属性是 Class 文件的重要组成部分。和常量池类似，属性也分为很多类型，在 Java 虚拟机规范中，属性可用 attribute_info 数据结构伪代码表示：
|
||
|
|
|
||
|
|
```
|
||
|
|
attribute_info{
|
||
|
|
|
||
|
|
//属性名称，指向常量池中 Utf8 常量项的索引
|
||
|
|
u2 attribute_name_index;
|
||
|
|
|
||
|
|
//该属性具体内容的长度，即下面 info 数组的长度
|
||
|
|
u4 attribute_length;
|
||
|
|
|
||
|
|
//属性具体内容
|
||
|
|
u1 info[attribute_length];
|
||
|
|
}
|
||
|
|
```
