Tryin to sort a search method for abit of code. Have an array list reading from a csv. Any help on how I can get a search method searching through and displaying onto a jTextArea? This is my code in my Gui

public class DataGUI extends javax.swing.JFrame {

public class DataGUI extends javax.swing.JFrame {

    /**
     * Creates new form DataGUI
     */
    ArrayList<Bmx> people;
    public int count = 0;
    DefaultTableModel tableModel = new DefaultTableModel(
            new Object[][]{}, new String[]{
        "Rank", "First Name", "Last Name", "Uni Code", "Country", "Time"
    });

    public DataGUI(ArrayList<Bmx> people) {
        initComponents();
        this.people = people;
        drawTable();
        jTable1.setModel(tableModel);
        jTable1.setAutoCreateRowSorter(true);


    }

    public void drawTable() {
        tableModel.setRowCount(0);
        for (int i = 0; i < people.size(); i++) {
            Object[] object = new Object[9];
            object[0] = people.get(i).getRank();
            object[1] = people.get(i).getFirstName();
            object[2] = people.get(i).getLastName();
            object[3] = people.get(i).getUciCode();
            object[4] = people.get(i).getCountry();
            object[5] = people.get(i).getTime();
            tableModel.addRow(object);

        }
    }

    public void dataShow() {

        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());

        count++;
    }

    public void dataMinus() {
        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());

        count--;
    }

    private void search() {
        String Name = jTextArea1.getText();
        String record = "";
        int count = 0;

        for (int i = 0; i < people.size(); i++) {
            String name = people.get(i).getFirstName();

            String[] splitName = name.split(" ");

            if (Name.equals(splitName[0]) || Name.equals(splitName[1])) {
                count++;
                record = record + "\n" + people.get(i).toString();

            }
            jTextArea1.setText("");
            jTextArea1.append(count + " result(s) found for " + Name);
            jTextArea1.append("\n " + record);
        }
    }

what exactly is it supposed to do, and where are you stuck? you're not giving us much information to go on here...

I have a gui and I need to create a search method that can search through the data that I have in the csv file

yes, you have a GUI.. uhm .. it has to "search" .. based on what?

according to these two methods:

public void dataShow() {
        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());
        count++;
    }
    public void dataMinus() {
        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());
        count--;
    }

my guess is, you have 'columns' for rank, firstname, lastname, ucicode, country and time.
am I right in thinking you 'll enter one value and be searching based on that?

also: avoid having repeating code. the above methods can be simplified in two ways (that are very easy to implement), yet make your code a lot easier to read.

    public void dataShow() {
        setTexts();
        count++;
    }
    public void dataMinus() {
        setTexts();
        count--;
    }

    private void setTexts(){
        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());
    }

or:

public void setTexts(boolean add){
        jTextField1.setText("" + people.get(count).getRank());
        jTextField2.setText("" + people.get(count).getFirstName());
        jTextField3.setText("" + people.get(count).getLastName());
        jTextField5.setText("" + people.get(count).getUciCode());
        jTextField4.setText("" + people.get(count).getCountry());
        jTextField6.setText("" + people.get(count).getTime());
        if ( add )
            count++;
        else
            count--;
    }

read the contents of the file into a List or Set, and search through that, it'll take less time then each time reading through the file.

Yeah okay thanks. I just don't understand how to get it all into a button click and then displaying into a Jtextarea or something like that. I'm finding it difficult to bring it in from the array?

how to get all what in a button click? it's just writing the code in another location, you don't have to change anything to the code.

I want to have a button called 'search' and type someones name in and click and search for them. Then displaying the names in a text area. This is my data that im reading in.

well, you can (for instance) create a class "Entry" which keeps all that information.

List<Entry> myEntries = readFromFile();

// on clicking:
String searchName = jTextField1.getText();
List<Entry> found = new ArrayList<Entry>();
for ( Entry test : myEntries ){
  if ( test.getName().equals(searchName))
    found.add(test);
}

or, you could use the contains instead of the equals method, depending on your needs.

This is a good Java solution
