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

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

public class Example {
    public static void main(String[] args) {
        try {
            // some code that throws IOException
        } catch (IOException e) {
            IOExceptionList exceptionList = new IOExceptionList();
            exceptionList.add(e);
            // some code that throws another IOException
        } catch (IOException e) {
            exceptionList.add(e);
            // some code that throws a third IOException
        } catch (IOException e) {
            exceptionList.add(e);
            exceptionList.throwIfExceptions();
        }
    }
}

In this example, the try block contains some code that throws an IOException. The exception is caught and added to an IOExceptionList object. The process is repeated for other two exceptions. Finally, the throwIfExceptions() method is called on the IOExceptionList object, which will throw the first exception in the list if any exception has been added to the list.

Note: IOExceptionList is a class that is used to hold a list of IOExceptions. It is not present in org.apache.commons.io package and it is not part of any official release of Apache Commons IO.
