How could this be achieved

Question

Hey everyone,
I have information stored in side a file, it is first stored in arrays like this:
String[] cars = {"ford", "ford", "mini"}
int[] car_id = {101, 102, 103}
It is then written to a file.
I would like to make a record or my own type of some sort, that would combine these into one record like this. So the record would read this:
record 1: ford, 101
record 2: ford, 102
record 3: mini, 103
This would be easy to change the values as well, as i could just say record1 = "ford", "201" or something.
Any suggestions on how this could be achieved.

Thanks for those great links!
I've now read up about constructors and classess again, so i'm a little more confident. I am having a little trouble printing and retreiving the information in the objects. Here is some of my code:
class Details{ //storage for cars and details
        public int customer_id; //id of customer hiring it
        public String type; //small, saloon or van
        public int rate; //rate of hire
        public int mileage;
        public boolean hired; //hired or not
        // constructor
        public Details(int id, String t, int r, int m, boolean h) {
                set_customer_id(id);
                set_car_type(t);
                set_rate(r);
                set_mileage(m);
                set_hired(h);
        // return object variables
        public int get_customer_id() { return customer_id; }
        public String get_car_type() { return type; }
        public int get_rate() { return rate; }
        public int get_mileage() { return mileage; }
        public boolean get_hired() { return hired; }
        // set object variables
        public void set_customer_id(int id) { customer_id = id; }
        public void set_car_type(String car_type) { type = car_type; }
        public void set_rate(int the_rate) { rate = the_rate; }
        public void set_mileage(int miles) { mileage = miles; }
        public void set_hired(boolean car_hired) { hired = car_hired; }
class Cars {
        public static void main(String[] args) throws IOException {
             Details[] thecars = new Details[] {new Details(1, "small car", 20, 0, true), new Details(2, "big car", 220, 3, true)};
}I'm really unsure how i could retrieve the details. I though tthis would work:
String type = thecars[0].get_car_type;
Because thecars is an array of Details[] and get_car_type returns the type of car. Any suggestions?:
Thanks.
