for {X} minutes" where {X} is the minutes argument that is passed to the method, e.g. "drilling for 5 minutes"!
