Specification For this project, implement a record keeping application for bicycle racing. The implementation should include 3 Java classes: o Main (provided to you) o Race (you should implement this class) o Racer (you should implement this class) Here are the class diagrams for the two classes you should implement: ace Racer Race : Racerl] numRacers : int maxRaceSize : int bibNumber: int -name: String age: int +Race(maxRaceSize: int) addRacer(racer : Racer): int printRace) : void +Racer(bibNumber: int, name : String, age: int) printO:void getAge0 int Recall that - means private and + means public. Thus, the instance variables in the classes should be private and the constructors and methods should be public.Explanation / Answer
Working on it dude... please wait
