1. 문제
안녕하세요!
지난주 수업 내용이었던 대용량 데이터 가공, 분석에 대한 학습을 주말에 회고하면서 코드를 그대로 구현하고, 수정해 보았습니다.
두 번 복습을 하는 가운데 도출된 자료값이 상이하여 분석하던 도중, 어떤 과정에서 잘못된 처리를 하였는지 찾지 못해서 질문을 드립니다. 
1.
첫 번째는 강사님께서 알려주신 과정대로 진행하였습니다. (중간중간 메서드를 수정하지 않고 새로운 메서드를 생성하였습니다). → 수업 때 도출됐던 값과 같은 값이 나왔습니다.
2.
두 번째는 메서드를 수정하지 않고 새롭게 만들다 보니 한 번의 과정으로 모든 로직을 진행할 수 있을듯하여 중간 과정을 생략하여 코드를 구성하였습니다. → 수업과 다른 값이 도출되었습니다.
2. 도출된 값

3. PopulationStatistics.java 전체 코드
두 번째 케이스를 진행하면서, 첫 번째에 있던 parseForHeatmap, readByLineForHeatmap을 삭제하고 처음 parse 하면서 얻었던 PopulationMove 객체들의 값을 이용하여 분석을 진행하였습니다.
해당 위의 코드들은 수업 진행하면서 parse() 메소드를 수정하였지만, 복습하는 과정에서 코드를 유지하고 싶어서 메서드를 추가로 제작하였음을 말씀드립니다.
