Java programming. Create an Automobile class for a dealership. Include fields for an ID number, make, model, color, year, and 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.
Given code:
public class Automobile {
private int id;
private String make;
private String model;
private String color;
private int year;
private double mpg;
public Automobile(int id, String make, String model, String color,
int year, double mpg) {
}
public void setId(int id) {
}
public void setMake(String make) {
}
public void setModel(String model) {
}
public void setColor(String color) {
}
public void setYear(int yr) {
}
public void setMpg(double mpg) {
}
public int getId() {
}
public String getMake() {
}
public String getModel() {
}
public String getColor() {
}
public int getYear() {
}
public double getMpg() {
}
}
public class TestAutomobiles
{
public static void main(String[] args)
{
Automobile auto1 = new Automobile(1451, "Chevrolet", "Camaro", "red", 2010, 24.5);
Automobile auto2 = new Automobile(145188, "Ford", "Focus", "white", 2020, 75);
display(auto1, "good declaration");
display(auto2, "bad declaration");
auto1.setId(-3);
display(auto1, "bad ID");
auto1.setId(2222);
display(auto1, "good ID");
auto1.setMake("Toyota");
auto1.setModel("Corolla");
display(auto1, "change make and model");
auto2.setId(8686);
auto2.setColor("blue");
auto2.setYear(2016);
display(auto2, "change ID, color, and year");
auto2.setMpg(4);
display(auto2, "bad mpg");
auto2.setMpg(30);
display(auto2, "good mpg");
}
public static void display(Automobile auto, String msg)
{
System.out.println(msg + " " + auto.getId() +
" " + auto.getMake() + " " + auto.getModel() +
" " + auto.getColor() + " " +
auto.getYear() + " " + auto.getMpg() + " miles per gallon");
