how do I limit the number of characters that the user can enter in jcombo box.

You can add a DocumentFilter to the editor of the combo box:

ComboBoxEditor editor = comboBox.getEditor();
JTextField textField = (JTextField)editor.getEditorComponent();
AbstractDocument doc = (AbstractDocument)textField.getDocument();
doc.setDocumentFilter( ...);

Read the section from the Swing tutorial on Implementing a DocumentFilter for an example filter the limits the number of characters that can be entered.
