整数(秒数)转换为时分秒格式(xx:xx:xx)

复制代码 代码如下:

// a integer to xx:xx:xx

public static String secToTime(int time) {

String timeStr = null;

int hour = 0;

int minute = 0;

int second = 0;

if (time <= 0)

return "00:00";

else {

minute = time / 60;

if (minute < 60) {

second = time % 60;

timeStr = unitFormat(minute) + ":" + unitFormat(second);

} else {

hour = minute / 60;

if (hour > 99)

return "99:59:59";

minute = minute % 60;

second = time - hour * 3600 - minute * 60;

timeStr = unitFormat(hour) + ":" + unitFormat(minute) + ":" + unitFormat(second);

}

}

return timeStr;

}

public static String unitFormat(int i) {

String retStr = null;

if (i >= 0 && i < 10)

retStr = "0" + Integer.toString(i);

else

retStr = "" + i;

return retStr;

}
