,691 당신이 salary이 int 매개 변수가 주어진 할을 기대 않습니다 -

가

public void setSalary(int salary){ 
    salary.setMonthlySalary(salary); 
} 

salary.setMonthlySalary에서 봐 :

Answer 1

이하지 생성자 문제인가?

this.salaray.setMonthlySalary(salary)에 전화하기로 한 것 같습니다.

그런데 문제는 그게 아닙니다. 그냥 코드를이기는, 나는 이것이 당신이 원하는 것을하지 않습니다 의심 :이 필드를 참조 때

public static void setCount(int count){ 
    count =count ; 
} 

당신은 정말 당신의 코드는 매개 변수를 참조하면 이해할 필요합니다. 이 둘 사이에 혼란 스러울 경우 다른 이름을 사용하십시오. 또한

:

• 왜 만 int으로 급여가 구축 될 수 있도록되어 있지만, 다음 double로 저장?
• 처음에는 통화 값에 double을 사용하지 않아야합니다. 암시 적 크기 조정 (예 : 센트 수)을 사용하여 int을 사용하거나 BigDecimal을 사용하십시오. 오류 메시지로

Answer 2

은 당신이 Employee의 int 값 역 참조 그것은 급여를 언급하지 않고 할 수 없음을 의미

Resource: Employee.java 
int cannot be dereferenced 

말한다.

public void setSalary(int salary){ 
    salary.setMonthlySalary(salary); 
} 

당신이이 같은 이름의 필드를 숨기는 int입니다 salary라는 매개 변수가 있습니다.이 문제를 해결하려면

public void setSalary(int salary){ 
    this.salary.setMonthlySalary(salary); 
} 

이상은 다른 목적으로 사용되는 이름을 다른 것으로 만드는 것입니다.

public void setSalary(int monthlySalary){ 
    salary.setMonthlySalary(monthlySalary); 
} 

오류가 발생한 위치를 찾고 문제를 해결하는 데 도움이되므로 IDE의 코드를 살펴 보시기 바랍니다.
