    text
    copied!<p>Well basically I have an assignment that has to be done for January. I have to to create a mock rental service that allow customers to rent cars. I am basing the logic off of an ArrayList, using its methods to manage my car collection.</p> <p>I have some problems with my code, the logic in a lot of my methods is not working correctly. In the code sample I included the <code>showCar</code>, <code>rentTheCar</code> and <code>returnCar</code> methods are not working as they should. The <code>showCar</code> method displays all the cars, although when invoking the method it asks me for the <code>carNumber</code>. The <code>rentThecar</code> and <code>returnCar</code> seem to be renting/returning all cars, instead of just the one I specify.</p> <p>I am showing relevant code from my classes below, if anyone can help me figure out where I might have gone wrong.Please I want to make it clear that i do not want my homework done just some guidance. Thanks.</p> <p>Show car method:</p> <pre><code>public void showCar (int carNumber) { if (cars.size() &lt; 0 ) { System.out.println ("Add cars first!!!"); } else if (carNumber &lt; cars.size()) { System.out.println(cars.get(carNumber)); } else{ System.out.println("Error!! This note cannot be shown, because it does not exist!!"); } } </code></pre> <p>Rent car method:</p> <pre><code>public void rentTheCar (int carNumber, String CustomerName, String hireDate, String returnDate, int daysOfHire) { if (cars.size() &lt; 0) { System.out.println("Empty list!! Add cars first!!"); } else if (carNumber &gt; cars.size()) { System.out.println("This car does not exist!!"); } else { for (Car car : cars) { int index = 0; cars.get (carNumber); car.rentTheCar(CustomerName, hireDate, returnDate, daysOfHire); index ++; } } } </code></pre> <p>Return car method:</p> <pre><code>public void returnCar (int carNumber) { cars.get(carNumber); if (cars.size() &lt; 0) { System.out.println("Error!! It is impossible to return a car from an empty list"); } else if (carNumber &gt; cars.size()) { System.out.println("Error!! Not a valis car!!"); } else { for (Car car : cars) { car.returnTheCar(); System.out.println ("The car has been returned correctly"); } } } </code></pre>
