추가 시간 프로그램 컴파일러 오류

Question

내 프로그래밍 수업 시간과 올바른 분, 초 양 (NO보다 큰 59)

import java.util.Scanner; 

public class AddingTime { 

public static void main (String[] args) { 

    Scanner kbReader = new Scanner(System.in); 

    System.out.println("Welcome to AddingTime!"); 


    // First Addend 

    System.out.println("Enter the days amount for the first addend (if none print 0): "); 

    int firstAddendDays = kbReader.nextInt(); 

    System.out.println("Enter the hours amount for the first addend (in none print 0): "); 

    int firstAddendHours = kbReader.nextInt(); 

    System.out.println("Enter the minutes amount for the first addend (if none print 0): "); 

    int firstAddendMinutes = kbReader.nextInt(); 

    System.out.println("Enter the seconds amount for the first addend (if none print 0): "); 

    int firstAddendSeconds = kbReader.nextInt(); 


    // Second Addend 

    System.out.println("Enter the days amount for the second addend (if none print 0): "); 

    int secondAddendDays = kbReader.nextInt(); 

    System.out.println("Enter the hours amount for the second addend (in none print 0): "); 

    int secondAddendHours = kbReader.nextInt(); 

    System.out.println("Enter the minutes amount for the second addend (if none print 0): "); 

    int secondAddendMinutes = kbReader.nextInt(); 

    System.out.println("Enter the seconds amount for the second addend (if none print 0): "); 

    int secondAddendSeconds = kbReader.nextInt(); 

    int totalSeconds = firstAddendSeconds + secondAddendSeconds; 


    if (totalSeconds >= 60) { 

     // Total Seconds if totalSeconds is larger than 60 

     totalSeconds = totalSeconds % 60; 


     // Extra minutes from totalSeconds in a decimal form 

     double minutesFromSeconds = totalSeconds/60; 

     // Changing the above into a integer form of minutes 

     int intMinutesFromSeconds = (int)minutesFromSeconds; 

    } 

    int totalMinutes = firstAddendMinutes + secondAddendMinutes + intMinutesFromSeconds; 

    if (totalMinutes >= 60) { 

     // Total minutes if totalMinutes is larger than 60 

     totalMinutes = totalMinutes % 60; 

     // Extra hours from totalMinutes in a decimal form 

     double hoursFromMinutes = totalMinutes/60; 

     // Changing the above into an integer form of hours 

     int intHoursFromMinutes = (int)hoursFromMinutes; 

    } 

    int totalHours = firstAddendHours + secondAddendHours + intHoursFromMinutes; 

    if (totalHours >= 24) { 

     // Total hours if totalHours is larger than 24 

     totalHours = totalHours % 24; 

     // Extra days from totalHours in a decimal form 

     double daysFromHours = totalMinutes/24; 

     // Changing the above into an integer form of days 

     int intDaysFromHours = (int)daysFromHours; 


    } 

    int totalDays = firstAddendDays + secondAddendDays + intDaysFromHours; 

    System.out.println("Your total calculated time is " + totalDays + "days" + totalHours + "hours" + totalMinutes + "minutes" + totalSeconds + "seconds");; 


    } 

}

로 변환을 추가하는 프로그램을 만들도록 지시했다 이 코드를 컴파일하면 변수 intMinutesFromSeconds, intHoursFromSeconds 및 intDaysFromHours에서 기호 오류를 찾을 수 없다는 메시지가 나타납니다. 그러나 나는 내가 잘못한 것을 이해하지 못한다.

Answer 1

범위에 문제가있을 수 있습니다 (대괄호 안에 선언 된 것은 대괄호를 닫은 후에 사용할 수 없습니다). 자바가 무엇을하고 있는지 확신 할 수 없습니다.

if (totalSeconds >= 60) { 
    int intMinutesFromSeconds = (int) minutesFromSeconds; 
} 

int totalMinutes = intMinutesFromSeconds + ... 

당신처럼 뭔가를 해결할 수 있습니다 : 그것은 아직도 나에게 변수 intMinutesFromSeconds의 오류를 제공

int intMinutesFromSeconds = 0; 
if (totalSeconds >= 60) { 
    intMinutesFromSeconds = (int) minutesFromSeconds; 
} 

int totalMinutes = intMinutesFromSeconds + ...
