Java Cell phone question

I am wondering if there is a way to write a small java program that will check the time of day and set your volume control depending upon time of day. I am a student and would love to be able to have my volume turned off all the way while at school and not have to worry about remembering to turn it back up.

Is this possible on a Sony Ericsson Z525a?

So far I have only had one semester of Java programming, so while this project may be rather simple to an experienced programmer, it could be a pretty tough learning experience for me. But before I begin, it would help to know if it is even possible.

Thanks in advance!
