You are given a list of projects and a list of dependencies (which is a list of pairs of
projects, where the second project is dependent on the first project). All of a project's dependencies
must be built before the project is. Find a build order that will allow the projects to be built. If there
is no valid build order, return an error.
EXAMPLE
Input:
projects: a, b, c, d, e, f
dependencies: (a, d), (f, b), (b, d), (f, a), (d, c)

Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…Create functional tests where arguments are given, use a parameterized test. testSimpleInit(size): the first constructor works as expected. getTiles shows suitable values. The edges of the board (the smallest and biggest conceivable values) are accessible and contain the values that they have to (BASE_TILE_SCORE). testCustomInit(x, y, expected): the second constructor works as expected. On positions where values smaller than three were passed, the board contains the value BASE_TILE_SCORE. If you pass an array to the constructor and later modify a value in it, the respective tile retains the originally passed value. If you modify an element in the return value of getTiles(), and get the value of the respective tile again, this newly received content has to be the originally set value. testMoves(): take four or five steps and check that the board’s contents are changed just right. Include a step that tries to move to the x coordinate Integer.MIN_VALUE and another one that moves to…
- Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…A readinglist is a doubly linked list in which each element of the list is a book. So, you must make sure that Books are linked with the previous prev and next element. A readinglist is unsorted by default or sorted (according to title) in different context. Please pay attention to the task description below. Refer to the relevance classes for more detail information. Implement the add_book_sorted method of the ReadingList class. Assume the readinglist is sorted by title, the add_book_sorted method takes an argument new_book (a book object), it adds the new_book to the readinglist such that the readinglist remain sorted by title. For example, if the readinglist contain the following 3 books: Title: Artificial Intelligence Applications Author: Cassie Ng Published Year: 2000 Title: Python 3 Author: Jack Chan Published Year: 2016 Title: Zoo Author: Cassie Chun Published Year: 2000 If we add another book (titled "Chinese History"; author "Qin Yuan"; and published year 1989) to the…This assignment is supposed to represent a group of students in a course. A group of students in a course will be assigned an assignment and produce a collection of assignment results. The results will be used to figure out grade statistics. The grade they receive for their work on the assignment is entirely dependant on the student's energy level. If the student works on many assignments without sleeping their grade will suffer. You will implement four classes (Assignment, AssignmentResult, Student, and Course), they will depend on each other in the order they are listed. Hint: Work on the methods in the order they are found in the documentation below, implement the getter and setter methods before the more complicated methods. Work on the Assignment class, AssignmentResult class, Student class and Course class in that order. Make sure you don't name your class variables the same name as you class's methods. In other words if you have method named id you cannot have a class…
