What are the most commonly reused Java exception classes?

In favor of using standard exceptions

The most commonly reused Java exception classes are as follows:

1.java.io.IO异常
2.java.io.FileNotFoundException
3.java.io.UnsupportedEncodingException
4. java.lang.reflect.InvocationTargetException
5.java.security.NoSuchAlgorithmException
6.java.net.MalformedURLException
7.java.text.ParseException
8. java.net.URISyntaxException
9. java.util.concurrent.ExecutionException
10. java.net.UnknownHostException

None of the top 10 are the most commonly used ones shown in the book. But be aware that these are calculated per project, i.e. if a class is used in a project, it is only counted once, no matter how many methods in the project use it. So this is calculated by the number of items, but by the number of occurrences in the code.
