Java에서 BigDecimal, String 및 LocalDate로 이러한 문제를 처리하는 방법은 무엇입니까?

현재 다음과 같은 예외가 발생합니다. 문제는 Price 클래스의 생성자 부분에 있습니다. 이 문제를 어떻게 처리 할 수 ​​있습니까? 가격 2.29 및 날짜 10202017을 문자열로 전달할 수 있어야합니다.

Price price = new Price("2.29", "10/20/2017");

그러나 Price 클래스는

private BigDecimal price;
private LocalDate effectiveDate;

나는 전환이 잘되지 않는다. 누구든지 이것을 달성하고 나를 안내하는 방법을 보여줄 수 있습니까?

바람직한 출력 :

품목 번호 : 1 품목 : 칠면조 샌드위치 범주 : 식료품 UPC : 1001 가격 : 2.29
