Error with displaying int textArea

[Johanis]

reads from the database:

public DierObj[] result ()
      {
      DierObj[] arr = new DierObj[60];
      
         try
         {
            Statement stmt = dbcon.createStatement ();
            String sql = "SELECT * FROM Diere";
            ResultSet rs = stmt.executeQuery (sql);
            int tel = 0;
            while (rs.next ())
            {
               arr[tel] = new DierObj();
               arr[tel].setId(rs.getInt ("ID"));
               arr[tel].setWetnam(rs.getString ("Scientific Name"));
               arr[tel].setNaam(rs.getString ("Naam"));
               arr[tel].setBeskrywing(rs.getString ("Beskrywing"));
               tel++;
            } // while

         }

My Object class with getters and setters:

class DierObj {

    private int Id;
    private String Wetnam;
    private String naam;
    private String Beskrywing;

    public DierObj(int Id, String Wetnam, String naam, String Beskrywing) {
        this.Id = Id;
        this.Wetnam = Wetnam;
        this.naam = naam;
        this.Beskrywing = Beskrywing;
    }

    public DierObj() {
        this.Id = 0;
        this.Wetnam = "";
        this.naam = "";
        this.Beskrywing = "";
    }

Class where i display the information read:

public class Dier extends javax.swing.JFrame {
    Connect dierinfo = new Connect();
      String[] gSkik;
        DierObj[] data;
        String koos;
    /** Creates new form Dier */
    public Dier() {
        data = dierinfo.result();
        this.setVisible(true);
        initComponents();
    }

the line with the error:

textArea1 = new java.awt.TextArea(data.getNaam());

Error:
C:\Users\Johannes\Documents\IT\2012\PAT 2012\Fase 3\Wildresjava\src\Dier.java:40: cannot find symbol
symbol : method getNaam()
location: class DierObj[]
textArea1 = new java.awt.TextArea(data.getNaam());
1 error

I cannot understand why it can't find the method getNaam. At School it was working.

1. data isn't a DierObj. Look at line 4 in the third code segment you posted. What is the type of data?

2. (but more important) Follow the Java coding conventions. Variable names should not start with an uppercase letter.

Ill be sure to read through the coding convention thanks.

I don't understand what you mean. According to what I know the types are correct?

Those little square brackets are significant, e.g. a DierObj isn't a DierObj[].

Its suppose to be [] because I'm working with a array?
Ive tried everything, can't seem to figure it out and my project's deadline is due for two days.

[Johanis]

Please help! I'm wasting so much time on this.

[JosAH]

'data' is an array of DierObj but you're treating it as if it were a single DierObj; the compiler doesn't buy that.

I'm first trying to display only the first thing read out. I'm so completely confused, because at school it worked. I don't know how to fix the problem you confronted me with...

[Johanis]

I got it working!

public class Dier extends javax.swing.JFrame {
    Connect dierinfo = new Connect();
    String[] gSkik;
    DierObj[] data;
    int tel = 0;
   /** Creates new form Dier */
    public Dier() {
        data = dierinfo.result();
        this.setVisible(true);
        initComponents();
    
    }

textArea1 = new java.awt.TextArea(data[tel].getNaam());

[JosAH]

If you have put the 'first thing read' in the array, data[0] might be what you're looking for; if it worked at school you must've ran different code there. b.t.w. I didn't confront you with anything; your compiler did that (and rightly so).

kind regards,

Jos

[Johanis]

I'm actually Afrikaans, not that great in English, the confront part was meant like the problem that you are talking about.

Can you speak Zuid Afrikaans or even Dutch?

kind regards,

Jos

[Johanis]

I can speak Suid-Afrikaans and understand a little Duch.

This is so cool; let's do the secret dance and the secret handshake (zodat andere mensen er helemaal niets van begrijpen ;-)

kind regards,

[Johanis]

Hahahaha omw! Ek sou nooit dink daars iemand hier wat Nederlands praat nie. =D

[JosAH]

Hahahaha omw! Ek sou nooit dink daars iemand hier wat Nederlands praat nie. =D

I understood that; Zuid Afrikaans (Suid Afrikaans) must sound and look like some medieval form of Dutch (they were both the same in those days); fascinating ...

vriendelijke groet,

Jos

[Johanis]

Yeah, its thanks to Duch that we have Afrikaans.
Vriendelike groete

Yep, us Dutch have always been good, altuistic, fine benevolent people; while other tribes went to war, us Dutch gave away our beautiful language for free ;-)

Tell them to behave for once ... the Dutch are everywhere around the globe as in 'scum floats' ;-)

ps. thanks for the nice words; I'll tell my fellow Dutchmen around here about you, so be warned ;-)
