- 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.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. Add and remove tellers. Then control how efficient each teller is (when instantiating a new teller, there will be a parameter to control the relative speed of each teller. You will still use random values, but will multiply them them with some coefficient based on a given teller's "speed"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.
- Consider a scenario of Contacts Database, in which all information of user contacts will be stored. In the given scenario you have to implement your database of contacts using the Generic Arraylist you have created in Task 1. Steps to Follow:Step 1:In first step you have to create Contact class with the following attributes;● First Name● Last Name● Phone Number● Email AddressAdd mutator and accessor methods for all given attributesStep 2:You have to create a menu consisting of the following functionalities;1. Add a new contact2. Display all contacts3. Display specific contact 4. Delete a contact5. QuitImplement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.Implement LinkedListclass for this problema.Create an Employeeclass which will have details like EmployeeNo, EmployeeName and Address. You should pass value for EmployeeNo, EmployeeName and Addressthrough constructor.b.Create a method addInput( ) which will add employee details to LinkedList.c.Create method display( ) which should display all data from LinkedList using forward and reverse order using Iterator and ListIterator interfaces.d.Note:addInput( ) and display( ) should not be member functions of Employeeclass
- Write a program that uses an ArrayList of parameter type Contact to store a database of contacts. The Contact class should store the contact's first and last name, phone number, and email address. Add appropriate accessor and mutator methods. Your database program should present a menu that allows the user add a contact, display all contacts, search for a specific contact and display it, or search for a specific contact and give the user the option to delete it. The searches should find any contact where an instance variable contains a target search string. For example, if "elmore" is the search target then any contact where the first name, last name, phone number, or email address contains "elmore" should be returned for display or deletion. Use a "for each" loop to iterate through the ArrayList.Design and implement a service that simulates PHP loops. Each of the three loop variants should be encapsulated in an object. The service can be controlled via a parameter and execute three different simulations. The result is returned as JSON. The input is an array consisting of the letters $characters = [A-Z]. -The For loop should store all even letters in an array.-The Foreach loop simulation is to create a backward sorted array by For loop, i.e. [Z-A] .-The While loop should write all characters into an array until the desired character is found. Interface:-GET Parameter String: loopType ( possible values: REVERSE, EVEN, UNTIL )-GET parameter String: until (up to which character) Output:JSON Object: {loopName: <string>, result: <array> }Assignment Apex: Apply SOQL on Contact to get the Contacts for Account those we got from 1st SOQL: Add a new method: Name: getContactInformationForSpecificAccount Return Type: Map> args: List
- Description: In this project, you are required to make a java code to build a blockchain including multiple blocks. In each block, it contains a list of transactions, previous hash - the digital signature of the previous block, and the hash of the current block which is based on the list of transactions and the previous hash. If anyone would change anything with the previous block, the digital signature of the current block will change. When this changes, the digital signature of the next block will change. Detailed Requirements: 1. Define your block class which contains three private members and four public methods. a. Members: previousHash (int), transactions (String[]), and blockHash (int); b. Methods: i. Block( int previousHash, String[] transactions){} ii. getPreviousHash(){} iii. getTransaction(){} iv. getBlockHash(){} 2. Using ArrayList to design your Blockchain. 3. Your blockchain must contain genesis block and make it to be the first block. 4. You can add a block to the end of…Create an interactive system that allows a user to add and delete workers, with each employee having a six-digit employee id, a name, and years of service. As your hashing algorithm, use the Integer class's hashcode method and one of the Java Collections API hashing implementations.CustomIntegerArrayListTest.java package integerarraylist; import static org.junit.jupiter.api.Assertions.*; import java.util.ArrayList; import org.junit.jupiter.api.Test; class CustomIntegerArrayListTest { @Test void testGetArrayList() { //create a new empty CustomIntegerArrayList CustomIntegerArrayList arr1 = new CustomIntegerArrayList(); arr1.add(2); arr1.add(0, 5); arr1.add(1, 5); ArrayList<Integer> lst1 = new ArrayList<Integer>(); lst1.add(2); lst1.add(0, 5); lst1.add(1, 5); assertEquals(lst1, arr1.getArrayList()); ArrayList<Integer> arr4Elements = new ArrayList<Integer>(); arr4Elements.add(100); arr4Elements.add(200); arr4Elements.add(500); //create a new CustomIntegerArrayList with the elements in the given ArrayList CustomIntegerArrayList arr4 = new CustomIntegerArrayList(arr4Elements); ArrayList<Integer> lst4 = new ArrayList<Integer>(); lst4.add(100); lst4.add(200); lst4.add(500); assertEquals(lst4, arr4.getArrayList()); //…
