Determinant Finite Automata (JFLAP)

I have a DFA question (Determinant Finite Automata) . We are using JFLAP to construct the automata. I cannot figure this question out to save my life! Here it is

"DFA to recognize the language of all strings that have an even number of zeros and an odd number of ones."

So the alphabet开发者_开发问答 is {0,1} and only using 0,1. So I need to build an automata that recognizes an even number of zeros and an odd number of ones.

I don't know whether my understanding is right. I could give you the description in Grail format that generate an even number of zeros and an odd number of ones.
