Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
2. Write a class ArrayClass, where the main method asks the user to enter the four
num bers. Create a method printArray that prints the array whenever required (use
Acrav.toString method). Make the program run as shown in the Sample Run below.
Green is user input.
Use Attax.sort, Attach.bianrySearch. Attaveauals
Sample Run
List1, Enter four num bers: 2 33 2
List2, Enter four num bers: 6 25 4
List3, Enter four num bers: 52 46
Your original Listi: [2, 3, 3, 2]
Your original List2: [6, 2, 5, 4]
Your original List3: [5, 2, 4, 6]
Sorted Listi is: [2, 2, 3, 3]
Enter a number from the sorted List1 to search for: 3
Value 3 is in index 2 (or position 3)
List that are the same when sorted: [2, 4, 5, 6]
Write a method that takes two arrays as parameters. It should
return a new array where each position has the sum of the two
corresponding positions in the two incoming arrays. The returned
array should be as long as the longer of the two passed in arrays.
