Create a class named Vehicle that simulates a car moving along a 40 block stretch of road. Your class will build a vehicle and keep track of its location on the road. Location values may range from -20 to 20. A location value of 0 represents block 0, a location value of 1 represents block 1, a location value of 2 represents block 2, etc. If the …
