java reading from csv file and storing its information into ArrayList<class> -

i'm java newbie , need help

so here main method:

registrationmethods dmv = new registrationmethods(); arraylist<carowner> itstate = new arraylist<carowner>(); dmv.processtexttoarraylist(itstate); 

and have class called carowner , has getters , setters firstname, lastname, license, month, year instance variables.

and method header processtexttoarraylist method:

public void processtexttoarraylist(arraylist<carowner> inlist) throws ioexception 

this method supposed add new carowner objects inlist carowner collection passed in. each line of csv file, carowner object added inlist.

i have read csv file arraylist csv file contains like:

bunny bugs acb-123 5 2013  bunny honey def-456 9 2013  bunny lola ghi-789 3 2014 

how code using while loop?

edit:

my carowner class :

public class carowner extends citizen implements carownerinterface, serializable { private string license; private int month, year;  public carowner() {     super();     license = "not assigned";     month = 0;     year = 0;         }  public carowner(string infirst, string inlast, string inlicense, int inmonth, int inyear) {     super(infirst, inlast);     license = inlicense;     month = inmonth;     year = inyear; }  public void setlicense(string inlicense) {     license = inlicense; }  public string getlicense() {     return license; }  public void setmonth(int inmonth) {     month = inmonth; }  public int getmonth() {     return month; }  public void setyear(int inyear) {     year = inyear; }  public int getyear() {     return year; }  public int compareto(object o) {     if ((o != null ) && (o instanceof carowner))     {         carowner otherowner = (carowner) o;         if (otherowner.compareto(getyear()) > 0)             return -1;         else if (otherowner.compareto(getyear()) < 0)             return 1;         else if (otherowner.equals(getyear()))             if (otherowner.compareto(getmonth()) > 0)                 return -1;             else if (otherowner.compareto(getmonth()) < 0)                 return 1;             else if (otherowner.equals(getmonth()))                 return 0;     }     return -1; } 

}

and citizen class also:

public class citizen implements citizeninterface, serializable { private string firstname, lastname;  public citizen() {     firstname = "no name";     lastname = "no name"; }  public citizen(string infirstname, string inlastname) {     firstname = infirstname;     lastname = inlastname; }  public void setfirstname(string infirst) {     firstname = infirst; }  public string getfirstname() {     return firstname; }  public void setlastname(string inlast) {     lastname = inlast; }  public string getlastname() {     return lastname; }  public string tostring() {     string str;      str = firstname + " " + lastname;      return str; } 

you use method , provide path file wish read from. creates scanner read file passed in.

it grabs each line 1 @ time , adds new carowner(string,string,string,string,string) object result array.

p.s. have no idea implementation of carowner used strings... i'll leave figure out heh.

public arraylist < carowner > processtexttocarownerlist(string filepath) throws ioexception {     arraylist < carowner > result = new arraylist < carowner > ();     scanner scan = new scanner(new file(filepath));     while (scan.hasnextline()) {         string line = scan.nextline();         string[] linearray = line.split(" ");         result.add(new carowner(linearray[0], linearray[1], linearray[2], linearray[3], linearray[4]));         }         return result;     }
