Create a new class in the practicum1 package named ArrayUtilities. Write a method in the class that meets the following requirements: - It should be named "arrayToString" - It should declare a parameter for an int array. - It should return a String in the same format as the example above, e.g. "[1, 2, 3]". If the array is length 0, you should return the string "[]". - It should NOT use the Arrays.toString() method - you should create and return the string yourself. - You may receive a warning from IntelliJ about using string concatenation. You may ignore it. Write a main method to test your method by calling it with one or more small arrays and printing the string(s). Example output: [] [1, 2, 3] [2, 3, 5, 7, 11, 13]

Does a method that accepts an array as an argument really have access to the original array, or is it just a copy of it?

In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location.  If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish).  So each of them should simply print out a message of the form: <Name> doesn't know how to do that. Examples: Copy the following if __name__ == "__main__" block into your hw12.py file, and comment out tests for parts of the class you haven’t implemented yet.   if __name__ == '__main__':     crew1…

Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 19 27 81 243 88 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. Hint: Method with 2 parameters (the Array) and Sum with no returns (void) 3- Your program output format must be the same as the following: =>> Array Summation Array: 31 19 27 81 243 88 100 6 10 5 Sum: 610 =>> End of the Program Documentation / Comments 31 100 6 10 5

Write an application (including algorithm) that uses a class called “Book” (seedetails below). The application must perform the following tasks. Create an array of “Book” objects (i.e., array must be able to store 2books). Create 2 “Book” objects initialized as follows.o title = “C++ Textbook”; Author = “Pete Parker”; Publisher =“Cengage”, ISBN = “0123456789”; subject = “Computer Programming”;o title = “Java Textbook”; Author = “Bruce Wayne”; Publisher = “McGrawHill”, ISBN = “9876543210”; subject = “Computer Programming”; Add the two books to the array.o Assume the two publishers have merged into a new company called“BookConglomerate”. Use a loop to create statements to modify thepublisher field with the new publisher name. Display the following information for both bookso Book Title (i.e., “C++ Textbook” or “Java Textbook”)o Authoro Publishero ISBNo SubjectThe Book class must contain the following. Constructor with parameters that initialize all instance variables title, author,…

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

How is this program written in java?

JAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way. Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.

please write in java
