Dynamically change JComboBox

Question

I am fetching the data values from the database successfully. I have also stored them into a String[] array. I need to load the String array as the items of the JComboBox in response to key actionperformed. How can I reload the items of the JComboBox whenever a key is pressed as the fetched values depend on the key pressed. Rather simply, I need to dynamically refresh the JComboBox items.

Answer 1

DefaultComboBoxModel<String> model = new DefaultComboBoxModel<>( yourStringArray ); comboBox.setModel( model ); 

Answer 2

You have a couple of options. You can use removeAllItems() (or one of the other remove methods) and addItem(Object anObject) to manipulate the selectable objects. Or you could implement a ComboBoxModeland allow it to serve up data from your array.
