The way the code is currently written, you are adding an empty action listener to your elements ('this' aka FinalProject class has an empty implementation of ActionListener), so all those new ActionListener statements don't do anything because they are not added as listeners to your gui elements. Try creating inner or anonymous classes and add those to the buttons

//anonymous  button.addActionListener(new ActionListener(){ public void actionListener(ActionEvent e){   } }); //inner class private class ButtonExample implements ActionListener{ public void actionPerformed(ActionEvent e){   } } .... button.addActionListener(new ButtonExample());

Do you see which actionPerformed method is being executed?
If not add a println() to all of them with different messages, compile and execute the code, press the button and see which method is called: System.out.println("aP=" + e); // shown the event for this action

You have many orphaned ActionListeners that need to be added to a button. I asked about them in my post#4

You can connect some of the ActionListeners by changing this:

 button.addActionListener(this);   new ActionListener(){

to this:

 button.addActionListener(   new ActionListener(){

and add a needed ) at the end of the ActionListener definition.

The code change makes the following ActionListener the actionlistener vs having the main class (this) be the action listener.

Did you add this statement to your actionPerformed() method:
System.out.println("aP=" + e); // shown the event for this action

It will show you when a button is pressed and what button was pressed

Please copy and paste the full text of the error here. You have left out some of the important info in the message!!!

Did you look at what I posted?????
Go look again. I did NOT put the ) beside the (.
The ) must go at the end. For example:

 button.addActionListener(   new ActionListener(){ public void actionPerformed(ActionEvent e) { e.getActionCommand(); int length=Integer.parseInt(text4.getText()); int width=Integer.parseInt(text5.getText()); int depth=Integer.parseInt(text6.getText());   if (e.getActionCommand().equals("Enter")) { int volume = ((length * width) * depth); JOptionPane.showMessageDialog(null, "The Volume is:"+volume,"for your pool.", JOptionPane.INFORMATION_MESSAGE); } } }[COLOR="Red"])[/COLOR];

That is how you create an anonymous class for the listener.

Which means you didn't copy him exactly.
