日历上课时间月份不匹配

Calendar class time month not matching(日历上课时间月份不匹配)

问题描述

Calendar c = Calendar.getInstance();

System.out.println("Mili->>" + c.getTimeInMillis());

System.out.println("Month  ->>" + Calendar.MONTH);

虽然我得到了毫秒格式的正确时间，但月份显示为 2(三月??)为什么会这样?

Though I am getting correct time in millisec format, Month is showing as 2 (March??) Why so?

下面是输出

米利->>1434029840778

Mili->>1434029840778

月 ->>2

Month ->>2

推荐答案

你想要的是以下成语:c.get(Calendar.MONTH).

What you want is the following idiom: c.get(Calendar.MONTH).

Calendar.MONTH 本身只是一个内部常量，并且(希望)总是返回 2.

Calendar.MONTH per se is just an internal constant and will (hopefully) always return 2.

示例

// We're in June at the time of writing
// Months are 0-based so June == 5
Calendar c = Calendar.getInstance();
System.out.println(Calendar.MONTH);
System.out.println(c.get(Calendar.MONTH));

输出

2
5
