(Enhanced Employee Class) Modify class Employee inFigs. 12.9–12.10 by adding a private utility function calledisValidSocialSecurityNumber . This member function shouldvalidate the format of a social security number (e.g., ###-##-#### , where # is a digit). If the format is valid, return true ;otherwise return false .

(do not use any of the respective native JS methods to implement your solutions(javascrpt)JavaScript syntax, functions, and higher-order functions, and to better understand JavaScript and Array methods.do not copy from chegg)   reduce()   Without using the native “Array.prototype.reduce” method of JavaScript, compose a function titled “myReduce” that will take in an array of elements and executes a callback function (provided by you) on each of those elements.   includes()   Without using the native “Array.prototype.includes” method of JavaScript, compose a function titled “myIncludes” that will take in an array of elements and indicates whether or not a target element is contained within the input array. This returns a boolean.

(Java) Q4 explain the answers to the below questions using step-by-step explanation.   4. Write the bubbleSort method for an array of integers The name of the method is bubbleSort It takes in one parameter - an array of integers It sorts the array according to the bubble sort algorithm It returns nothing

(The Rectangle class) Following the example of the Circle class in Section 8.2,design a class named Rectangle to represent a rectangle. The class contains:■ Two double data fields named width and height that specify the width andheight of the rectangle. The default values are 1 for both width and height.■ A no-arg constructor that creates a default rectangle.■ A constructor that creates a rectangle with the specified width and height.■ A method named getArea() that returns the area of this rectangle.■ A method named getPerimeter() that returns the perimeter.Draw the UML diagram for the class and then implement the class. Write a testprogram that creates two Rectangle objects—one with width 4 and height 40and the other with width 3.5 and height 35.9. Display the width, height, area,and perimeter of each rectangle in this order.

(Java) Open up Eclipse and create a new class called ArrayListPractice.java Next, copy and paste the below program into your file and run the code. Your job is to take the given code, remove all the arrays and replace them with the identical ArrayLists. There should be no arrays in your program. You will need to call the ArrayList methods as defined in the lesson notes above. Note that you will not be able to do method overloading with ArrayLists so you should assign different names to your methods. Once you have made the changes, you should get identical output as the given version of the program. Submit your program when you are finished. /** * @author * CIS 36B * Activity 5.2 */import java.util.ArrayList;import java.util.Scanner;public class ArrayListPractice {    public static void main(String[] args) {                int scores[] = {95, 96, 97, 98, 99};        System.out.println("Integer exam scores:");        print(scores);        System.out.println();…

[In c#] Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operator

(Geometry: MyRectangle2D class)  Define the  MyRectangle2D class that contains:  Two double data fields named x and y that specify the center of the rectangle with getter and setter methods. (Assume the rectangle sides are parallel to the x- or y-axis.) The data fields width and height with getter and setter methods. A no-arg constructor that creates a default rectangle with (0, 0) for (x, y) and 1 for both width and height. A Constructor that creates a rectangle with the specified x, y, width, and height. A method getArea() that returns the area of the rectangle. A method getPerimeter() that returns the perimeter of the rectangle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this rectangle (see Figure 10.24a ). A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle (see Figure 10.24b ). A method overlaps(MyRectangle2D r) that returns true if the specified rectangle overlaps with this…

(Recursive Binary Search) Write a recursive method RecursiveBinarySearch to perform abinary search of the array. The method should receive the search key, starting index, endingindex and array A as arguments. If the search key is found, return its index in the array. If thesearch key is not found, return -1.int RecursiveBinarySearch(int search, int start, int end, int[] A)
