I need to have a main method in a Tester class that will:  Fill an array of type Vehicle[] of size NUM_VEHICLES with Vehicle objects. You need to generate a random number between 0 and 2. If the number is 0, add a Vehicle to the array. 1, add a Car, 2, add a Boat. The Vehicle/Car/Boat that you add must be initialized with a random efficiency between 0 and 100.0. Do this until you have added NUM_VEHICLES objects to the array
