- JAVA: Create generics class for validation and printing for the parking garage projectContainers that support random-access iterators can be used with most but not all Standard Library algorithms. What is the exception?Exercise 2. Create a Book class where: Each book contains the following information: book title book Author name, barcode (as fong integers), and book topic. o Implement an appropriate constructor(s) and all necessary get/set methods. Test Book class: o Create diffcrent book objects (at least 5 hooks) and store them in a LinkedList sorted by book barcode value Generate a unique random integer value for the barcode. Iterate through the LinkedList and print out the books' details O Create a second LinkedList object containing a copy of the above LinkedList, but in reverse order.
- Write a java class Library for implementing a library application which accepts books into its list and user should be able to search books based on a book title or the Author. The books should be added to an ArrayList. Write the Main class with main function in it to display a menu to opt whether to add books, list books and search books. Use a constructor of Library class to add books. Use a method named searchTitle and searchAuthor in Library class to search the books. 1) Define class Library with required instance variable ArrayList for adding books 2) The Library class should have one constructor and three methods to do the below functions The Constructor needs to add books Method displayBook to List all the books in the library.

Create an instance method called count that takes a single parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how many times each word occurs in dataFile. The counts should be stored in an instance variable called wordCounter. Create an instance method called write that takes a single parameter called outputFile (representing the path to a text file) and writes the contents of wordCounter to the file pointed to by outputFile. The output file should be overwritten if it already exists, and created if it does not exist. Create a separate class called Application that contains a main method which illustrates the use of DuplicateCounter by calling both the remove and write methods. Your input file must be called problem2.txt and your output file must be called unique_word_counts.txUsing c++ I would like to implement a queue as a class with a linked list.
