Write a java code to implement four new functions DFA

Union: Given Two DFAs, M1 and M2, create a DFA which accepts the union of the languages of M1 and M2.

Intersection: Given Two DFAs, M1 and M2, create a DFA which accepts the intersection of the languages of M1 and M2.

Difference: Given Two DFAs, M1 and M2, create a DFA which accepts the set difference of the languages of M1 and M2, that is, L(M1) - L(M2), the set of strings accepted by M1 but not M2.

Complement: Given DFA M, create a DFA which accepts the complement of the language of M.
