Kotlin-引发自定义异常 [英] Kotlin - Throw Custom Exception

问题描述

如何在Kotlin中引发自定义异常?我真的没有从文档中得到太多……

How can I throw a custom exception in Kotlin? I didn't really get that much off the docs...

在文档中，它描述了每个异常所需的内容，但是我如何实现它呢?

In the docs, it gets described what each exception needs, but how exactly do I implement it?

推荐答案

要记住的一件事:如果您使用的是IntelliJ IDE，只需复制/粘贴Java代码即可将其转换为Kotlin.

One thing to keep in mind: if you are using the IntelliJ IDE, just a simple copy/paste of Java code can convert it to Kotlin.

现在问您的问题.如果要创建自定义Exception，只需扩展Exception类，如:

Coming to your question, now. If you want to create a custom Exception, just extend Exception class like:

class TestException(message:String): Exception(message)

并像这样扔它:

throw TestException("Hey, I am testing it")
