                public void actionPerformed(ActionEvent e) 
                {
                    Color orginalColor = mcoef.getBackground();
                    switch(countresultsfrom.getSelectedIndex())
                    {
                        case 0: // Mech Cnt;
                            mtotal.setBackground(Color.YELLOW); 

                            if(mstatus.getSelectedIndex() == 2)
                            {
                                countresultsfrom.setSelectedIndex(2);
                                // countresultsfrom <----- CALL EVENT ???
                            }

                            ctotal.setBackground(orginalColor);
                        break;
                        case 1: // El Cnt;

your descriptions isn't clear for me, but there is basicall two ways

1/ create own Class someName implements ActionListener

2/ create java.swing.Action some examples for that on Action

EDIT:

if your countresultsfrom is JList, then all ours advices (maybe) didn't correct at all http://download.oracle.com/javase/tutorial/uiswing/components/list.html

First of all extract your action performed method to a separate class in your code. It could be a private static class in the same class you wish to call. e.g

private static class ColorActionHandler implements ActionListener {
   //implement your method here by looping twice. or create a method for your logic and then call it in a for loop in the actionPerformed method
}

and pass an instance of this class in the addActionListener of your countresultsfrom button.

  1. You could simply call yourListener.actionPerformed(/*some event*/ e). Note that it will not be handled as an event, but as a regular method call.
  2. #1 is the simple technical way. It is not recommended. If you want some logic to occur, wrap it in a method and call that method, ActionListeners are meant for handling GUI events.

Do you wish actionPerformed(ActionEvent e) to be invoked twice on every action?

If so, wrap the block starting with Color orginalColor = mcoef.getBackground() in a for-loop. for (int i=0; i<2; i++) { ... }
