All or Nothing Implement a public class named All that provides a single static method name orNothing. orNothing accepts two parameters: a count (int) and a boolean and returns an array of Items of size count. If the passed boolean is true you should return an array where all references refer to the same Item. If the passed boolean is false you should return an array where all references refer to different Item instances. You can create Item instances with an empty constructor: new Item().

- Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
- Java Code Write a Windspeed class that stores the total winsoeed for each of 12 months into an array of double windspeedmeasures. The windspeed shoukd be collected from the user.

The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers for monthly rainfall figures.JAVA Include Code Comments create a public class named ArrayUtility In ArrayUtility class, create a public static method toString that receives an array of int's, a start string, a separator string and an end string. It returns a String starting with the start string, followed by the array elements separated by the separator and ending with the end string. create a public class named ArrayUtilityTest In ArrayUtilityTest class, create a public static method toStringTest that prints the results for the following 5 lengths of arrays, using different types of brackets and separators for each: empty, singleton, two elements, 5 elements and 20 elements. Call only this class in the main method and check the results. 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…
- 2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.Sultan Qaboos University Department of Computer Science COMP2202: Fundamentals of Object Oriented Programming Assignment # 2 (Due 5 November 2022 @23:59) The purpose of this assignment is to practice with java classes and objects, and arrays.

Probability differs in the roll of two dice compared to a single die due to varied combinations. Dice Roll Series: User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls. Java classes: DiceRoller, Indicator, Validator. DiceRoller: Arrays: rollSeries (captures results), statIndicators (stores statistical indicators). Constructor rolls dice as per user request. Methods collect stats and print the report. Indicator class: Contains dicePairTotal and dicePairCount. Displaying Results: Sort statIndicators array before display. Indicator objects sortable by dicePairCount (implements Comparable). Example output:-----------------------dicepair rolltotal count percent---- ------ --------7 5 50%10 2 20%4 2 20%2 1 10% Tasks:…
