Expert Solution
Step 1

Program:

Filename: “Vehicle.java”

//Definition of class Vehicle

public class Vehicle{

    //variables to store manufacturer and owner

    private String manufacturer;

    private String owner;

   

    //setter method to set manufacturer value

    public void set_man(String m){

        manufacturer = m;

    }

   

    //setter method to set owner value

    public void set_own(String o){

        owner = o;

    }

   

    //getter method to get manufacturer value

    public String get_man(){

        return manufacturer;

    }

   

    //getter method to get owner value

    public String get_own(){

        return owner;

    }

}

Step 2

Filename: “Truck.java”

//Subclass Truck

public class Truck extends Vehicle{

    //variable to store mpg

    private int mpg;

   

    //setter method to set mpg

    public void set_mpg(int mp){

    mpg = mp;

    }

   

    //getter method to get mpg
