    Hello idols , im IT student beginner.

    public class Calculator extends Applet implements ActionListener {

    Button btnAdd, btnSubtract, btnMultiply, btnDivide;
    Label lblFirstDigit, lblSecondDigit, lblAnswer;
    TextField txtFirstDigit, txtSecondDigit, txtAnswer;


    public void init() {

    lblFirstDigit = new Label("Enter the first integer: ");
    txtFirstDigit = new TextField(10);
    lblSecondDigit = new Label("Enter the second integer:");
    txtSecondDigit = new TextField(10);
    btnAdd = new Button("+");
    btnSubtract = new Button("-");
    btnMultiply = new Button("*");
    btnDivide = new Button("/");
    lblAnswer = new Label("Answer: ");

    }

    public void actionPerformed(ActionEvent e) {

    double firstDigit = Double.parseDouble(txtFirstDigit.getText());
    double secondDigit = Double.parseDouble(txtSecondDigit.getText());

    if (e.getSource() == btnAdd)
    txtAnswer.setText(Double.toString(firstDigit+secon dDigit));

    if (e.getSource() == btnSubtract)
    txtAnswer.setText(Double.toString(firstDigit-secondDigit));

    if (e.getSource() == btnMultiply)
    txtAnswer.setText(Double.toString(firstDigit*secon dDigit));

    if (e.getSource() == btnDivide)
    txtAnswer.setText(Double.toString(firstDigit/secondDigit));



    }

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Can you explain what you are trying to do? The images are hard to see.
    Is your problem with laying out the components in the GUI?
    If you don't understand my answer, don't ignore it, ask a question.

    Enter the first integer: ---TEXTFIELD----
    Enter the second integer: ---TEXTFIELD----
    + - * /

    Answer: ---TEXTFIELD----

    Enter the second integer: ---TEXTFIELD----
    + - * / Answer: ---TEXTFIELD----

    What do you mean by "output"?
    Are you talking about changing the layout of components on the GUI?

    See the tutorial:
    Lesson: Laying Out Components Within a Container (The Java™ Tutorials > Creating a GUI With JFC/Swing)
    If you don't understand my answer, don't ignore it, ask a question.
