轉換秒到人類可讀的格式MM：SS的Java

Question

我如何轉換的秒長整型人類可讀的格式

MM:SS 

只有SS應該是0填充，以便

long = 67 -> 1:07 

Answer 1

使用整數除以60來將秒數轉換爲整個分鐘。秒數的模數（％）爲60會給出「剩餘」秒數。然後使用字符串轉換來檢查0填充的必要性。

int minutes = (total/60); 
int seconds = (total % 60); 
String secs = Integer.toString(seconds); 
if (seconds < 10) { 
    secs = "0" + seconds; 
} 
String time = minutes + ":" + secs; 

Answer 2

一些算術：

long min = value/60; 
long second = value % 60 ; 
String value = min + ":" + (second > 10 ? "" : "0") + second; 

Answer 3

String readable = String.format("%d:%02d", s/60, s%60); 

Answer 4

int duration = 90; 
int min = duration/60; 
int sec = duration%60; 
String formattedTime = String.format("%d:%02d",min,sec);
