Function problem....=0 *Resolved by CornedBee*

I'm sure the what I screwed up was simple but for the life of me I can't figure out what it is. This function ALWAYS returns the string letter F.

VB Code:

public static String ProcessLogin(Vector UL, String Data, int Logging)
    {
        String sReturn = "";
        String[] sSplit = new String[4];
        int i = 0;
        String sTemp = "";
        
        sSplit = SplitSaP(Data);
        
        for(i = 0; i < UL.size(); i++)
        {
            if(sSplit[1] != ((UserList)UL.elementAt(i)).sUsername)
            {
                sReturn = "F";
            }
            else
            {
                sReturn = "S";
                i = UL.size() + 1;
                System.out.println("Raaar");
                break;
            }
            
            if(Logging == 10)
            {
                System.out.println(((UserList)UL.elementAt(i)).sUsername +"=?"+ sSplit[1]);
                System.out.println(sSplit[2] +"=?"+ ((UserList)UL.elementAt(i)).sPassword);
                System.out.println(sReturn);
            }
        }
        return sReturn;   
    }

First, some inefficiencies. You only need to initialize sReturn, and you don't need sTemp at all.

Second, you need to use String.equals to compare strings.

Here's a revised function, complete with naming convention changes (I always use the Java convention for Java code, I hate it when I have a different naming convention than the libaries I use)

Code:

---

public static String processLogin(Vector ul, String data, int logging) {
  String ret = "";
  String[] split;
  int i;

  split = splitSaP(data);

  for(i = 0; i < ul.size(); ++i) {
    if(!(split[1].equals(
        (UserList)UL.elementAt(i)).username)) {
      ret = "F";
    } else {
      ret = "S";
      System.out.println("Raaar");
      break;
    }

    if(logging == 10) {
      System.out.println(
        ((UserList)ul.elementAt(i)).username +"=?"+ split[1]);
      System.out.println(
        split[2] +"=?"+ ((UserList)ul.elementAt(i)).password);
      System.out.println(ret);
    }
  }
  return ret; 
}

Besides, I think you should be returning a boolean, not a string.

I end up having to return a String later because I will be adding other information in there which needs to be checked but ya its pretty inefficent. And I just tested replacing that with string.equalsIgnoreCase(string) and it always returns F again. But for whatever reason your function works and mine didn't when I just changed that so *shrugs* Thanks. The reason I do that is I use the same naming convention for ALL of code, no matter what language I use. And since I don't distribute my source it does make life easier for me and doesn't affect anyone else.
