- In Java!!!!! Design and implement an application that simulates the customers waiting in line at a bank. Use a queue data structure to represent the line. As customers arrive at the bank, customer objects are put in the rear of the queue with an enqueue operation. When the teller is ready to service another customer, the customer object is removed from the front of the queue with a dequeue operation. Randomly determine when new customers arrive at the bank and when current customers are finished at the teller window. Print a message each time an operation occurs during the simulation.ArrayAndArrayListTest.java package arrayandarraylist; import static org.junit.jupiter.api.Assertions.*; import java.util.ArrayList; import org.junit.jupiter.api.BeforeEach; import org.junit.jupiter.api.Test; class ArrayAndArrayListTest { // declare myArrayAndArrayList which is the object for testing ArrayAndArrayList myArrayAndArrayList; @BeforeEach void setUp() throws Exception { // initialize myArrayAndArrayList for testing this.myArrayAndArrayList = new ArrayAndArrayList(); } /** * Test howMany method in ArrayAndArrayList. */ @Test void testHowMany() { // element in the array int[] array = {1, 3, 5, 7, 9, 1, 2, 3, 4, 5}; assertEquals(2, this.myArrayAndArrayList.howMany(array, 1)); // TODO write at least 3 additional test cases } /** * Test findMax method in ArrayAndArrayList. */ @Test void testFindMax() { // findMax in an nonEmpty array int[] array = {1, 3, 5, 7, 9, 1, 2, 3, 4, 5}; assertEquals(9, this.myArrayAndArrayList.findMax(array)); // TODO write at…Assume there exists a website that sells tools that includes a search feature. We want to implement a feature that returns the total price of all the items that match a search, that is, the sum of the prices of everythingthat matched the search called searchTotal.Write a controller for the website that implements the method searchTotal(). The searchTotal() method accepts a single argument: the string to match. It will use the string to query the product database to find the matching entries. searchTotal() will sum the prices of all the returned items of the search.Use model->search () to query the database; it returns the matches found with the search term. Assume that the table schema includes a Price column.
- In Java, Create Movie class, which has private fields for title, director, rating. It has a constructor to initialize these fields and a toString method for printing movie details. There is also a getRating method to retrieve the movie rating. Create Rating Comparator class which implements the Comparator interface for comparing movies based on their ratings. Create DemoMovies Class. Initialize necessary data structures like LinkedList, TreeMap for rating as key and Movie from Movie class as value, TreeSet, and ProtiyQueue. Use a loop to take user input for movie detailsuntil the user enters 'WWW' as the movie title.Inside the loop, for each movie, create a Movie object, add it to various data structures that is title, director and rating based on the constructor. Add the Movie object to the LinkedList. Add the rating and the object to the TreeMap.Add the rating to the TreeSet.Add the Movie object to the Priority Queue.Display the entered movies. Sort and display Movies by rate by…Create a SameItem Interface: The SameItem interface will be a generic interface.SameItem will have a single method: isSameAs(T) that returns a booleanMyFileReaderTest.java import static org.junit.Assert.assertEquals; import java.util.ArrayList; import org.junit.jupiter.api.BeforeEach; import org.junit.jupiter.api.Test; public class MyFileReaderTest { MyFileReader myFileReader1; MyFileReader myFileReader2; MyFileReader myFileReader3; MyFileReader myFileReader4; MyFileReader myFileReader5; @BeforeEach void setUp () { this.myFileReader1 =new MyFileReader("info.txt"); // original info.txt file this.myFileReader2 =new MyFileReader("test2.txt"); // file with multiple words per line this.myFileReader3 =new MyFileReader("test3.txt"); // similar to info.txt file but with leading and trailing whitespace this.myFileReader4 =new MyFileReader("test4.txt"); // similar to info.txt file but with different info this.myFileReader5 =new MyFileReader("test5.txt"); // similar to info.txt file but with blank lines in between lines with information } @Test publicvoid testGetCleanContent(MyFileReader myFileReader2, final MyFileReader…
- The StateManager Interface is a generic interface which has two methods changeState (boolean : status). This method is used to change the status of InvoiceItem and PrescriptionItem. The possible status for InvoiceItem can be (Available – true or Unavailable - false), whereas PrescriptionItem has status (Recommended-true or Prohibited – false) passed to the method as an argument. The reset () method sets the default value for both InvoiceItem and PrescriptionItem. The Item class is self-explanatory. It implements the StateManager interface, and has toString method which prints the information in the following format. "Item Name: <<name>> (<<id>>)” e.g. Item Name: Panadol (223) Two classes PrescriptionItem and InvoiceItem are inherited from Item class representing the items that can be sold with doctor’s prescription and without prescription respectively with following functionalities: The constructors of PrescriptionItem and InvoiceItem initialize fields to…Create a Java Program in NetBeans for Builders Warehouse. The program must consist of a class called Materials to handle the details of the materials. The program should read the materials details from the material.txt file then use a LinkedList to store the material details. Then finally the products stored in the LinkedList must be displayed to the screen as shown in Figure 2 below:Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.
- Say we are about to build an ArrayList. Your ArrayList should guarantee that the array capacity is at most four times the number of elements. What would you like to do to maintain such a limit on the capacity? What is the benefit of using iterators? Can you describe your first experience of GUIs? And could you describe what is the advantage of using GUIs over Command-Line Interface (CLI) operations?The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. 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…Computer Science Write the client code to show how you make use of the LegacyCircle class with your new design.
