hi,
i suppose to make simulation to cellphone. when press any digit ,it should appears on the display textfield to form a complete number. and when press the send button a message with"redialling+ the gigits pressed" appears on the textfield also when press redial button a message with " redialling+ the digits being pressed" appears on the textfield. but i have many errors as the following:

CellPhone.java:228: <identifier> expected

The following lines should be inside a method and not placed directly inside a class, you may place only member declarations / initialisations / methods or static blocks of code directly there.

Button1.addActionListener(listener);
        Button2.addActionListener(listener);
        Button3.addActionListener(listener);
        Button4.addActionListener(listener);
        Button5.addActionListener(listener);
        Button6.addActionListener(listener);
        Button7.addActionListener(listener);
        Button8.addActionListener(listener);
        Button9.addActionListener(listener);
        Button0.addActionListener(listener);
        astrButton.addActionListener(listener);
        boundButton.addActionListener(listener);

ya, i make it
but i need to make all the digits being pressed appear on the textfield with the statement for example" calling 345-675-4986" when press SEND button. Additionally i need to erase what ever is on the phone display screen and then display a message like (Redialing 276-5674-9853) when pressing REDIAL button ??

displayTextField.setText("3")

Now when a user dials a number I guess you might want to display the entire number to the user.
The way you are using setText() it would actually erase whatever is present in the Text Field with whatever value you set. If you want to display the entire number I replacing the above piece of code wherever it appears with:-

displayTextField.setText(displayTextField.getText() + "3");

The above piece of code will get whatever value is present in your TextField and append there to it, and set it as the new value in your text field. You will need to do the same for all your other numbers.
And when the user presses "SEND" store whatever value you have received for that Number in a variable for accessing it later and then prefix "Calling " to whatever you have in your text field like for ex:-

displayTextField.setText("Calling " + displayTextField.getText());

Similarly if say you have stored the original number in a variable called "number", if the user presses redial instead of prefixing "Calling " in the above statement use "Redialing " + number , when the "Redial" button is clicked
