Hello guys well I have been working in this arraylist that is now driving me crazy!
Bascially I wrote a CAR class which has some methods in it, however now I created an arraylist so it could store cars from the other class and at the same time have access to some of the methods of that class such as rentTheCar or returnCar. I am having trouble with three things.
First showCar is just now working properly it shows me all the cars although I put the carNumber when I invoke the method, moreover I want the method to print the description of that particular car.
The rentTheCar method is renting the car, well Basically renting all the cars at the same time instead of renting the car with carNumber specified when invoking the method.
The return car method does exactly the exact same as the rentTheCar method but in this case it returns them all insetad of just returning the car specified when invoking the method.
Here I leave both classes:
public class Car
{
// This represents the car's features entered by the user.
private String description;
// This represents the name of the user or the person that will rent the car.
private String name;
// This represents the days that the car will be rented for.
private int days;
// This represents the down payment made bny the user to rent the car.
private int deposit;
// This represents the daily rate of rental for the car.
private int rate;
// This represents the start date of the rental.
private String dateOfHire;
// This represents the date that the car will be returned.
private String dateOfReturn;
// This represents the total amount of money that will be paid until the end of the rental.
private int totalRent;
// This represents the status of the car, that can be rented or not rented.
private boolean onLoan;
/**
* Stablish a car with first features such as description and rate.
*/
public Car(String carDescription, int dailyRate, int downPayment)
{
description = carDescription;
rate = dailyRate;
days = 0;
name = "";
dateOfHire = "";
dateOfReturn = "";
deposit = downPayment;
totalRent = 0;
onLoan = false;
}
/**

*/
public String getDescription()
{
return description;
}
/**

public void displayDescription()
{
System.out.println(" Rental Review ");

}

}and now the Rental arraylist
