最常见的检查和未检查的Java异常？ [英] Most common checked and unchecked Java Exceptions?

问题描述

据我所知，没有办法找出一个方法抛出的异常，而不是逐一查找API文档。

由于这是没有选择的，我想扭转研究，并询问您在处理时遇到的最常见的异常和运行时异常： / p>

• Casting


• 数组


• Vector，ArrayList，HashMap等等


• IO（文件类，流，过滤器，...）


• 对象序列化


• 线程（wait（），sleep（）等）


• 或任何被认为是基本Java的东西

我意识到这可能是主观和无聊，但它是一个类测试，我真的不知道更好。

解决方案

假设以下是java.lang，除非另有指定：

• Casting ：ClassCastException


• 数组：ArrayIndexOutOfBoundsException，NullPointerException


• 集合：NullPointerException，ClassCastException你不是使用自动装箱，而是拧紧它）


• IO ：java.io.IOException，java.io.FileNotFoundException，java.io.EOFException


• 序列化：java.io.ObjectStreamException（AND ITS SUBCLASSES，我也是懒惰的枚举）


• 线程：InterruptedException，SecurityException，IllegalThreadStateException


• 所有情况下都可能有共同之处：NullPointerException，IllegalArgumentException






您可以很好地查看Java网站的软件包摘要页面。这是一个： http://java.sun.com/j2se/1.4.2/docs/api/java/io /package-summary.html




As far as I understand, there is no way to find out which exceptions a method throws without looking up the API docs one-by-one.

Since that is no option, I'd like to reverse the research and ask you which are the most common Exceptions and RuntimeExceptions you've come across when dealing with:

• Casting
• Arrays
• Vector, ArrayList, HashMap, etc.
• IO (File class, streams, filters, ...)
• Object Serialization
• Threads (wait(), sleep(), etc.)
• or anything else that is considered "basic Java"

I realize that this might be subjective and boring but it is for a class test and I really don't know better.

解决方案

Assume the below are java.lang unless I specify otherwise:

• Casting: ClassCastException
• Arrays: ArrayIndexOutOfBoundsException, NullPointerException
• Collections: NullPointerException, ClassCastException (if you're not using autoboxing and you screw it up)
• IO: java.io.IOException, java.io.FileNotFoundException, java.io.EOFException
• Serialization: java.io.ObjectStreamException (AND ITS SUBCLASSES, which I'm too lazy to enumerate)
• Threads: InterruptedException, SecurityException, IllegalThreadStateException
• Potentially common to all situations: NullPointerException, IllegalArgumentException

You would do well to look at Java site's Package Summary pages. Here's one: http://java.sun.com/j2se/1.4.2/docs/api/java/io/package-summary.html
