Reading a text file and transferring values into array

Question

Hi,
I have a problem. So what I am trying to do is that, I read a text file and insert specific values from the text file into an array for future needs.
But I have to make sure that there is no duplicate entries. So thats what I have but, my method takes forever to finish...
here is my code:
String nomFichier = "Test_" + numTest + "_" + date + ".txt";
        String ligne = "";
        int z = 0;
        int j = 0;
        BufferedReader lecteurFichier = new BufferedReader(new FileReader(nomFichier));
        while ((ligne = lecteurFichier.readLine()) != null) {
            if (z > 3)
                String valeur = "";
                String dist = "";
                boolean unique = true;
                String [] chiffre = ligne.split(";");
                 if (intervalleAnalyser == 1)
                    valeur = chiffre[3];
                    dist = chiffre[4];
                if (intervalleAnalyser == 2)
                    valeur = chiffre[2];
                    dist = chiffre[4];
                if (intervalleAnalyser == 3)
                    valeur = chiffre[1];
                    dist = chiffre[4];
                if (z == 4) {
                    intervalleDiagramme[j] = valeur;
                    j++;
                if (z > 4) {
                    for (int i = 0; i < intervalleDiagramme.length; i++)
                         for (int x = 0; x < i; x++)
                             if(intervalleDiagramme[i] == intervalleDiagramme[x])
                                unique = false;
                    if (unique)
                        intervalleDiagramme[j] = valeur;
                    j++;
            z++;
        lecteurFichier.close(); // toujours fermer le fichier

Hi,
Thanks for your reply,
1) Yeah I have a method that asks the question and assigns it to a variable.
2) Well the z will stop once there is no lines to read no?
for the set.add(), I am not that familar...
I changed bit a code and I have this now:
if (z > 4) {
                    for (int i = 0; i < intervalleDiagramme.length; i++)
                        System.out.println(intervalleDiagramme);
if(intervalleDiagramme[i].equals(valeur))
System.out.println(intervalleDiagramme[i] + " " + valeur);
unique = false;
if (unique)
intervalleDiagramme[j] = valeur;
EDIT:
I figured a way to assign " " to all the values in my array. But I get this error:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 380
at TP3.lireFichier(TP3.java:305)
And my line 305 is: intervalleDiagramme[j] = valeur;
EDIT2:
So ok I found my mistake and corrected it. But I want to know is there a way of doing this without setting the size of the array? because sometimes there needs to be 21 values sometimes 19 and sometimes 20....
If I take out: = new String [21] out I get a NullPointer error...
