Hi I am practising Java Programming. There is an error on line 153 saying 'invalid method declaration; return type required'. What can I do to avoid this error? I will attach a screenshot of my code below.

153 154 public Accomodation (String accomodationType, int rate) { 155 this . accomodationType = accomodationType; 156 this . rate = rate; 157 158 159 public Accomodation searchAccomodationsByAccomodationNo ( int accomodationNo) { 160 for (Accomodation r: accomodations) { 161 if (accomodationNo = r. getAccomodationNo() ) { 162 return r; 163 -D 164 return null; 165 166 @ 167 public double calculateTotalCost(TravelPackage b, Accomodation.
