Answer 1

You could make your JComboBox a class member variable & add a method to return result of getSelectedItem:

public class MyGuiApp {

    private JComboBox comboBox;

    // constructor, init method, etc.

    public String getSelectedItem() {
       return (String)comboBox.getSelectedItem();
    }
}
