如果检测到不良的构造树，将抛出什么异常？

[英]What exception to throw if a bad constructed tree is detected?

原文 2014-03-05 12:08:19 2 1 java/ tree

On a tree class I wrote I detect if the tree was constructed in such a way that there is a closed path from a node to itself (in which case it is a graph more than a tree) 在我写的一棵树类上，我检测到树的构造方式是否使得从节点到其自身的闭合路径（在这种情况下，它是图而不是树）

What kind of exception is advised to throw in such cases? 在这种情况下，建议抛出哪种异常？

1 个解决方案

If the exception is due to a wrong parameter passed to a specific method, IllegalArgumentException . 如果异常是由于将错误的参数传递给特定方法IllegalArgumentException而导致的。

If it is due to a series of operations that bring the tree to an invalid state: IllegalStateException . 如果是由于一系列使树进入无效状态的操作引起的： IllegalStateException 。
