如何从数组中为 Jtextfield 设置文本？

Question

I have a problem when doing my project. I connect my database and get database about the value of food. I put all of the value to the array (public static array). But I wondering that anyway can I set the text of the textfield by the value from the array? Here is my declaring array:

public static String[] fp;

----------- main()

fp = new String[9];
            try {
                ResultSet rs = st.executeQuery(get_food_price);
                int i =0;
                while (rs.next()) {
                    System.out.println(rs.getString(1));
                    fp[i] = rs.getString(1);
                }
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

----------- private void initialize() {

food1_price.setText(fp[1]);

------------ It's not working with fp[1] (array) but It do work with normal string like "acb" or "asdsa"

Can you try this?

    MySQLConnection db = new MySQLConnection();
    Connection connect = db.getmysql_connection();
    String query="SELECT * FROM "; //Your query
    Statement stmt = (Statement) connect.createStatement();
    ResultSet rs = stmt.executeQuery(query);
    int i=0;
    while (rs.next()) {
        System.out.println(rs.getString(1));
        fp[i] = rs.getString(1);
        i++;
    }
