Java将Long类型转换为时分秒

	public static String getTime(Long time) {
		String timeStr="";
		if (time==null){
			return null;
		}
		//时
		Long hour = time / 60 / 60;
		//分
		Long minutes = time / 60 % 60;
		//秒
		Long remainingSeconds = time % 60;
		//判断时分秒是否小于10……
	   if (hour < 10){
		   timeStr =  minutes + "分" + remainingSeconds+"秒";
		}else if (minutes < 10){
		   timeStr =  minutes + "分" + remainingSeconds+"秒";
		}else if (remainingSeconds < 10){
		   timeStr =  minutes + "分" + "0" + remainingSeconds+"秒";
		}else {
		   timeStr =  minutes + "分" + remainingSeconds+"秒";
		}
		return timeStr;
	}
