1- Write a class called items that has member variables name (string), price (double),quantity (integer). In main program, create an array of type items called arrayltem andstore several item objects in this array. Note that main should create several itemobjects and save these objects in arrayltem. Write a static method called totalCost thataccepts an array of items. This static method must calculate and return the total cost ofitems stored in the array.2- Write a generic method called minimum that accepts four items and find the minimumof them.3- Test your class with Integer, Double, Character, String and Car objects.

Problem 11 of an Create a class ArraysAndMethodsGames, Write a method that returns the average array with the following header: public static double average(double[] array); Write a method to initialize the array with the following header: public static double[] readArray(): The readArray method prompts the user to enter ten double values and initializes a newly array with these values. It returns the array to main.

1. Deck.java The Deck class represents a deck of cards. It starts off with 52 cards, but as cards are dealt from the deck. the number of cards becomes smaller. The class has one private instance variable that stores the Cards that are currently in the Deck: private Card] carde; Important Note: The first Card in the array will be considered the card that Is at the top of the deck. Whon cards aro removed from the deck they will be removed from the front of the array. You must implement the flollowing methods for the Deck class: • public Dock) This constructor initializes the Deck with 52 card objacts, representing the 52 cards that are in a standard deck. The cards must be ordered as in the diagram below: Important: The FIRST card in your array should be the Ace of Spades, and the LAST card should be the King of Diamonds. Note that in the picture below, the Ace of Spades is at the TOP of the deck, which is to the left. A234567890 J.0KA234567 25456 10KA2 S45 57|8|90U.0高 • public Deck(Deck…
a)Develop a method called normalizeGrades() in Java following the details below: The method should accept an array of numeric grades as argument. Each grade in the array is a numeric value (of type double) between 0 to 100. b)The method should create an integer array of grades, following: If a grade in the array is greater than 50, then the method should round the numeric grade to the nearest integer value using Math.round() method, and then again round it to an integer grade to a nearest multiple of 5. If a grade in the array is less than or equal to 50, then the method should round the numeric grade to the nearest integer value using Math.round() method. c)The method should create a character array of letter grades, using a switch statement by translating the integer grades created in (b) to an array of letter grades of type character, following the grade notation: 100 or 95 or 90 85: A 70, 75, 80: B 55, 60, 65: C 50: D 0 to 49: F d)The method should print the integer array of…
In C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.
In C++ Create a class called Student. Each student should have a name and ID number (an int). They should also have a ptr to a dynamic array called Grades. The public methods for Student should be: getName, setName, getID, setID, setGrades, getGrades. In the constructor you should initialize Grades to be an array of size 4 with the values 0 for each position. Make sure that you use THIS properly. Create 2 students, assign one object to another and show that when you assign grades to one it effects the other equally.
