public void theGame() {

}

class GuessHandler implements ActionListener {

int Guess;

Guess = Integer.parseInt(guessInputJTextField.getText());

if (Math.abs(number - Guess) < Math.abs(number - GuessOld)) {

getContentPane().setBackground(Color.RED);

} else {

if (Guess > number) {

}   
if (Guess == number) {
messageJLabel.setText("Correct!");
SwingUtilities.updateComponentTreeUI(messageJLabel);
guessInputJTextField.setEditable(false);

}
message2JLabel.setText("Number of Guesses: " + Guesses++);
}

}
