B.3 10 Points tinyBook.put("book', "A set of pages."); tinyBook.put("book', To arrange something on a particular date. tinyBook.put("bookable', "Can be ordered. ); tinyBook.put("bookbinder, "A person who fastens the pages of books. tinyBook.putf"bookcase', "A piece of furniture with shelves."); After these 5 lines execute, how the contents of tinyBook are different if we use the Oracle approach vs. the Google Guava approach? Please explain in detail.

Answer 1

Oracle Approach:

Using Oracle approach, if the given 5 lines are executed, then the result will be a hashmap with 4 keys {book, bookable, bookbinder, bookcase } with their values as {To arrange something on a particular date., Can be ordered., A person who fastens the pages of books., A piece of furniture with shelves. } i.e,

when the first line is executed a key "book" with value "A set of pages." will be created.

Then when the second line is executed, the key "book" will be replaced with the value "To arrange something on a particular date."

Google Guava Approach:

Using Google Guava approach, if the given 5 lines are executed, then the result will be a multimap with 4 keys {book, bookable, bookbinder, bookcase } with their values as {{A set of pages., To arrange something on a particular date.}, Can be ordered., A person who fastens the pages of books., A piece of furniture with shelves. } i.e,

when the first line is executed a key "book" with value "A set of pages." will be created.

Then when the second line is executed, the key "book" will be added with another value "To arrange something on a particular date."
