some conditions. this is a single lane car garage that fits up to 10 cars.
when cars try to arrival when its full it gets turn away. if a car try to leave
and its not in the garage, it cant be found. when its the car turn to depart from
the garage needs to produces how many times it was moved while it was still in the garage.
i just need to work on the void printL() to produce those statements. thanks for anyhelp.

Explanation / Answer

You very well could perform all the logic within the printL method. However, that'd defeat the purpose of the design. I suggest to create an arrive and depart method on the garage class or to do more processing in the addC method. You want to use the list to model the parking spaces with it's finite space and it's ordering. You'll want add to the end of the list for arrivals if and only if the size of the list is 10 or less. Otherwise, you'll want to turn the car away. For departures, you'll want to find the car in the list by license. You'll want to remove it from the list (if present) and increment the move count of all car objects ahead of it in the list. When you report the departure of a car, report the car's move count. If you do this, you can put the print statements in the arrive/depart or addC method and you might not need a print method at all. Beware that the ArrayList will expand to fit whatever size necessary. Initializing it to 10 will not cause it to prevent 11 or more entries in the list. Refactor the Garage class and perhaps the tester class, and repost if you get stuck.
