9. Complete a program in a class ToyCounter that computes the cost of toys sold in a shop. Five kinds of toys-Zen, Leo, Star, Sam, and Barry-are stocked and cost, respectively, RM0.75, RM0.50, RM1.25, RM0.80 and RMO.75 per toy. Create an array of strings that holds the names of these toys. Create another array that holds the cost of each corresponding toy. Your program should read the name of a toy and the quantity desired by a customer. Locate the toy in the name array and use that index to find the cost from the cost array. Compute and print the total cost of the sale as output in Figure 8 below: E Output - test (run) #4 x :unz What kind of£ toy would you like? zen How many toy would you like? 10 zen: 10 at RMO.75 will cost RM7.5 Figure 8 Insert your answer here (Figure 9): import java.util.Scanner: public class ToyCounter public static void main (String [] args) double totalcost; int number; String() toyName - {"zen", double [] prices = (0.75, 0.50, 1.25, 0.80, 0.75): "leo", "star",…
CODE IN JAVA PLEASE SEE THAT THERE SHOULD BE TWO .JAVA FILES ONE WITH CLASS AND OTHER WITH THE MAIN METHOD 3. 2D Array Write a class called TwoDArray that has the following behaviors for an array of ints. getTotal – Accepts a 2-D array as its argument and returns the total of all the values in the array getAverage – Accepts a 2-D array as its argument and returns the average of all the values in the array getRowTotal - Accepts a 2-D array as it first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. getColumnTotal - Accepts a 2-D array as it first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column. getHighestInRow - Accepts a 2-D array as it first argument and an integer as its second argument. The second…
Extend the Array class adding the following two newmethods:A) the method called min that returns the smallest numberin the array.E.g., applying min to the array [−3, 2, 0, −10, 9, 7], we get −10.B) the method called reverse that reverses the array.E.g., applying reverse to the array [−3, 2, 0, −10, 9, 7], we change itto [7, 9, −10, 0, 2, −3].

RU Rotten Tomatoes . Write a program RURottenTomatoes.java that creates a 2 dimensional integer array of movie ratings from the command line arguments and displays the index of the movie that has the highest sum of ratings. Ratings range from 1 to 5 (inclusive). The rows of the 2D array correspond to movie reviewers and the columns of the 2D array correspond to movies. The reviewer at index 2 gave movie at index 0 a rating of 4. Take a look at the following example for an explanation on the command line arguments sequence. java RURottenTomatoes 3 2 5 2 3 3 4 1 0 1 0 5 2 1 3 3 2 4 1 The first argument corresponds to the number of reviewers and the second argument corresponds to the number of movies (the dimensions of the 2D integer array).

-CLO3- Question No 1: (Array of primitive values) Initialize an array of double values of size 10, with user input. Then calculate and display the sum and average of these values. Question No 2: (Array of objects) Create a class Student having rollno and name as private instance variables. write a program that creates studentArray of five students; it then initializes all students rollno and name by using an input function that will initialize and return an array of five students. and display function that displays the values of all students the array which is passed to it.
Class Gradebook2D The class Gradebook2D will produce the same output of the class Gradebook1D, but the implementation will be slightly different. You will need to use only two arrays:  One array of type int to store all the ID's (just like the previous class).  One two‐dimensional array of type double to store all the scores for all quizzes. Example: Assume there are 10 students in the class, then the id array will have 10 indices. 0 1 2 3 4 5 6 7 8 9 132 451 854 523 153 588 351 856 142 445 Each quiz array will store in the index that corresponds to the student the score for the quiz. 0 1 2 3 4 5 6 7 8 9 100.0 90.0 85.0 92.0 75.0 93.0 98.0 100.0 95.0 87.0 90.0 87.0 92.0 95.0 78.0 84.0 88.0 96.0 100.0 95.0 100.0 98.0 85.0 98.0 87.0 89.0 92.0 88.0 92.0 97.0 Student with ID 153, at index 4, has taken all three quizzes with scores 75.0 (quiz 1), 78.0 (quiz 2) and 87.0 (quiz 3). Note: The two dimensional array can be represented also with the rows being the students and the columns…
JAVAWrite a program that searches person's name and display all matched name. For example, if a user inputs the letter "Davis", the program searches all name which includes "Davis" in an array. Then, display all matched names on the screen. You must declare a single dimensional array which has all people’s name. Use methods of string class
Write a CarParking class to model a multistory car parking building. This class should contain a 3- dimensional array of type Vehicle. The third dimension of the array simply represents the number of floors of the building while the first and second dimensions are the number of rows and columns in every floor. By default, there are 3 floors, 7 rows and 7 columns in a building. However, the user should be able to specify the maximum number of floors, rows and columns at the time of creating a CarParking object. In addition to the constructors, this class should provide the following methods: O public boolean isOccupied (int floor, int row, int col) this method returns true if the location specified by the floor, row and column is already occupied by a vehicle. o public void add (Vehicle v) this method will add the vehicle at the next empty slot. Slots are field row by row (from left to right) starting from the ground floor. public Vehicle remove (int floor, int row, int col, double…
Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operator
Problem: We need a program that takes 8 products and makes calculations and informs the user. Products have name, type and cost. Write the program that takes name,type and cost information from the user and saves the product objects to an array and calculates the total cost, the one with the most cost and the one with the least cost. For example: Banana Fruit 10 Apple Fruit Trousers Textile 50 T-Shirt Textile 30 Pencil Office 15 Office Раper Strawberry Computer 10 Fruit 20 Electronics 6000 Total Cost: 6140 TL Most Expensive: Computer Least Expensive: Apple
