question regarding looping

[Eric Sexton]

I have that looks like this:

 
String ssn = ((PersonForm)passedForm).getSsn();
 

In my servlet, there is an attribute that I can check to see how many SSNs are submitted in the form. What I want to do is build som type of looping logic to cycle through these. In other words I want this effect:

  
String ssn1 = ((PersonForm)passedForm).getSsn1();
String ssn2 = ((PersonForm)passedForm).getSsn2();
String ssn3 = ((PersonForm)passedForm).getSsn3();

So I want to avoid typing out each of the preceding lines because I can potentially have 30 SSNs submitted on the form. What's the cleanest way to do this?

Try this:

class PersonForm {
    ....
    public String[] getAllSsn() {
        ....
    }
    ....
}
class yourServlet extends HttpServlet {
    ....
    String[] ssn = ((PersonForm)passedForm).getAllSsn();
    for(int i=0; i < ssn.length; i++) {
        //Do whatever with each ssn[i]
    }
    ....
}

Each of those getSsnX methods actually correspond to a form bean in Jakarta Struts. So this dynamic form could potentially have 30 text boxes on a screen that each have an Ssn in them. Not all the fields are required either. So even though 30 Ssns may be on the form, the user can choose to simply enter in 1 Ssn.

public String[] getAllSsn() in PersonForm could just call each of the getSsnx methods and return an array of all the Ssn's that were actually entered.

Take a look at how to use Indexed Properties in the Struts documentation. You can use arrays or Lists to represent groups of data rather than having 30 member variables and 60 accessor methods.
