Question

快速提问。

是否有更智能/更时尚的方式将分钟转换为更易读的格式，只显示最重要的数字？

我正在使用Android Studio的Java。

public String MinutesToHumanReadable(Long minutes) {

...

}

即

2 mins = "2 mins"
45 mins = "45 mins"
60 mins = ">1 hr"
85 mins = ">1 hr"
120 mins = ">2 hrs"
200 mins = ">3 hrs"
1500 mins = ">1 day"

我的代码非常繁琐，草率，有点难以辨认。

public String MinutesToHumanReadable(long minutes) {
    String sReturn = "";

    if (minutes > 515600) {
        sReturn = "> 1 yr";

    } else if (minutes > 43200) {
        sReturn = (minutes / 43200) + " mths";

    } else if (minutes > 10080) {
        sReturn = (minutes / 10080) + " wks";

    } else if (minutes > 1440) {
        sReturn = (minutes / 1440) + " days";

    } else if (minutes > 60) {
        sReturn = (minutes / 60) + " hrs";

    } else {
        //<60
        sReturn = minutes + " mins";

    }

    return sReturn;
}

非常感谢， Ĵ

嗯有可能，我明白了，我为此感到自豪！ :) 请注意，只需更改这两个数组中的值，即可轻松添加任何其他值而无需更改方法本身。例如，如果“年”对你来说还不够，你可以添加“几十年”和“几个世纪”......

如果输出值超过1，此代码也会在末尾添加“s”字母。

public class SuperMinutesChangerClass {
    public static int[] barriers = {1, 60, 60*24, 60*24*7, 60*24*365, Integer.MAX_VALUE};
    public static String[] text = {"min", "hr", "day", "week", "year"};

    public static String minutesToHumanReadable(int minutes){
        String toReturn = "";
        for (int i = 1; i < barriers.length; i++) {
            if (minutes < barriers[i]){
                int ammount = (minutes/barriers[i-1]);
                toReturn = ">" + (ammount) + " " + text[i-1];
                if (ammount > 1){
                    toReturn += "s";
                }
                break;
            }
        }
        return toReturn;
    }         
}

示例输入：

    public static void main(String[] args) {
        System.out.println(minutesToHumanReadable(10));
        System.out.println(minutesToHumanReadable(60));
        System.out.println(minutesToHumanReadable(61));
        System.out.println(minutesToHumanReadable(121));
        System.out.println(minutesToHumanReadable(8887));
        System.out.println(minutesToHumanReadable(9999743));
    }

输出是：

>10 mins
>1 hr
>1 hr
>2 hrs
>6 days
>19 years

Answer 2

我会使用一些虚拟if/else if/else语句：

public static String convert(int minutes) {
  if(minutes < 60) {
    return String.format("%d mins", minutes);
  } else if(minutes < 1440) { //1 day = 1440 minutes
    return String.format("%d hrs, %d mins", minutes/60, minutes%60);
  } else {
    return String.format("%d days", minutes / 1440);
  }
}

测试

System.out.println(convert(84));

输出：

1小时，24分钟

Answer 3

也许这有助于你

private static final int MINUTES_PER_HOUR = 60;
private static final int MINUTES_PER_DAY = MINUTES_PER_HOUR * 24;

public String minutesToHumanReadable(long minutes) {
    if (minutes > MINUTES_PER_DAY) {
        return String.format("> %d days", minutes / MINUTES_PER_DAY);
    } else if (minutes > MINUTES_PER_HOUR) {
        return String.format("> %d hours", minutes / MINUTES_PER_HOUR);
    }

    return String.format("%d minutes", minutes);
}

将分钟转换为人类可读格式
