Adding data to an array. Im a beginner, help me out!!1:D

[carlos123]

Ok i just want to thank you for checking this out and helping me out. This is the problem, well not really problem, but this is what i want to do.

I have a bunch of textfields, when the "save" button is pressed, all the information is added to a database which is a bunch of arrays. This is all i have on that.

 if (event.getSource() == Bok)
           {
           
            firststring = first.getText();
            laststring = last.getText();
             agestring = age.getText();
            streetstring = street.getText();
            citystring = city.getText();
            
           }

I want this information to go into these arrays.

String[] firsta = new String[30];
       String[] lasta = new String[30];
       String[] agea = new String[30] ;
       String[] citya = new String[30];
       String[] streeta = new String[30] ;

Would someone explain how that would be done, please include some code. Please dont just write what should happen, because i wont be able to put it together. Im not asking you to do my homework, but i just need a place to start. This is only the beginning of this program, and im already lost. It might be easier to use arraylists??? Im uncertain how to use those exactly. Thanks for your time.

[code=java]
String arr = new arr[2];
arr[0]="some_value ";
arr[1]="some_value ";
[/code]

If you want to learn Java here you better start taking the advice that's given to you. In your last problem you were taught about how arrays are so Fortranesque yet you keep using them.

IMHO there should be a 'Person' class with 'firstName', 'lastName', 'age' etc. members
and all the getXXX methods; setXXX methods are probably not necessary for all
members. I'd implement an 'equals()' and 'hashCode()' method for that class as
well so that it can safely be stored in a Set<Person> set that mimics a database.
Probably a 'toString()' method comes in handy as well.

Last but not least: I'd avoid arrays like the plague for purposes like these.

kind regards,

Jos

Im sorry, i dont really understand. Could i see some sample code on how that would work? Also, the save button, has to clear the textfields. Would there be an easier way of inputing the data?

[carlos123]

 if (event.getSource() == save)
           {
          while (i < 30; i++} //why doesnt this work?
           {
            firsta[i] = first.getText();
            lasta[i] = last.getText();
            agesa[i] = age.getText();
            streeta[i] = street.getText();
            citya[i] = city.getText();
        }
           }

Please don't keep starting multiple threads for the same problem.
It is against site rules and is therefore a punishable offence.
