 			JOptionPane.showMessageDialog(null, comedy[i].toString());
           }

I assume you have problems with this bit :

class MenuListener implements ActionListener{
   public void actionPerformed (ActionEvent e){
     if(e.getSource() == displaySchedule){
      Database.viewAll();
     }
     else if(e.getSource() == displayAll){
       textField.setText("Open an existing file");
     }

you call 'Database.viewAll();' which is a call to a static method in the Database class. However there is no such method.

I think you wanted to do 'database.viewAll();' to invoke the viewAll method on the instance of the Database class you created in the main method.

However, you would also have to change the database variable to an instance variable by moving the declaration (or definition, i can never remeber) out of the main method as it's scope is now limited to the main method.

Hope this helps,
