Java异常命名约定 [英] Java Exception Naming Conventions

问题描述

在Java中，使用非法（如 IllegalArgumentException ）与无效（如 javax.activity.InvalidActivityException ）？

In Java, is there a semantic difference between using "Illegal" (as in IllegalArgumentException) versus "Invalid" (as in javax.activity.InvalidActivityException)?

在作业过程中，编写 IllegalArgumentException 的子类来表示一系列输入字符变得有用这不能被标记，我想知道约定是否使用 InvalidTokenException 或 IllegalTokenException 。

During the course of an assignment it became useful to write a subclass of IllegalArgumentException to represent a series of input characters that cannot be tokenized, and I'm wondering whether convention says to use InvalidTokenException or IllegalTokenException.

到目前为止，我唯一的区别是， java.lang 似乎更喜欢非法，而code> javax。* prefersInvalid。但是，还有 java.security.InvalidParameterException ，它是 IllegalArgumentException 的子类。

The only difference I can find so far is that java.lang seems to prefer "Illegal" while javax.* prefers "Invalid". However, there is also java.security.InvalidParameterException which is a subclass of IllegalArgumentException.

推荐答案

您可以拥有API的合法使用，并且仍然具有无效数据;这是所有语义。

You can have legal usage of an API and still have invalid data; it is all semantics.
