}//*El codigo para los tres metodos es
public void parse(){

accept(Token.EOF, "extra symbols after logical end of program");
}private void accept(int expected, String errorMessage){

fatalError(errorMessage);
token = scanner.nextToken();

chario.putError(errorMessage);
throw new RuntimeException("Fatal error");
