My apologies if I'm wrong, I'm at work and can't check out the API right now.(navy so I'm not allowed any excess material here) But the method should be as simple as
comboBox.getSelectedItem(); //should return an Object, cast it to String if need be
//or
comboBox.getSelectedIndex();
I hope this helps, have a good day. (It's just off of the top of my head.)

You'd think that, but no. :S
I tried that and it works only for the selected item in the LAST combobox that was modified, but when you have more than one row in a jtable and each one of those rows has a combobox that's referenced by the same variable (combobox) it only returns the last change that was made to the object.
What I need to do is I have a jtable and I need to go through all of the rows to record those values in a database.

I have a class JPanel that I want to add other JPanels onto during run-time. I can add a JPanel using the NetBeans IDE for "design", but the IDE will not let me dynamically add a new JPanel and let me position it on the main JPanel . When I look at the documentation, it appears that there are inherited methods that would allow this type of operation, such as setLocation(int, int). The IDE complains about this method, and the list of available methods that appears when editing the code, has a very limited set. Is there a way around this using the IDE?
Thanks for your time.

I would rename your class to something more appropriate if I were you.
If you have a look at the code Netbeans generates with the designer, then you will see something which looks like this.
JPanel jp = new JPanel();
[InsertParentControlHere].add(jp);
Add that in the code where you need it.

I was just using this as a generic example. The actual name is not JPanel. I was going to try and use this "JPanel" to draw graphics on and place it on another "JPanel". I think that the better approach is just to draw directly to the "JPanel" without adding a whole bunch of smaller "JPanel"s.
Thanks for replying.

Apologies, I misunderstood.

Agreed, I see what you mean about inheritence now. Overriding the paintComponant method should do the trick. Have a look at this[^], it may help.

Thank you

Err, this has nothing todo with Java; unless that happens to be the language used in your school.
Alternatively, if this really is for work, use a sheet of paper that visitors sign in and out on.

My work here is done.

with mobile ,Can you tell me java or c# can easier to develop and more popular at The developing country,example viet nam
thanks

It really depends on the type of mobilephones you want to develop for.
I'd say that for most of the simple mobile phones, you'll better go with Java, but there are more and more smartphones coming up with windows mobile which will perfectly fit with C# (Compact Framework).
I won’t not use no double negatives.

Here is my code of JSP
<% if(request.getParameter("txtTextInput")!=null && request.getParameter("LangGroup").equals("English") ) {
String file=CreateSoundFile( request.getParameter("txtTextInput"), "en");
%>
<embed src="<%=file%>" ></embed>
while CreateSoundFile creates the sound file and give back its path
but the sound file is not played on the client and if the program is being run 2nd time the previous text is being played on the client browser where as the file in the folder on server is changed.
why the file is not downloaded at client when it exists on the serve  r

i have postfix installed on my ubuntu and test it to send message to other user in my localhost, and i found no problem using it. But when i try to fetch the message using pop3, i do :
out.write(("USER :"+user+"\r\n").getBytes());<br />
out.write(("PASS :"+pass+"\r\n").getBytes());
and i always get the respon :
+OK Hello there.
+OK Password required.
-ERR Login failed.
+OK Better luck next time.
