Question

Add the following methods to the class provided:

*getAndConfirmVotes - a non-static method that gets an individuals votes, confirms them, and then records them

*getAVote(String name1, String name2) - a private method that returns a vote choice for a single race from an individual (0 for no choice, 1 for the first candidate, and 2 for the second candidate)

*getVotes - a private method that returns a vote choice for president and vice president from an individual

*confirmVotes - a private method that displays a persons vote for president and vice president, asks whether the voter is happy with these choices, and returns true or false according to a yes-or-no response

*recordVotes - a private method that will add an individuals votes to the appropriate static variables

*Then finally create a MainClass that will conduct an election. The candidates for president are Annie and Bob. The candidates for vice president are John and Susan. Use a loop to record the votes of many voters. Create a new Vote Recorder object for each voter. After all the voters are done, present the results.
