- Create a static method called createOrderArray. This function should take in a String as a parameter and return an array of Orders.a. The string will be formatted like “LCIFPLLP”, each letter representing a different order. There will always be at least 1 letter in the input. For example, “LCIFPLLP” would mean: LATTE, COFFEE, ICED_COFFEE, FRAPPEE, PASTRY, LATTE, LATTE and PASTRY.b. Create an array of Orders, and fill it with the respective Order enum values according to• L – LATTE• C – COFFEE• I – ICED_COFFEE• F – FRAPPE• P – PASTRY For the example above (the string “LCIFPLLP”), the array should contain eight orders, with a LATTE first, COFFEE second, ICED_COFFEE third, FRAPPEE fourth, PASTRY fifth, LATTE sixth, etc.c. Return the newly created array.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…Given a base Plant class and a derived Flower class, complete main() to create an ArrayList called myGarden. The ArrayList should be able to store objects that belong to the Plant class or the Flower class. Create a method called printArrayList(), that uses the printInfo() methods defined in the respective classes and prints each element in myGarden. The program should read plants or flowers from input (ending with -1), add each Plant or Flower to the myGarden ArrayList, and output each element in myGarden using the printInfo() method. Ex. If the input is: plant Spirea 10 flower Hydrangea 30 false lilac flower Rose 6 false white plant Mint 4 -1 the output is: Plant 1 Information: Plant name: Spirea Cost: 10 Plant 2 Information: Plant name: Hydrangea Cost: 30 Annual: false Color of flowers: lilac Plant 3 Information: Plant name: Rose Cost: 6 Annual: false Color of flowers: white Plant 4 Information: Plant name: Mint Cost: 4 import java.util.Scanner;import java.util.ArrayList;import…
- 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 +…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.a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b. Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4] b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array. class Main {public static int[] createArray(int a, int b) {}public static void main(String[] args) {}}
- Which of the above choices (A, B, C or D) prints the name of each animal in the animalList object created from a previous question?// Assume that these accessor and mutator methods exist in the Animal class: // public void setAnimalName(String newName) { ... } // public String getAnimalName() { ... } // A for(int i = 0; i < animalList.length(); i++) { Animal tempAnimal = animalList[i]; System.out.println( tempAnimal.getAnimalName()); } // B for(int i = 0; i < animalList.length; i++) { Animal tempAnimal = animalList[i]; System.out.println( tempAnimal.getAnimalName()); } // C for(int i = 0; i < animalList.length; i++) { Animal tempAnimal = animalList[i]; System.out.println( tempAnimal.setAnimalName()); } // D for(int i = 0; i < animalList.length; i++) { Animal tempAnimal = animalList[i]; System.out.println(tempAnimal.animalName); }Need help writing the method: getWaitlistedIDs() – returns an array of type int[], namely the ids of students in the waitlist. public int[] getWaitlistedIDs() { // insert solution here and modify the return statement return null; } For context public class Course { public String code; public int capacity; public SLinkedList<Student>[] studentTable; public int size; public SLinkedList<Student> waitlist; public Course(String code) { this.code = code; this.studentTable = new SLinkedList[10]; this.size = 0; this.waitlist = new SLinkedList<Student>(); this.capacity = 10; } public Course(String code, int capacity) { this.code = code; this.studentTable = new SLinkedList[capacity]; this.size = 0; this.waitlist = new SLinkedList<>(); this.capacity = capacity; }The array of Vehicles below, write the static method,findMin which returns the lowest price of any Vehicle in the ArrayVehicle [] myVehicles = new Vehicle[10];public static double findMin(Vehicle [] theVehicles){}
- Write a class ArrayClass, where the main method asks the user to enter the four numbers. Create a method printArray that prints the array whenever required (use Array.toString method).
