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。
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
- 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"
- 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
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:
I realize that this might be subjective and boring but it is for a class test and I really don't know better.
Assume the below are java.lang unless I specify otherwise:
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
