Inserting Records in an Array and using a constructor with it

Question

I badly need help on this! Please please please! I have been studying java for a short time only.
Anyway, here goes: My project requires the following:
Employee inputs the no. of video in the shelf. They have four classifications: Drama, Comedy, Action, and Thriller. Each video classification has different rates. The employee creates a video record containing the following information: 1. video ID number, 2. video classification, and 3. Price.
The employee should display the classifications of videos available and the price. Only the available video tapes would be displayed according to the customer's chosen classification. When the customer chooses the video he wants to rent, the program will register and attach the name of the customer to the video number.
I only need to use arrays, and NOT database to record the information.

Answer 1

is it ok i i declare the drama_rate outside the video class?
i have a list of variables on my videoupdate classYes. It's probably best to declare it static & then you can access it directly:
public static float drama_rate = 100.0;
rate = <the class name>.drama_rate;
so, i should also include a customer no. both in the video and customer class.I would. You may want to list a bunch of videos and who currently has them. This way you don't have to search the customers AND the videos to do this.
thanks =) i don't know either why we had to validate/invalidate,\
but our applet doesnt refresh when >it is supposed to, so
we just used this method. It wouldnt slow down the application, would it?Could you just revalidate()?
the use of arrays. i havent finished with the program yet.
i have the design already, i just couldnt put it in code.
im not familiar with the use of multidimensional arrays-
can i use this for the video and customer records i will need to store?Not sure what you're using arrays for, but here's an example of something I might do. Maybe it will be useful to you.
Have you looked at HashMaps? You could use "Customer" as the key and then use an ArrayList of checked out Videos as the value:
HashMap customers = new HashMap();
ArrayList videos = new ArrayList();
//Add the checked out videos to the list
videos.add(video);
<etc>
// Add this customer and the list of videos he has checked out.
customers.put(customer,videos);
