Answer
It declares potential exceptions the method can pass to callers.
Including 'throws' in a method signature indicates that the method might incur certain exceptions, which must be managed by the caller. It's a contract with the caller to prepare for potential exceptions. For example, 'public void writeFile() throws IOException' signals that file I/O problems may arise.
