Answer
The 'throws' keyword in a method signature indicates potential exceptions the method might throw.
Including 'throws' in a method signature alerts callers of the method to handle the specified exceptions, either by catching them or declaring them in their own method signatures. For example, 'void readFile() throws IOException' means the caller must be prepared to handle an 'IOException'.
