Question

Problem Statement

A car dealer wants to use a software to display his or her cars’ information. As a software

developer, you are going to develop a simple program for the dealer. You will have a Car class

which has the following member variables:

 Car’s Brand

 Car’s Color

 Car’s MPG (Mile Per Gallon)

This class has setters and getter for all member variables.

This class has four different constructors:

1. A constructor with no argument.

2. A constructor with only one argument which is brand

3. A constructor with only two arguments which are brand and color

4. A constructor with only three argument which are brand, color and MPG.

If the caller of the constructor does not give a value for a particular member variable, a default

value should be assigned when a constructor is called:

The default value for brand is Ford.

The default value for color is Red.

The default value for MPG is 30.

This class (Car Class) has one public method named DisplayCarInformation(). When the method

is called, it prints the car’s brand, color, and MPG values.

In another class named CarTest, you will have a main() method. Within the main(), you need to

create at least 4 car instances. You must call the four different constructors in your program.

Since you have 4 or more Car objects, you MUST use ArrayList data structure to store them.

For each object, you need to call its DisplayCarInformation() method which will print the brand,

color, and MPG on the console and write to an actual file named carInfo.txt. Your output

format should be easy to understand.

Sample Output

“Ford, Red color, 30 mpg”

“Chevy, Red color, 30 mpg”

“Tesla, Green color, 30 mpg”

“Toyota, Blue color, 28 mpg”

Input

None

Output

Print cars’ information on console and to an actual file named carInfo.txt

SOURCE CODE:

package sampleproject;

public class Car {
private String brand="Ford";
private String color="Red";
private int MPG=30;
  
   public Car() {
       super();
   }
  

   public Car(String brand) {
       super();
       this.brand = brand;
   }
  
  

   public Car(String brand, String color) {
       super();
       this.brand = brand;
       this.color = color;
   }

  
   public Car(String brand, String color, int MPG) {
       super();
       this.brand = brand;
       this.color = color;
       this.MPG = MPG;
   }

   public String getBrand() {
       return brand;
   }

   public void setBrand(String brand) {
       this.brand = brand;
   }

   public String getColor() {
       return color;
   }

   public void setColor(String color) {
       this.color = color;
   }

   public int getMPG() {
       return MPG;
   }

   public void setMPG(int MPG) {
       this.MPG = MPG;
   }
  
@Override
   public String toString() {
       return "Car [brand=" + brand + ", color=" + color + ", MPG=" + MPG + "]";
   }

void DisplayCarInformation()
{
   System.out.println(" " +brand+", "+color+"color , "+MPG+"mpg");
}
   public static void main(String[] args) {
       // TODO Auto-generated method stub
       Car c1=new Car();
       System.out.println(c1.toString());
       c1.DisplayCarInformation();
       Car c2=new Car("Chevy","Red", 30);
       Car c3=new Car("Tesla","Green", 30);
       Car c4=new Car("Toyota", "Blue", 28 );
       System.out.println(c1.toString());
       c1.DisplayCarInformation();
       System.out.println(c2.toString());
       c2.DisplayCarInformation();
       System.out.println(c3.toString());
       c3.DisplayCarInformation();
       System.out.println(c4.toString());
       c4.DisplayCarInformation();
  
   }

}
OUTPUT:

Car [brand=Ford, color=Red, MPG=30]
Ford, Redcolor , 30mpg
Car [brand=Ford, color=Red, MPG=30]
Ford, Redcolor , 30mpg
Car [brand=Chevy, color=Red, MPG=30]
Chevy, Redcolor , 30mpg
Car [brand=Tesla, color=Green, MPG=30]
Tesla, Greencolor , 30mpg
Car [brand=Toyota, color=Blue, MPG=28]
Toyota, Bluecolor , 28mpg
