我如何检查更多我输入if ... else android

Question

这是我的代码。我想在早上，下午和晚上进行比较。我可以这样做吗？

private String interpretFT(int morninghour, int afternoonhour, int eveninghour)
    {
        if (morninghour > afternoonhour )
        {
            return "Time to exercise : Morning";
        }
        else if (afternoonhour > eveninghour)
        {
            return "Time to exercise : Afternoon";
        }
        else if (eveninghour > morninghour)
        {
            return "Time to exercise : Evening";
        }
        else
        {
            return "Please have the freetime to have some exercise";
        }
    }

Answer 1

你想用这个做什么？ 如果你想从当前时间获得字符串：

  private String interpretFT(int morningHour, int afternoonHour, int eveningHour, int currentHour){

    String result = "";

    if (currentHour => morninghour && currentHour < afternoonhour )
    {
        result = "Time to exercise : Morning";
    }
    if (currentHour => afternoonhour && currentHour < eveninghour)
    {
        result = "Time to exercise : Afternoon";
    }
    if (currentHour => eveninghour && currentHour < morninghour)
    {
        result = "Time to exercise : Evening";
    }
    else
    {
        result = "Please have the freetime to have some exercise";
    }

return result;
}

比较我建议使用三元运算符，例如：

private String interpretFT(int morninghour, int afternoonhour, int eveninghour) {
        return ((morninghour > afternoonhour) ? "Time to exercise : Morning" :
                (afternoonhour > eveninghour) ? "Time to exercise : Afternoon" :
                        (eveninghour > morninghour) ? "Time to exercise : Evening" :
                                "Please have the freetime to have some exercise");

    }
