The function is a bit too long and the variables are used throughout. To split the func- tion into smaller pieces we need to create a GuessStatisticsMessage class and make the three variables fields of this class. This provides a clear context for the three variables. They are definitively part of the GuessStatisticsMessage.

Candidate.java

private void printGuessStatistics(char candidate, int count) {
 String number;
 String verb;
 String pluralModifier;
 if (count == 0) {
 number = "no";
 verb = "are";
 pluralModifier = "s";
 } else if (count == 1) {
 number = "1";
 verb = "is";
 pluralModifier = "";
 } else {
 number = Integer.toString(count);
 verb = "are";
 pluralModifier = "s";
 }
 String guessMessage = String.format(
 "There %s %s %s%s", verb, number, candidate, pluralModifier
 );
 print(guessMessage);
 }
