EditableJComboBox

Question

I'm using an editable combobox with about 8000 items.
Then it's quite difficult to select the disired item in the list. I'd like the combo box to follow me while typing:
i.e. if i type "M", I want the combobox to display the first item starting wiyh M, but if i type "MI", I want the combo box to display the first item starting with MI and so on.
Is it possible with an editable combobox or should I change component?
Please help me, I'm really in trouble!
Thank you in advance.

if you add a keyListener to the ComboBox and then use that to go to the letter pressed then you can do it like this:    BuySellComboBox.addKeyListener(new java.awt.event.KeyAdapter() {
      public void keyReleased(KeyEvent e) {
        BuySellComboBox_keyPressed(e);
  void BuySellComboBox_keyPressed(KeyEvent e) {
    char typed = e.getKeyChar();
    switch (typed) {
      case ('b'):
     BuySellComboBox.setSelectedIndex(1);
     break;
      case ('s'):
     BuySellComboBox.setSelectedIndex(2);
     break;
      default:
     BuySellComboBox.setSelectedIndex(0);
  }As you can see my combo box only has buy or sell as it's options though, if you want to search on more letters then just add the char from the key pressed to a string and then write a for for loop that searches the ComboBox until it finds :those letters:
int row=0;
String myLetters="mi";
for (int x=0;x<ComboBox.getMaximumRowCount();x++){
   if (ComboBox.getSelectedItem().toString().subString(0,myLetters.length()).equalsIgnoreCase(myLetters)) {
      row=x;
      break;
ComboBox.setSelectedIndex(row);However what if the person types some letters, then changes their mind and types a different letter?
Hope you can do something with this.
If not you may want to use a JList.
