Create a controller class, "PrintSequence" that will generate a view according to the descriptions provided in each methods. Then, in your newly created controller create 3 different methods, namely: BoxedFrame - Accepts 2 arguments - The segments that refers to your arguments should only accept numbers. Arguments: 1 - Row Size 2 - Column Size

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. Quit
The Contact class implements the Comparable interface and thereforeprovides a definition of the compareTo method. In this case, the contacts aresorted by last name; if two contacts have the same last name, their first namesare used.
Implement a test client that enables the user to specify the key and value fields in each query, along with a ST client FullLookupCSV that creates an array of ST objects (one for each field).
Below I have a sample class written in java and have several methods. I have only written the skeleton code for sample. Implement a simple proxy design pattern using java so that clients should only have access to very basic methods, while administrators of the system should have access to all methods public class Student { private name; private ID; private Grade; public double getname () {} public string getID () {} public double calculateGrade() {} }
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…
There are still errors in the lexer and shank files. Please fix those errors and make sure there are no errors in any of the files at all. Attached is an image of the error on the lexer file.

Q1) Q1) Can you explain this code? using for what? using System.Collections;using System.Collections.Generic;using UnityEngine; public class HealthSpawn : MonoBehaviour { public GameObject health; public Transform spawnPoint; private float spawnTime = 50f; private float spawnNext = 100f; private float maxHeight = 3f; private float minHeight = -2f; private float timer; void Start () { timer = Time.time; } void Update () { float t = Time.time - timer; if (t >= spawnTime) { transform.position = new Vector3(spawnPoint.position.x, Random.Range(maxHeight, minHeight)); Quaternion spawnRotation = Quaternion.identity; Instantiate(health, transform.position, transform.rotation); spawnTime = Time.time + spawnNext; } }}
Answer the given question with a proper explanation and step-by-step solution. Write a method that takes in an array of Point2D objects, and then analyzes the dataset to find points that are close together. Be sure to review the Point2D API. In your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. For example, "The distance between (3,5) and (8,9) is 6.40312." The complete API for the Point2D ADT may be viewed at http://www.ime.usp.br/~pf/sedgewick-wayne/algs4/documentation/Point2D.htmlLinks to an external site.. Do not compare a point to itself! Try to write your program directly from the API - do not review the ADT's source code. (Don't worry too much about your answer compiling - focus on using an API from its documentation.) Your answer should include only the method you wrote, do not write a complete program.
Which of the following is an example of dynamic dispatch? A: Assume you have an interface Car. There are three classes that implement the Car interface: Accord, Civic, Charger. Each of these classes has their own drive() method. There is an object myCar of type Car. When you invoke the drive() method, by calling myCar.drive() the correct implementation of drive() is chosen at runtime based upon the concrete class of myCar. B: Assume you have a variable myVariable. You have a for loop. The first time through the loop you set myVariable to an int, the next time you set it as a double, the next time a String, and finally an int. Each iteration of the loop myVariable has the correct type. C: Assume you have a class call Computation. Your computation class has a static method called add(). This method has three different versions:add(int x, int y)add(float x, float y)add(double x, double y)When you run Computation.add(x,y) the correct version of the method is chosen at compile time based…
Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.
. For the TimeSpan class described below, add a compareTo method that takes another TimeSpan object as a parameter & returns: -1 if this TimeSpan is SMALLER than to the TimeSpan object passed in as a parameter 0 if both TimeSpans are the same 1 if this TimeSpan is GREATER than the TimeSpan object passed in as a parameter Add code, as needed, to allow the Collections class to sort the ArrayList of TimeSpan objects import java.util.*; public class TimeSpan implements { private int hours; private int minutes; public TimeSpan(int hours1, int minutes1) { hours = 0; minutes = 0; add(hours1, minutes1); } public void add(int hours1, int minutes1) { hours += hours1; minutes += minutes1; while (minutes > 60) { minutes -= 60; // convert 60 min --> 1 hour hours++; } } public void add(TimeSpan time) { add(time.hours, time.minutes); }…
Create a graphical system that will allow a user to add and removeemployees where each employee has an employee id (a six-digitnumber), an employee name, and years of service. Use the hashcodemethod of the Integer class as your hashing function, and use oneof the Java Collections API implementations of hashing.
