static,

This took, was in the same class, but because of the format problem, I am like that, I use the a, b, c three classes, a good class to encapsulate the corresponding dictionary, class b write method, data problems is that after entering the class b dictionary data is normal, but in class c is going to call a dictionary data, data loss, should be I build problems, cause when I went to class c tuning, data appear problem, I go to invoke the static across class I also tried to have problems, may be I use problem, please some directions superiors, or what is the effective way to solve it,

3. When multiple use, suggest use thread safety in the dictionary
