Java Programming

Having read http://download-llnw.oracle.com/javase/6/docs/api/java/lang/String.html#split%28java.lang.String,%20int%29, I know that the second argument is used to limit the array's size. For example, if there 5 tokens and you put the number 4, then the last component of the array would have the two tokens including the delimiter. I also know that any negative number means infinity array size.

My questions are:_
*1)* Does the split() method with one argument implicitly have a negative number as the limit argument?
*2)* I read that 0 is the same as a negative number except that it also discards trailing empty strings. My problem is that I don't understand the examples nor can I visualize a situation in which there are no trailing empty strings. I need major elaboration (beyond the API's description) for the trailing empty strings situation so I would appreciate it if someone could give me that.

I think that's all I don't get so I'll finish my post off here.

Any input would be greatly appreciated!
Thanks in advance!
