Hinzufügen von Zeitprogramm Complier Fehler

Question

Meine Programmierung Klasse wurde angewiesen, um ein Programm zu machen, die Zeit hinzufügen würde und es in die richtigen Minuten und Sekunden Menge (nicht größer als 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");; 


    } 

}

Umwandlung Wenn ich diesen Code kompiliere, sagt er mir, dass ich einen Symbolfehler in den Variablen intMinutesFromSeconds, intHoursFromSeconds und intDaysFromHours nicht finden kann. Ich verstehe jedoch nicht, was ich falsch gemacht habe.

Answer 1

Es kann ein Problem mit dem Oszilloskop sein (die in den Klammern angegebenen Zeichen sind möglicherweise nicht verfügbar, nachdem die Klammern geschlossen wurden). Nicht sicher was Java macht.

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

int totalMinutes = intMinutesFromSeconds + ... 

Sie können es mit etwas reparieren wie:

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

int totalMinutes = intMinutesFromSeconds + ...
