java.io Exceptions:

The classes in java.io throw a variety of exceptions. Some classes which work along with I/O are good candidates to throw recoverable exceptions. For instance, activities like as opening files or writing to files are likely to fail from time to time. The classes of the java.io package do not throw errors at all.
