We are not able to compile it so we can't see what you are talking about.
What is the package jbp for? Why did you comment out monthNamesListe ner class and yet you used it in the program?

It does not compile even if I remove the import for that package.

The class monthNamesListe ner is not being found. If you wrote its code in a separate file you will need to post that also.

See this

Code:

 
add(monthNames);
monthNames.addItemListener(new monthNamesListener());

That is part of your code and the second line there uses a monthNamesListe ner class. If you can compile it, then you have the code for that class somewhere.

ok this time i add monthNames listener to my code, it should compile, but there is nothing in the monthNames listener body. i m having problem putting anything over there.

Yep, it's compiling and running now. You said the Calendar is not working. What do you want it to do now?

**skyblue** · Feb 23 '07, 06:00 AM

i want when user select the month and the date and the year then there should be line in the bottom saying that "today is this day" it should say the what day is it .
and if user select January then the date menu should show 31 choice but if the user choose february then the date part should show the 28 date and so on for the other months.
let me know if u have any more question.

You need to make use of listeners. ItemStateChange d on month dropdown should limit the range shown on days drop down. So go ahead and write the code for monthNamesListe ner class.
