I used above code to play an audio in blackberry. But it gives an exception error as mentioned in below.

推荐答案

您不能对在编程中发现的每个问题都提出一个问题(...开发中...).

请 购买一本书.并在开始进行Blackberry开发之前尝试学习基本的Java.

而且，请不要以为您会在互联网上学到一切-您不会..因为网络要求您输入没有的关键字.一本书不需要关键字. Big 优势！

You can''t open a question on every single issue you find in your programming (...not to talk about development...).

PLEASE buy a book. And try to learn basic Java before you turn into Blackberry development.

And please do not think you''ll learn everything on the internet - You can not. Because the web demands for keywords that you do not have. A book does not need keywords. Big advantage!
