See the two comments in this next code block.

    // The enclosing class does not implement the ActionListener
    // interface so this method will not be called.
    public void actionPerformed( ActionEvent e )
    {

        int guess;
        guess = Integer.parseInt(guessInputJTextField.getText());
        number = Integer.parseInt((random1.getText()).trim());

            getContentPane().setBackground(Color.RED);
        }
        else{

            SwingUtilities.updateComponentTreeUI(messageJLabel );
        } // end if

        if ( guess < number + 1 && guess > number-1 ) // guess is too low
        {
            messageJLabel.setText( "Correct!" );
            SwingUtilities.updateComponentTreeUI(messageJLabel );
            guessInputJTextField.setEditable(false);
        }

        // A class appearing inside the actionPerformed method.
        // This hides the class and is why the compiler could
        // not find the symbol.
        class GuessHandler implements ActionListener
        {
            public void actionPerformed( ActionEvent e )

                number = Integer.parseInt((random1.getText()).trim());

                if(Math.abs(number - guess) < Math.abs(number - guessOld))
                {
                    // Hotter
                    getContentPane().setBackground(Color.RED);

                }
            }
        }
    }

Change all of the above to this:

    class GuessHandler implements ActionListener
    {
        public void actionPerformed( ActionEvent e )
        {
            int guess = Integer.parseInt(guessInputJTextField.getText());
            number = Integer.parseInt((random1.getText()).trim());

            if(Math.abs(number - guess) < Math.abs(number - guessOld))
            {
                // Hotter
                getContentPane().setBackground(Color.RED);
            }
            else
            {
                // Colder
                getContentPane().setBackground(Color.BLUE);
            }

            guessOld = guess;

            if ( guess >= number )
            {
                messageJLabel.setText( "Too High." );
                SwingUtilities.updateComponentTreeUI(messageJLabel );
            }

            if( guess <= number )
            {
                messageJLabel.setText( "Too Low." );
                SwingUtilities.updateComponentTreeUI(messageJLabel );
            } // end if

            if ( guess < number + 1 && guess > number-1 )
            {
                messageJLabel.setText( "Correct!" );
                SwingUtilities.updateComponentTreeUI(messageJLabel );
                guessInputJTextField.setEditable(false);
            }
        }
    }
