+검색이 LISt는 느려 || SET/MAP은 빠르다
+h1 == h2 는 서로 다른 주소이므로 '=='가 들어갔어도 비교는  equals로 한다
+ㄴ> 비교하는 코드 틀 :: [h1.compareTo(h2)]
+[equals() 특징] :: equals가 있으면 같은 내용은 지워진다
+
+[얕은 복사 (주소만 복사) || 깊은 복사(주소 달라, 내용 같아)]
+[얕은 복사 코드의 틀 ] :: Book h2 = h1.clone();
+[깊은 복사 코드의 틀 ] :: copy.author = this.author.clone();
+
+[ 단축키 ]
