Set은 List와는 다르게 객체(데이터)를 중복해서 저장할 수 없다. 또한 저장된 객체(데이터)를 인덱스로 관리하지 않기 때문에 저장 순서가 보장되지 않는다. Set 컬렉션을 구현하는 대표적인 클래스들은 HashSet, TreeSet, LinkedHashSet 등이 있다. Set - HashSet, TreeSet, LinkedHashSet package groom; import java.io.BufferedReader; import java.io.InputStreamReader; import java.util.HashSet; import java.util.Set; import java.util.StringTokenizer; public class CardCollect { public static voi..
