All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.

public class Auto extends Vehicle
{
private String license Plate;
public Auto (String vin, String plate)
{
}
}
// TODO: Override the equals method of the Object class to
// test that VIN and license plate number are identical.
}
