- Write Program Java language Create an Animal class and an arraylist from that class you created. Then, add objects to that arraylist and print the elements?Design and implement a Java class named Book with two data members: title and price. The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well. Take screenshots of your tests and submit them with your Java code (not the whole project)Are there other predefined Java classes that are implemented with an array besides ArrayList class in Java?
- To do in Java I just need an example, you can fill all classes and array list or whatever it is with basic info that can show how to do this correctly.Java ArrayLists can only be filled with reference type data, so you cannot fill them with primitive type data. How can you work around this with integers? (How can you have an ArrayList filled with integers?)Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…

- A programmer is designing a program to catalog all books in a library. He plans to have a Book class that stores features of each book: author, title, isOnShelf, and so on, with operations like getAuthor, getTitle, getShelf Info, and set Shelf Info. Another class, LibraryList, will store an array of Book objects. The LibraryList class will include operations such as listAll Books, addBook, removeBook, and searchForBook. The programmer plans to implement and test the Book class first, before implementing the LibraryList class. The program- mer's plan to write the Book class first is an example of (A) top-down development. (B) bottom-up development. (C) procedural abstraction. (D) information hiding. (E) a driver program.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. Method named search Title to search books based on book title, this method should be able to accept a user string and search if a book with the title is in the added book list Method named searchAuthor to search books based on book title, this method…URGENtt!! You are asked to write a java class named "Kume". The UML class diagram of the Kume class is as follows. 3 The elements in the set are kept in an ArrayList. The constructor of the class takes an array of int and adds the elements of this array to the ArrayList named al. The add() method adds an integer it takes as a parameter to the get element. The delete() method deletes an Integer object that it takes as a parameter from the get element, returns true if it can be deleted, otherwise false. The print() function prints the elements of the set to the console. The compareTo() method is inherited from the Object class and is suppressed, and compares the get element of the Set object, which it takes as a parameter, with the retrieve element of the current set object in terms of content (the order of the elements is not important). It returns 1 if both sets contain the same elements, 0 otherwise. Below is a test code that creates two objects from the Kume class and performs…
