日历类时间月不匹配 [英] Calendar class time month not matching

问题描述

 日历c = Calendar.getInstance（）; 
 
 System.out.println（Mili->>+ c.getTimeInMillis（））; 
 
 System.out.println（Month  - >>+ Calendar.MONTH）; 
  

虽然我以毫秒格式获得正确的时间，但月份显示为2

Mili - >> 1434029840778

月 - >> 2

解决方案

你想要的是以下成语： 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 。

> //我们在六月的时候写
//月份是0，因此June == 5
Calendar c = Calendar.getInstance（）;
System.out.println（Calendar.MONTH）;
System.out.println（c.get（Calendar.MONTH））;


输出

  2 
 5

Calendar c = Calendar.getInstance();

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

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

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

Below is output

Mili->>1434029840778

Month ->>2

解决方案

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

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

Example

// 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));

Output

2
5
