How about this for times


int whatever = Integer.parseInt(textField.getText());

textField.setText(" ");

// now here's where I'm not sure what'll happen

int whatever2 =...

x = x + 1;

What is this doing?

How is that value being saved?

I can't find where x was initialized.

I'm pretty sure your error is in this part

public void actionPerformed(ActionEvent e) {
if (e.getSource()==b1) {
String text = textField.getText();
...

And you'd have to have

button.addActionListener(this);

On a side note, you could just define all your buttons in a constructor.

But if you do that, they probably shouldn't be static anymore.

Oh....wait, that's what it's supposed to do.

But I noticed that the word "Final" was highlighted as a keyword or as a class.

textField.setText(text+"3")

I doubt that's adding anything.

All it appears to do is append a 3 to the String text.
