import java.util.*;
public class test2 {
    public static void main(String[] args) {
        Calendar c = Calendar.getInstance();
        int index1 = c.get(Calendar.MONTH);
        System.out.println("现在是今年的第"+index1+1+"个月");
        
        System.out.println("现在是今年的第"+Calendar.MONTH+1+"个月");//上面的是标准,该行是错的,
        //我的问题是为什么直接用Calendar.MONTH是错的,这个Calendar类的get(~)方法内部是怎么实现
        //的呀.实在想不明白.请大神别复制了源代码然后不给解释呐,我看不懂才来问的.大神9我
    }
}

class A {
    public static final int MONTH = 0;

    public static int get(int field) {
        return 100;
    }
}

------解决方案--------------------
还是先看一下源码
Java code

 // Field descriptor #98 I
  public static final int ERA = 0;
  
  // Field descriptor #98 I
  public static final int YEAR = 1;
  
  // Field descriptor #98 I
  public static final int MONTH = 2;
  
  // Field descriptor #98 I
  public static final int WEEK_OF_YEAR = 3;
  
  // Field descriptor #98 I
  public static final int WEEK_OF_MONTH = 4;
  
  // Field descriptor #98 I
  public static final int DATE = 5;
