Answer
It requires the caller to handle or declare the exception.
When a method signature includes 'throws IOException', any caller must either handle this exception using a try-catch block or declare it in its own throws clause. This ensures the program remains robust by forcing explicit exception management. For example, 'readData() throws IOException' means the calling method needs to consider IO failures.
