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
