- Need help writing the following method: getRegisteredStudents() – returns an array of type Student[], namely the registered Students. The length of the array is the current size (number of students) of the course. public Student[] getRegisteredStudents() { // insert your 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<>();…Provide a code segment that creates an arraylist of three integers and prints these values on the screen. Then add two more integers and print out the last integer on the screen. Note: You are free to choose integers.Write a program that do the following: Ask the user to input his/her first name and store it in a String variable. Create an ArrayList with the type String. Each letter of the inputted name should be stored in a separate element of the ArrayList. Print the ArrayLists. Note: Your answer should have the code as text, as well as a screenshot of the code with the output. The inputted name should be your first name. Name : Rabab
- 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…Please add comment on each line Thank you very much! Write a static method, getBigWords, that gets a single String parameter and returns an array whose elements are the words in the parameter that contain more than 5 letters. (A word is defined as a contiguous sequence of letters.) EXAMPLE: So, if the String argument passed to the method was "There are 87,000,000 people in Canada", getBigWords would return an array of two elements, "people" and "Canada". ANOTHER EXAMPLE: If the String argument passed to the method was "Send the request to support@turingscraft.com", getBigWords would return an array of three elements, "request", "support" and "turingscraft".Create an ArrayList, Named it Husnain that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say so. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once

- Write an application that stores the following nine integers in an array: 10, 15, 19, 23, 26, 29, 31, 34, 38. Display the integers from first to last, and then display the integers from last to first. ***can you provide comments explaining your methods? Thank you for all of your help ^_^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…Write an application that stores the following nine integers in an array: 10, 15, 19, 23, 26, 29, 31, 34, 38.
