最大大小的java类/异常表 [英] maximum size of java class / exception table

问题描述

我想知道一个java类的最大大小是多少。如此处所示 http：// docs。 oracle.com/javase/specs/jvms/se5.0/html/ClassFile.doc.html#1546 在代码属性结构中，代码长度指定为4字节，因此它是一个大数字。我不明白的是，异常表的pc属性是2字节。

I was wondering what is the maximum size of a java class. As shown here http://docs.oracle.com/javase/specs/jvms/se5.0/html/ClassFile.doc.html#1546 in the Code attribute structure, code length is specified as 4-bytes, so it is a big number. What I did not understand is that the pc attributes of exception table are 2 bytes. How can it work if code length is more than 2-bytes but exception tables can only address the 2-bytes ?

推荐答案

code_length 项目的值必须

The value of the code_length item must be less than 65536.

因此，尽管它是一个4字节的值，它不能超过64k。

So although it is a 4 byte value, it must not exceed 64k.
