Java question

Define a class called Odometer that will be used to track fuel and mileage for an automobile. The class should have member variables to track the kilometres driven and the fuel efficiency of the vehicle in kilometre per litre. Include set methods to reset the odometer to zero kilometres, to set the fuel efficiency, to accept kilometres driven for a trip and adds it to the odometers total, and a get method that returns the number of litres of petrol that the vehicle has consumed for a trip.

Use your class with a test program that creates several trips with different fuel efficiencies and display the number of litres of petrol the vehicle has consumed since the odometer was last reset. You should decide which variables should be public, if any.
