Based on the information in the screenshots, please answer the following question below. The language used is Java and please provide the code for it with the explanation. Create a testing class named “PlanTest”. Under this class, there needs to be another static method besides the main method: You will need to create a static method named “prerequisiteGenerator” under “PlanTest”, which return a random 2D array containing prerequisite pairs (e.g., {{1, 3}, {2, 3}, {4, 2}}). The value range of a random integer is [0, 10] (inclusive). This method will accept an integer parameter, which specifies the length of the returned array: int[][] pre = prerequisiteGenerator(3); // possibly {{1, 3}, {2, 3}, {4, 2}} Under the main method, you will need to use prerequisiteGenerator to generate random prerequisite pair lists, and perform tests on plan method at least three examples by printing proper messages. Given 4 courses and prerequisites as [[1,0], [2,0], [3,1]] It is possible to take all…
In this lab assignment you need to implement the method named middleValue, in a program named ArrayOps.java. The method accepts an array of integer values as a parameter, and returns the value in the middle of the array. For instance, if an array contains five elements, then the third element would be the middle element to be returned. However, if the array contains six elements, both the third and fourth values could be considered to be the middle elements. In this case, only return the first middle value, namely, the third element of the array. Complete the method middleValue, and test the correctness of your method in main(). Particularly, you should create two arrays (arbitrary values), one array with odd length, and the other with even length, and print out the middle values of these two arrays.
Define an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…
Hello! In java programming, I need help in creating an "AverageScores" class and constructor that accepts an array of test scores. Then include a method, in the class, that returns the average of the test scores. If any test score in the array is negative or above 100, the class should show a "DeniedException". Test the "AverageScores" class program. Thank you for your time!
Another way to write this java applacation? Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it’s not a duplicate of a number already read. Provide for the “worst case,” in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value. Here is the code I have I just want to see another way it could be written. import java.util.Scanner; public class DuplicateElimination { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int arr[] = new int[5]; int size = 0, n; for(int i = 0;i<5;i++){ System.out.print("Enter an integer between 10 and 100:"); n = scanner.nextInt(); if(size==0 || elemanVarmı(arr,size,n)){ System.out.println("This is the first time "+n+" has been entered");…
Write a code in JAVA for storing information of Employee using array. Employee attributes for storing data are id (int), name (String), salary (int), department (String) and gender (char). Gender attribute can have one of two values m/M for male and f/F for female. You are required to implement following methods in your class. Prototype and description of methods is given below. Maximum 50 Employee can be stored. 1.void add(Employee e) this method receives Employee as an argument and adds it to end of existing. In case array contains data of 50 Employee display message “Out of memory” 2.int count( ) this methods returns total number of employee whose information is stored in array. 3.void remove(int id) this method receives id as argument and remove employee whose id matches with the provided argument. 4.Employee maxPaid( ) this method returns highly paid employee. If more than one employees are highly paid than return last from the given sequence. No need to write main method or main…
The Utilities class contains three independent static methods and contains no fields (none should be added).The Utilities class contains the following 3 static methods that you must implement:1. QWERTY – If the argument is null, the length is anything other than 6, or if the element values are outside the inclusive boundof 1 to 7 throw the IllegalArgumentException with the message "Invalid parameter". Otherwise return a char array that hasinput[0] instances of 'Q', followed by input[1] instance of 'W', ....followed by input[5] instances of 'Y'. The length ofthe returned array should be the exact size needed to accommodate all the letters (no smaller or larger).2. turnTo1D – You can assume that the parameter array has at least 1 row and all rows are int array (might be an empty int array)and the parameter delta is a positive integer. The method returns a 1D array (possibly empty array) with all the values inarray that are in the range of the inclusive bound [value – delta to value +…
PLease use java In this assignment, you will implement a class called ArrayAndArrayList. This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(array) will return 9.There are 4 methods that need to be implemented in the ArrayAndArrayList class:● howMany(int[] array, int element) - Counts the number of occurrences of the givenelement in the given array.● findMax(int[] array) - Finds the max number in the given array.● maxArray(int[] array) - Keeps track of every occurrence of the max number in the givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code. See the javadoc for each methodfor instructions on what the method is supposed to do and how to write the code. It…
In ArrayUtility class, create a public static method equals that receives two arrays of int's and returns true if they have the same length and equal corresponding elements. In ArrayUtilityTest class, create a public static method equalsTest that prints the results for the following 6 cases: two empty arrays, one empty and one singleton, two singleton with the same element, two singleton with different elements, two arrays with two identical elements, two arrays with two different elements. Call only this class in the main method and check the results. In ArrayUtility and ArrayUtilityTest, design, implement and test a method named isSorted that checks if an array of int-s is already sorted, i.e. all the elements are in increasing order. In ArrayUtility and ArrayUtilityTest, design, implement and test a method named generateIntArray that generates a random array with the provided length having elements randomly generated between a minimum and maximum value, including those values create…
you created a Card class that represents a standard playing card. Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class using an array. Include methods to shuffle the deck, deal a card, return the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck.Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt along with the number of cards left in the deck. This is my Card class: mport java.util.Random; /*Card.java Richard Mino * This is a program demonstrating the use of random and predetermined objects and values in the form * of a playing card using getter/setter methods and two constructors and printing them out as a string * using the toString method */public class Card { //Set up variables for card rank and…
please use the name, phonenumber and phonebookentry to build this. The three parallel arrays are gone — replaced with a single array of type PhonebookEntry. You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes). Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods. Use the toString methods to print out information. Make 100 the capacity of your Phonebook array Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded. Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference). Do not use BufferedReader while(true) breaks The name of your application class should be Phonebook. Also, you should submit ALL your classes (i.e., Name, Strip off public from all your class…
Can you fix my code? I am still having 1 senators as it should be 2 because there are 2 senator position on the array. I think its the loop I am wrong thank you <body> <?php $candidates = [ ['name' => 'Allan', 'position' => 'President'], ['name' => 'Rhea', 'position' => 'Vice President'], ['name' => 'Jane', 'position' => 'Senator'], ['name' => 'Jfafa', 'position' => 'Senator'], ]; $counterPresident = 0; $counterVicePresident = 0; $counterSenator = 0; switch($candidates as $p) { case "1" ($p['position'] == "President") { ++$counterPresident; } else if($p['position'] == "Vice President") { ++$counterVicePresident; } else if($p['position'] == "Senator") { ++$counterSenator; } } echo "Presidents: ". $counterPresident ." candidates"; echo "<br>"; echo "Vice President: ". $counterVicePresident ." candidates"; echo…
