我们无法编译它，所以我们看不到你在说什么。
什么是jbp包？你为什么注释掉monthNamesListener类，但是你在程序中使用了它？
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 monthNamesListener class and yet you used it in the program?

我的程序编译我检查它之前我把它放在这里。你可以忽略jbp包。
my program does compile i checked it before i put it up here. and u can ignore the jbp package.

即使我删除该包的导入也不会编译。
找不到类monthNamesListener。如果你在一个单独的文件中编写代码，你也需要发布它。
It does not compile even if I remove the import for that package.
The class monthNamesListener is not being found. If you wrote its code in a separate file you will need to post that also.
