The throw keyword is used to throw an exception that may be generated in a code block. Ex: if (some condition){ throw new CannotProcessFileException("InvalidFile"); } The throws keyword is used in method signatures to signify the fact that, this method would be throwing exceptions of the type specified if the code in the method happens to generate one. Ex: public String getNameFromDB(int id) throws SQLException {
