Program's possibilities:

• Create a database, reading information from the given files
• Set up connections between data alsa using files
• Find books, countries and languages by given retailer or book ID
• Find common books for two retailers
• Find all books from two retailers

---

Functionality

Main class is named Administration. At the moment, when we initialize an instance of Administration, all of 7 structures are initialized and linked from the files.

class Program {
    /**
     * All the structure are initialized and linked in constructor
     */
    Administration administration = new Administration();
}

5 methods for searching

• getBooksForPublishingRetailerID

class Program {
    /**
     * Browsing the publishingArtifacts arrayList, looking for all the books, inclusive books from arrayLists inside
     * editorialGroups and publishingBrands, if books is not in arrayList yet, adding it to the end of array
     *
     * @param publishingRetailerID - valid ID to find corresponding publishingRetailer in arrayList of publishingRetailers
     * @return ArrayList of Books from publishingRetailer with ID == publishingRetailedID
     */
    Book[] books = getBooksForPublishingRetailerID(retailedID);
}

• getLanguageForPublishingRetailerID

class Program {
    /**
     * Browsing the publishingArtifacts arrayList, looking for all the books, inclusive books from arrayLists inside
     * editorialGroups and publishingBrands, looking for languageID of each Book in this.languages arrayList and adding
     * to the end of the arrayList which will be returned
     *
     * @param publishingRetailerID - valid ID to find corresponding publishingRetailer in arrayList of publishingRetailers
     * @return ArrayList of Languages from publishingRetailer with ID == publishingRetailedID
     */
    Language[] languages = getLanguageForPublishingRetailerID(retailerID);
}

• getCountriesForBookID

class Program {
    /**
     * Browsing each publishingRetailer, if publishingArtifact arrayList contains Book with ID == bookID, method
     * checkBook return true, in this case all the countries from publishingRetailer.countries will be added to countries
     * arrayList, which will be returned
     *
     * @param bookID valid ID to find corresponding Book in publishingRetailers
     * @return Arraylist of countries
     */
    Contry[] countries = getCountriesForBookID(bookID);
}

• getCommonBooksForRetailersIDs

class Program {
    /**
     * Obtaining two arrayList, adding first to the HashSet
     * Browsing the second arrayList, if HashSet contains books, adding to the arrayList which will be returned
     * Complexity: O(n + m)
     *
     * @param retailerID1 Valid ID of the first retailer
     * @param retailerID2 Valid ID of the second retailer
     * @return ArrayList of common books between retailer with ID == retailerID1 and retailer with ID == retailerID2
     */
    Book[] books = getCommonBooksForRetailersIDs(retailerID1, retailerID2);
}

• getAllBooksForRetailersIDs

class Program {
    /**
     * Obtaining two arrayList, adding both arrays to the HashSet
     * Converting HashSet to the arrayList
     * Complexity: O(n + m)
     *
     * @param retailerID1 Valid ID of the first retailer
     * @param retailerID2 Valid ID of the second retailer
     * @return ArrayList of common books between retailer with ID == retailerID1 and retailer with ID == retailerID2
     */
    Book[] books = getAllBooksForRetailersIDs(retailerID1, retailerID2);
}
