what is the standard number of parameters that a java method should have?

I am writing a program that checks the number of parameters of a methods and prints out a warning message (its a codesmell program) If there are more than what the standard is, the problem is that I don't know what the agreed number is. I have looked around and not had any luck. Can anyone tell me or at least point me in the right direction?

There is no standard limit on the number of parameters you can specify in Java, but according to "Code Complete" (see this post) you should limit the amount of parameters to about 7, any more and it will have a negative effect on the readability of your code.
