Basic Calculator

[trtoy]

So as you can see I am very new to this...

I am getting an error while using textpad. The error is "Desktop\BasicCalculator.java:84: illegal character: \29"

I need to add other functions but I thought I would try to run it first and it doesn't even work with just the addition. Here is thy code.

Thanks people!

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class BasicCalculator extends JFrame{
private static final int FRAME_WIDTH = 150;
private static final int FRAME_HEIGHT = 120;

// Keeps track of the current operation (subtract, add, etc)
private static final int NO_OPERATION = 0;
private static final int ADDITION = 1;
public static int operation = NO_OPERATION;

public static JTextField textFieldDisplay;
public static double Value1 = 0; // holds the value before the operation

public static void main(String[] args) {
// Set up the user interface
JFrame frame = new JFrame();
JPanel buttonPanel = new JPanel();
frame.add(buttonPanel);

// create two buttons, plus and equal and a text box for answers
textFieldDisplay = new JTextField(10);
buttonPanel.add(textFieldDisplay);
JButton buttonPlus = new JButton(" + ");
buttonPanel.add(buttonPlus);
JButton buttonEqual = new JButton(" = ");
buttonPanel.add(buttonEqual);

frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
frame.setTitle("Basic Calculator");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
frame.setVisible(true);


// called when the equal sign '=' is pressed
class EqualSignListener implements ActionListener {

public void actionPerformed(ActionEvent event)
{
double Value2 = Double.parseDouble(textFieldDisplay.getText());
if (operation == ADDITION) {
// plus sign pressed before the equal sign
Value2 += Value1;
}
// Convert from a answer to a string
Double answer = new Double(Value2);
textFieldDisplay.setText( answer.toString() );
// Reset the operation to show no current operation
operation = NO_OPERATION;
}
}

// called when a plus sign '+' is pressed
class PlusSignListener implements ActionListener {
public void actionPerformed(ActionEvent event)
{
Value1 = Double.parseDouble(textFieldDisplay.getText());
operation = ADDITION;
}
}

// Add the methods that will be called when these buttons are pressed
ActionListener plusSignListener = new PlusSignListener();
buttonPlus.addActionListener(plusSignListener);

ActionListener equalSignListener = new EqualSignListener();
buttonEqual.addActionListener(equalSignListener);

}
}

Fixed thanks for looking. Just had to take a break.
