java - The two Strings don't update, keep returning "?" -

this class file of whole project. i've checked everyother class , found culprit. it's supposed take in city , state parsed in class(so you're left city=dallas , state=tx example) when parameter passed through, don't update private string state , private string city.

i keep getting ?,? output tostring method

    public class address  { private string city; private string state;  public address()     {     city="?";     state="?";     }  public string getcity()     {     return city;     }  public string getstate()     {     return state;     }  public void setstate(string s)     {     //system.out.println(s);     state=s;     //system.out.println(state);     }  public void setcity(string c)     {     city=c;     }  public string tostring()     {     string citystate=city+","+state;     return citystate;     }  }

bankparser.java class

    public class bankparser      { public static bank bankparser(string linetoparse) {     bank bank=new bank();     string delims="[/]+";     string[] primaryparse=linetoparse.split(delims);     bank.setbankname(primaryparse[0]);     bank.setbankid(primaryparse[1]);     string[] secondaryparse=primaryparse[2].split("[,]");     //string city=secondaryparse[0];     //string state=secondaryparse[1];     bank.setbankaddress(secondaryparse[0], secondaryparse[1]);     //system.out.println(secondaryparse[1]);     return bank; }       }   

public void setbankaddress(string city, string state) {     address.setcity(city);     address.setstate(state); } 

here problem, did want do

public void setbankaddress(string city, string state) {     bankaddress.setcity(city);     bankaddress.setstate(state); } 

instead.
