Populate JCombo from Database

Question

I have a code that populates Combo box from a db and its ok. however, the items are displayed enclosed in brackets i.e. instead of seeing
Coptic Hospital
i see
[Coptic Hospital]
i dont want to see the brackets. here's the code
    public void getSp(){
    String query="SELECT Provider FROM `smartmain`.`providers` p ";
    JDataBase db=new JDataBase();
    providers=db.getData(query);
    for(int i=0;i<providers.size();i++){
     ComboSp.addItem(providers.elementAt(i));
    }getData is a function in JDataBase class.
       public Vector getData(String query) {
         int no_rows=0;
         if (connection == null || statement == null) {
           System.err.println("There is no database to execute the query.");
           return new Vector();
       try {
           resultSet = statement.executeQuery(query);
           metaData = resultSet.getMetaData();
           int numberOfColumns =  metaData.getColumnCount();
           columnNames = new String[numberOfColumns];
          // Get the column names and cache them.
           // Then we can close the connection.
           for(int column = 0; column < numberOfColumns; column++) {
               columnNames[column] = metaData.getColumnLabel(column+1);
           // Get all rows.
           rows = new Vector();
           while (resultSet.next()) {
                no_rows++;
               Vector newRow = new Vector();
               for (int i = 1; i <= numberOfColumns; i++) {
                   newRow.addElement(resultSet.getObject(i));
               rows.addElement(newRow);
       catch (SQLException ex) {
           System.out.println(query);
           System.err.println(ex);
       return rows;
   }how should i remove them?

Answer 1

Your getData() function is returning a Vector of Vectors, so you are adding a Vector to your combo box model. A Vector's toString() method will return its contents in [] brackets.
