Write the code that would inside of a single handler/listener for both buttons. Use the following objects:

JButton plusButton

JButton minusButton

JTextField resultTextField

public void actionPerformed(ActionEvent e) {

   JTextField resultTextField = new JTextField();

int number1 = Integer.parseInt(inputNumber1TextField.getText());

int number2 = Integer.parseInt(inputNumber2TextField.getText());

if (e.getSource() == plusButton) {

int result = number1 + number 2;

resultTextField.setText (result);

plusButton.setEnabled(false);

minusButton.setEnabled(false);

}

if (e.getSource() == minusButton) {

int result = number1 - number 2;

resultTextField.setText (result);

plusButton.setEnabled(false);

minusButton.setEnabled(false);

}

}
