java 时间类calendar的小问题

import java.util.*;
<br>public class Test{
<br>public static void main(String args[]){
<br> Calendar c=Calendar.getInstance();
<br> c.set(Calendar.MONTH,0);
<br> System.out.println(c.get(Calendar.MONTH));
<br>
<br> c.set(Calendar.MONTH,1);
<br> System.out.println(c.get(Calendar.MONTH));
<br>}
<br>
<br>}
<br>我得到的结果是：
<br>D:test&gt;javac *.java
<br>
<br>D:test&gt;java Test
<br>0
<br>2
<br>
<br>奇怪：为什么不是0和1呢？
