How do I detect that a JComboBox is empty?

Question

How do I detect that a JComboBox is empty? Is it something like:

combobox.isEmpty()

Answer 1

What's wrong with JComboBox.getItemCount()? If this method returns 0, the component is empty.

Answer 2

if(JComboBox.getItemCount() != 0){
  //JComboBox is not empty - do something..  
}

Answer 3

I suppose you're looking for getItemCount() method
