- Java Program Consider a class Student that has an attribute age and a method getAge(): StudentList is a class representing a linkedlist of students. Write sumListAge_lterative......), a method that computes and returns the sum of the ages of all students in the list using the iterative way. Parameters of the method should be specified accordinglyJava Programming Define a class CollectionBooks. This class has a data member list of type Book using the ArrayList collection. Define method add. This method add the any object to list. Define printAll. This method display all the added object in the list. Define printAll. This method display all the added object in the list. · Define int count. This method returns the number of objects added in the list. Define Book search(Object e). This method returns the object being search if not found return null. Define void remove(int index). This method remove the object in a list Add a main method with the following menu:1 – Add 2 – Count 3 – Print4 – Search 5 – Delete 6 - ExitComputer Science Write a program in the Java language that includes: 1. A class for books, taking into account the encapsulation and getter, setter. 2. Entering books by the user using Scanner 3. LinkedList class for: (Adding a new book - Inserting a book- Searching for a book using the ISBN Number - Viewing all books,delete book). 4. Serial number increases automatically with each book that is entered. 5. Printing the names of books is as follows: Serial - ISBN - Name - PubYear - Price - Notes. 6-Design a main menu that includes: • Add Book • Insert Book • Delete Book • Search . Display . Exit
- Tour.java Create a Tour data type that represents the sequence of points visited in a TSP tour. Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…Exercise 2: Create a Book class; where: lo Each book contains the following information: book title, book Author name, barcode (as long integers) and book topic. 6 Implement an appropriate constructor(s) and all necessary get/set methods. Test Book class: lo Create different book objects (at least 5 books) and store them in a LinkedList sorted by book barcode value. Generate a unique random integer value for the barcode. O 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 orderJava Programming Class Car Attributes (all private): vin: String (5 digits) make: String model: String year: int price: double Methods: Parameterized constructor for initializing a new Car instance Getters for all attributes toString method to display a Car's attributes Executable Class Create an array of at least ten Car objects. Be sure to use many with identical last years and different prices. Create an ArrayList from the array. Shuffle the ArrayList. Sort the ArrayList first by year and then by price. See page 790-791. Using the forEach method and a lambda expression, print all cars sorted as above. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the entire LinkedList but without generating any output. Then iterate backwards through the LinkedList to print the cars data.
- java method : Write a method called prioritizeQueue to give priority for vaccination for elderly persons. The method is to be in a class called VaccinationQueue and has two parameters q1 and q2 type ArrayQueue. The q1 and q2 data are of type Integer. Assume that initially q1 is not empty and q2 is empty. The method will insert from q1 those elements towards the beginning of the queue (front) q2 whose data is greater than or equal to 45 and will insert those elements whose data is less than 45 and greater than or equal to 18 towards the end (rear) of q2. Any data item less than 18 of q1 will not be inserted in q2. It returns the number of elements added to q2. Class ArrayQueue and all its methods including iterator are available for use. You can also create temporary queues. You are not allowed to use arrays or any other data structure. Example: Before method call: front rear q1: 14 25 50 70 35 45 19 10 21…ODDITERATOR AND ODDITERABLE OddIterator is an Iterator of type Integer OddIterable is an Iterable of type Integer In OddIterator, the elements returned by the Iterator are the odd numbers in a given list. Since OddIterator is an Iterator, we will want to include the following methods in the class: o +OddIterator(Iterable) A constructor which is passed in the Integer iterable list to iterate over. Tip: note that the list is really an Iterable of type Integer. The private member iter of this class is assigned as an iterator to the passed in Iterable o +hasNext() method is required by the Iterator interface. This method returns true if there are more elements to be returned by the iterator (i.e there are still odd numbers in the list). Or the method returns false when there are no more odd numbers left in the list. o +next() method is required by the Iterator interface. This method returns the next element from the list that is an odd number. Tip: do not forget to throw a…class Solution(object): def longestCommonPrefix(self, strs): result ="" for i in strs[0]: for j in strs[1]: for k in strs[2]: if i == j and i == k: result+=i if len(result) >0: return result else: return result IndexError: list index out of range for j in strs[1]: Line 5 in longestCommonPrefix (Solution.py) ret = Solution().longestCommonPrefix(param_1) Line 31 in _driver (Solution.py) _driver() Line 41 in <module> (Solution.py) can someone explain why this is wrong?
- Computer Science create a method +addToList(o:E):void that adds the object (o) to the ArrayList referenced by the instance variable list. create a method +removeFromBackOfList():E that removes the object at the back of the ArrayList and returns it.6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.a go-kart operator uses a linked list to store the data of go-kart customers. the following classes are used for this purpose
