We can get a column? S value either by specifying the column index as an integer or the column name as a String object. I show both approaches in the code.
通过指定整数类型的列索引，或String对象类型的列名，就可以获得一个列的值。
A field such as ContactDatabase.N can be an aggregate composed of up to five parts, as follows, where the integer represents the index of the respective component part.
如ContactDatabase . n之类的字段可以是最多由5个部分组成的聚合，如下所示，其中整数表示各个组件部分的索引。
Any integer expression can be used as an index.
任意的一个整型表达式，都可以用来作为索引编号。
In this paper, we study the condition which makes the fundamental group of graph have every positive integer as the index of some normal subgroup.
本文主要研究图的基本群的正规子群的指数何时成为任意正整数的条件。
The reason for excluding 65535 is pragmatic: likely implementations will use a 2-byte integer to track both a local's index, as well as the total number of locals for a given method.
不包括65535的原因是实际的：实现很可能将使用2字节整数跟踪两个局部的索引以及给定方法的局部索引的总数。
An indexed header field starts with the '1' 1-bit pattern, followed by the index of the matching header field, represented as an integer with a 7-bit prefix.
