자바 문자열 스위치 문이 적절한 스위치가되지 않습니다

Question

현재 switch 문에 문제가 있습니다. 나는 스위치 변수를 출력했지만 올바른 것으로 보이지만 원하는 스위치에 대한 print 문이 작동하지 않습니다. switch 문은 맨 아래에서 ~ 20 행에 있습니다.

"Person#Joe Gaucho#28000 Marguerite Parkway#949-582-4800#gaucho@sb.edu;" 
"Faculty#1234153524#1341244#1234150000#Adjunct;Employee#bgs210#20000#123455000;" 
"Person#Mickey Mouse#Disneyland#800 1Disney#mmouse@disney.com;" 
"Exit#" 

예상 출력은 다음과 같습니다 :

Answer 1

myClass의 값을 각 루프가 끝날 때 일부 기본값 (일반적으로 null)으로 재설정해야합니다.

• 그것은 유형 Person
• 그것은 새로운 Person 객체 myClass를 업데이트의 입력을 찾습니다 때문에이 반복 출력을 받고 있습니다. 루프 상단에서 진행
• 는 ERGO Person 남아, 새로운 Faculty
• myClass가 덮어 쓰기되지 않습니다 발견하고 그것을 다시 출력된다.
