[horace1]

you have a ; on the of the line

  public void actionPerformed(ActionEvent e);
 

which makes the compiler think there is no code for the method

[cazconv2007]

i've changed that but still have an error it says that my face class is not abstract

[horace1]

i've changed that but still have an error it says that my face class is not abstract

if I remove the ; and recompile the message about the abstract class goes away and I get a few more messages starting with

Face.java:42: cannot find symbol
symbol  : variable SMILE
location: class Face
                        SMILE = true;
