am trying to populate a JComboBox named choices from an external file. I have the import/read portion working because if I add System.out.println(name[ i ]); to the code it will print the contents of the file on the screen. Is the code below correct to populate the box? I get an error code of "cannot find symbol" with eiter get or setText.

CODE

choices.getText(loan [ i ]);

If you've got an existing JComboBox and you want to set its list of items to the contents of a String array, you could do this:

combo.setModel(new DefaultComboBoxModel(names));

or if you have the "names" array around when you first create the combo box, you can just say

combo = new JComboBox(names);

download a copy of the api docs, and you'll find (in JComboBox)

a method
public void addItem(Object anObject)

a constructor with an array as a parameter
public JComboBox(Object[] items)
"Creates a JComboBox that contains the elements in the specified array.
By default the first item in the array (and therefore the data model)
becomes selected. "

ok I am still lost here can someone edit this example from Sun to give me a better idea of what I am doing wrong? I can make it pull the data but not fill a combobox.

I'm not sure what you're trying to do.

You have an editable comboBox, so I'm guessing you want the edited, or new,
value to be added to the drop-down list (when [enter] is hit)

if so, add this if statement to actionPerformed()
