Java中整数(秒数)转换为时分秒格式(xx:xx:xx)

可直接使用

public 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);elseretStr = "" + i;return retStr;}
