JAVA实现秒转换为时分秒格式

查询到的方法：

 public static String secToTime(int seconds) {
        int hour = seconds / 3600;
        int minute = (seconds - hour * 3600) / 60;
        int second = (seconds - hour * 3600 - minute * 60);
 
        StringBuffer sb = new StringBuffer();
        if (hour > 0) {
            sb.append(hour + "小时");
        }
        if (minute > 0) {
            sb.append(minute + "分");
        }
        if (second > 0) {
            sb.append(second + "秒");
        }
        if (second == 0) {
            sb.append("<1秒");
        }
        return sb.toString();
    }

实际在项目中使用的：

 public ItooResult selectKeyByTimeClass(Date createTime, Date endTime, String className) {
        List keyModels = KeyDao.selectKeyByTimeClass(createTime, endTime, className);
        if (keyModels == null || keyModels.size() == 0) {
            return new ItooResult(ItooResult.FAIL, "查询失败");
        }
		//将time类型的练习时长转换为*分*秒的字符串类型
        for (KeyModel keyModel : keyModels) {
           Integer setTime = keyModel.getSetTime();
           Integer minute=setTime/60;
           Integer second=(setTime-minute*60);
            StringBuffer sb = new StringBuffer();
            if (minute > 0) {
                sb.append(minute + "分");
            }
            if (second > 0) {
                sb.append(second + "秒");
            }
            String strDate = sb.toString();
            keyModel.setStrTime(strDate);

        }
        return new ItooResult(ItooResult.SUCCESS, "查询成功", keyModels);
    }
