"Download" Business Rules

Question

I wasn't sure where to post this, but:
Let's say I have boolean code sitting in a file on my computer that probably runs in java... :)
I want to read the file into my program and use its boolean code to decide whether or not to do things (since there are many different types of business rules, but some of the same things are happening just at different times). The code doesn't really stop to recompile, after reading it, the program just uses the newly uploaded code.
Is this possible, where would I find resources for this, what is it called? Any ideas would be appreciated.

Answer 1

...yeah all your comments were ridiculously helpful, not looking for more clearificationOk, fine. You go off and use the Java compiler tooling to do this. Then when you find out that the solution is non portable and doesn't really help with whatever your "real" problem is, that's all your problem.
, looking for different ways, "names" of methods.Ok. Use Google. Seriously, if you know enough about this problem to know you need to dynamically compile source code, you must know enough to find the solution using Google. You don't need my help.
If you do need help, then by definition you don't know everything about the problem. In which case you don't know that this is the best solution. But I can't help you find the best solution unless you tell me the problem you're trying to solve instead of the solution you've selected but can't actually achieve.
It's not my problem either way.
