如何分鐘轉換爲天，小時，分鐘

Question

如何分鐘轉換爲天時間，並在Java分鐘（我們這裏有一個星期，7天）

public String timeConvert(int time){ 
    String t = ""; 

    int h = 00; 
    int m = 00; 

    // h= (int) (time/60); 
    // m = (int) (time % 60); 

    // if(h>=24) h=00; 

    if((time>=0) && (time<=24*60)){ 
     h= (int) (time/60); 
     m = (int) (time % 60); 
    }else if((time>24*60) && (time<=24*60*2)){ 
     h= (int) (time/(1440)); 
     m = (int) (time % (1440)); 
    }else if((time>24*60*2) && (time<=24*60*3)){ 
     h= (int) (time/(2880)); 
     m = (int) (time % (2880)); 
    }else if((time>24*60*3) && (time<=24*60*4)){ 
     h= (int) (time/(2880*2)); 
     m = (int) (time % (2880*2)); 
    }else if((time>24*60*4) && (time<=24*60*5)){ 
     h= (int) (time/(2880*3)); 
     m = (int) (time % (2880*3)); 
    }else if((time>24*60*5) && (time<=24*60*6)){ 
     h= (int) (time/(2880*4)); 
     m = (int) (time % (2880*4)); 
    }else if((time>24*60*6) && (time<=24*60*7)){ 
     h= (int) (time/(2880*5)); 
     m = (int) (time % (2880*5)); 
    } 

    t =h+":"+m ; 
    return t; 
} 

我試過，但它不工作

謝謝

Answer 1

更簡短的方法。 （假設時間> = 0）

public String timeConvert(int time) { 
    return time/24/60 + ":" + time/60%24 + ':' + time%60; 
} 

Answer 2

如果使用Java 6，TimeUnit枚舉可能會有用。例如：

TimeUnit.HOURS.convert(10, TimeUnit.DAYS) 

這種靜態調用10天轉換成小時爲單位，並返回240您可以用納秒開始，隨着時光的結束時間單位玩。

其實TimeUnit可以從Java 5中獲得，但是在版本6中增加了更多的單元。

--EDIT-- 現在，我更瞭解您的問題，請使用除法和餘數方法，如同羅曼的回答一樣。我的提示僅適用於轉換爲單個時間單位。

Answer 3

如果你想自己做，就換個方法吧。

1. 除以60 * 24（這將讓天數。）數
2. 除以其餘由60（這會給你的小時數。）
3. 的＃剩餘2是分鐘數。

Answer 4

1）您的代碼是重複的。這是我認爲糟糕代碼的一個標誌。

2）除數不應隨天數而改變，因爲天數與一小時內的分鐘數無關。

除此之外，看看Romain Hippeau的方法，他告訴你如何去做。

Answer 5

答案是：

public String timeConvert(int time){ 
    String t = ""; 

    int j = time/(24*60); 
    int h= (time%(24*60))/60; 
    int m = (time%(24*60)) % 60; 



    t =j + ":" + h + ":" + m; 
    return t; 
} 

你怎麼看待這個代碼是什麼？

Answer 6

我使用此代碼。它也可以提供幫助。

private String getText(int minutes){ 

    int weeks = minutes/10080; 
    int aboveWeeks = minutes % 10080; 
    int days = aboveWeeks/1440; 
    int aboveDays = aboveWeeks % 1440; 
    int hours = aboveDays/60; 
    int aboveHours = aboveDays % 60; 
    int minute = aboveHours/60; 

    if(weeks > 0 && days > 0) { 
     if(weeks > 1 && days > 1){ 
      return weeks + " weeks " + days + " days before"; 
     } else { 
      return weeks + " weeks " + days + " day before"; 
     } 
    } else if (weeks > 0){ 
     if (weeks > 1){ 
      return weeks + " weeks before"; 
     } else { 
      return weeks + " week before"; 
     } 
    } else if(days > 0 && hours > 0){ 
     if(days > 1 && hours > 1){ 
      return days + " days " + hours + " hours before"; 
     } else { 
      return days + " days " + hours + " hour before"; 
     } 
    } else if(days > 0){ 
     if (days > 1){ 
      return days + " days before"; 
     } else { 
      return days + " day before"; 
     } 
    } else if(hours > 0 && minute > 0){ 
     if(hours > 1 && minute > 1){ 
      return hours + " hours " + minute + " minutes before"; 
     } else { 
      return hours + " hours " + minute + " minute before"; 
     } 
    } else if(hours > 0){ 
     if (hours > 1){ 
      return hours + " hours before"; 
     } else { 
      return hours + " hour before"; 
     } 
    } else { 
     if (minutes > 1){ 
      return minutes + " minutes before"; 
     } else { 
      return minutes + " minute before"; 
     } 
    } 
}

class time{ 
    public static void main (String args[]){ 
     System.out.println("Hello"); 
     int duration=1500; 
     String testDuration = ""; 

     if(duration < 60){ 
      testDuration = duration + " minutes"; 
     } 
     else{ 

      if((duration/60)<24) 
      { 
       if((duration%60)==0){ 
        testDuration = (duration/60) + " hours"; 
       } 
       else{ 
      testDuration = (duration/60) + " hours," + (duration%60) + " minutes"; 
       } 
      } 
      else{ 

       if((duration%60)==0){ 
        if(((duration/60)%24)==0){ 
         testDuration = ((duration/24)/60) + " days,"; 

        } 
        else{ 
        testDuration = ((duration/24)/60) + " days," + (duration/60)%24 +"hours"; 
        } 
       } 
        else{ 
       testDuration = ((duration/24)/60) + " days," + (duration/60)%24 +"hours"+ (duration%60) + " minutes"; 
        } 
      } 
     } 

     System.out.println(testDuration); 
    } 
}
