Write a program in Java to compute the following properties of automobiles: average gas mileage,

lowest price, the latest model. The program must have the following:

$$ A class named Automobile $($library$).$

$$ One constructor function that initializes the model year only.

$$ A method to set the gas mileage and price for the object variables.

$$ Three separate methods to compute the results $($average gas mileage, lowest price, latest

model$)$ and show the outputs.

$$ The Main function will stay in another class $($test or main class$)$ from where the

constructors and all other methods will be invoked through three objects named: sedan,

minivan, and truck.

$$ Inputs are to be taken inside the Main function from the keyboard. The program will show

the outputs on the screen.

Sample Input $($from keyboard$)$:

Enter the model year for sedan: $2012$

Enter the gas mileage for sedan: $35$

Enter the price for sedan: $20000$

Enter the model year for minivan: $2013$

Enter the gas mileage for minivan: $26$

Enter the price for minivan: $18000$

Enter the model year for truck: $2010$

Enter the gas mileage for truck: $21$

Enter the price for truck: $17000$

Sample Output $($on screen$)$:

Avg gas mileage: $27\mathrm{.}33$

Lowest price: $17000$

Latest model: $2013$ i am not allowed to use inheritance in this code and i have written a little bit of it as well package Objects;
