- Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class; these two classes will need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java.Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A,B,C,D,E" is correct. Each question has one correct answer. Thank you.

- Java - Encapsulation A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0, 0), the bottom right corner of the console is point (MAX, MAX) and given two points (all “x” and “y” coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class Point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the samplearea() - computes and returns the area of a given rectangleperimeter() - computes and returns the perimeter of a given rectanglecenterPoint() - computes and returns the center point…Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. Create array of countries called Arab of 22 countries. Write a function fill that fills the array Arab Write a method that finds the city that has the max area in a country Write a method that sorts the cities in a country from the largest to the smallest area Write a function that returns array of countries of the same area of Arab Write a function that compares between two countries. It returns true if country1 area greater than country2 area. Write a function to move a city from one country to another.See ERROR in Java file 2: Java file 1: import java.util.Random;import java.util.Scanner; public class Account {// Declare the variablesprivate String customerName;private String accountNumber;private double balance;private int type;private static int numObjects;// constructorpublic Account(String customerName, double balance, int type) { this.customerName = customerName;this.balance = balance;this.type = type;setaccountNumber(); // set account number functionnumObjects += 1;}private void setaccountNumber() // definition of set account number{Random rand = new Random();accountNumber = customerName.substring(0, 3).toUpperCase();accountNumber += type;accountNumber += "#";accountNumber += (rand.nextInt(100) + 100);}// function to makedepositvoid makeDeposit(double amount){if (amount > 0){balance += amount;}}// function for withdrawboolean makeWithdrawal(double amount) {if (amount < balance)balance -= amount;elsereturn false;return true;}public String toString(){return accountNumber +…

Create a class publication that stores the title (a string) and price(type float) of a publication. From this class derive 2 classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of theses 3 classes should have a getdata() method to get its data from the user at the keyboard, and a putdata() function to display its data. Suppose you want to add the date of publication for both books and tapes. From the publication class, derive a new class called publication2 that includes this data member. Then change book and tape so ther are derived from publication2 instead of publication. Make all the necessary changes in member functions so the user can input and output dates along with the other data. For the dates, you can use the bulit-in date function which stores a date as 3 ints, for months, day and year. Write a…Computer Science I need the code for this in Alice programming Faery Magic Create a world that has at least 5 different objects from the Furniture Gallery and one Faery from the Fantasy/Faeries Gallery. The Faery has the power to make an object disappear. Everything that the faery touches disappear from the scene. Create an interactive game where the user can click one object at a time from the scene; then, the faery faces that object and moves toward it. Write a recursive method named CheckDistance, that checks whether the faery is very close to the object clicked by the user. If it is, the faery bends over to touch the object. After the faery touches the object, the object disappears (this is the base case of the recursion). If the faery is not yet close enough to the object to be able to touch it, the faery moves a small distance forward and the CheckDistance method is recursively called (this is the recursive case of the recursion). Include instructions for the game that appears…
