Working with JTextArea and things like that

Question

I don't know if this is the right subforum for this.. if not, feel free to move it over to another subforum
Now i have this exercise.
I made a file for it , a list.data file. If i run the program, it gives the info in the list.data file in a whole new box.
So this is in the data file for example:
Toyota
Hilux
Volkswagen
Rabbit
Jeep
Wrangler
Than if i run the program, it opens a new window and then there is in it:
Toyota
Hilux
Volkswagen
Rabbit
Jeep
Wrangler
Now the assingment is to create a new car class with the relevant instance variables (just to store the property values i assume). And thereby i have to create relevant methods to access the instance variables. I also have to create a constructor that accepts initial values for the car instance variables.
The given program is working with two classes. Those are given, i don't need to understand their internal details, says the exercise
This is a whole new part of Java for me. Can someone give me an example or a hint or something like that?
Can i just make a new class with in it the car information
so like:
import java.util.*;
public class CarInformation {
    String[] brand = new String[5];
    String[] type  = new String[5];
    public void brands(){
        brand[0]   = "Toyota";
        brand[1]   = "Volkswagen";
        brand[2]   = "Jeep";
    public void types(){
        type[0]    = "Hilux";
        type[1]    = "Rabbit";
        type[2]    = "Wrangler";
    public CarInformation() {
}If this is right, how can i make the bigger program to read from my new CarInformation class? I think i'm in the dark..

Hmm, it is not my intention to get on your nerves..You aren't! Sorry if my post sounded that way.
My comments are inline:
import java.util.*;
public class Car{
    String Brand;
    String Type;
    String Car;    // this isn't needed. the brand and type are the only attributes of a car you need, right?
// setting the initial values of brand and type is done by the constructor, you don't need these
//    public void Brands(){
//        //reserved to store intital markings for Brand variable
//    public void Types(){
//        //reserved to store intital markings for Type variable
    // constructors have to have the same name as the class, not CarBrand, or CarType
/*    public void CarBrand(String Brand) {
        this.Brand = Brand;
// this is right
    public String getBrand() {
        return Brand;
/*    public void CarType(String Type) {
        this.Type  = Type;
// this is right
    public String getType() {
        return Type;
    // change this method name to Car so that it's a constructor. once that's done, it's correct
    public void CarSpecs(String Brand, String Type){  //this one if we can get both Brand and Type in with one method?
        this.Brand = Brand;
        this.Type  = Type;
// this works too, but you'll want to add a space between the brand and type
        public String getCarSpecs() {
        return Brand + Type;
    public static void main(String[] args) {
//        new Car().getCarSpecs();
          Car someCar = new Car("honda", "civic");    // create a new car with "honda" and "civic" as the brand and type
          String theSpecs = someCar.getCarSpecs();    // get the specs String from that car
          System.out.println(theSpecs);     // print those specs
}
