Modify a dealership's Automobile class so it includes fields for an id (ID number), make, model, color, year, and mpg (miles per gallon). Include get and set methods for each field.
- Do not allow the ID to be negative or more than 9999; if it is, set the ID to 0.
- Do not allow the year to be earlier than 2005 or later than 2019; if it is, set the year to 0.
- Do not allow the miles per gallon to be less than 10 or more than 60; if it is, set the miles per gallon to 0.
Include a constructor that accepts arguments for each field value and uses the set methods to assign the values.
