Here's an example of how to use the TaggedIOException class from the Apache Commons IO library:

import java.io.IOException;
import org.apache.commons.io.TaggedIOException;

public class Example {
    public static void main(String[] args) {
        try {
            // some code that throws IOException
        } catch (IOException e) {
            throw new TaggedIOException(e, "tag1");
        }
    }
}

In this example, the try block contains some code that throws an IOException. The exception is caught and wrapped in a TaggedIOException object with a tag "tag1". The TaggedIOException class provides a way to add a tag to an IOException, so you can identify the source of the exception.

Additionally you can also access the tag using TaggedIOException.getTag() method and also the original exception using TaggedIOException.getCause() method.

Note: TaggedIOException is a class that is used to wrap IOExceptions and provide a tag to indicate where the exception occurred. It is not present in org.apache.commons.io package and it is not part of any official release of Apache Commons IO.
