Java: Casting a ticket procedure

Voting City used: system.in, regular pattern,matcher, sorting interface comparable replication CompareTo sorting method

A class in the election monitor, according to the number of votes, and the highest number of votes on the first display

Design:

Student Student Class

Voting Menu Class

Voting Action Class

Accept input data classes
