Event handeling variable changes. Is this possible?

Hey,

I'm working on a java-beans project and I am trying to come to find a way to signal an event when a variable changes. Basically looking for a way to constantly send the refreshing data to the listener bean.

I can easily get it to work send the data with pushing a button but this is supposed to monitor a constantly changing temperature and send it to the listener bean.

Any ideas?

Thanks.
