. Given the following parallel arrays: int[] arrProdNumber = new int[] { 100, 115, 125, 142, 163, 199, 205, 388 }; string[] arrProdDesc = new string[] { "Kitten", "Cat", "Bird", "Chicken", "Dog", "Puppy", "Aardvark", "Zebra" }; Write a C# program that includes these arrays. Your program should then read a product number from the user and search the product number array for that number. If it is found, then your program should report the product number they entered and the corresponding product description. If the product number they enter is not in the first array, then your program should indicate that item number was not found. Here’s a sample run: //first runEnter product number: 115Item #115's product description is Cat//second runEnter product number: 1963Item #1963 does not exist in your inventory Some Random Number Generation HintsRandom rndNumber = new Random();Console.WriteLine(rndNumber.Next()); //random integerConsole.WriteLine(rndNumber.Next(101)); //random integer…

Note: Use only one java statement to accomplish both tasks. int green = colors[3][1];
Consider the following code segment that includes a method called multiply. The multiply method is a sample method for the multiplication of an n by m array and an m by p array. Suppose the multiply method is invoked as shown after replacing the element indicated as x by a number. What number should replace x so that the b3[0][0] = 9 after the execution of b3 = multiply(b1,b2)? Note that the initializeArray method puts a O to every cell of the array passed to initializeArray. *

Rewrite the client program to use the Baby class that you have done using ArrayList. You should also have the following function in this new client program: a) Enter details for each baby (name and age) and thus populate the Baby ArrayList b) Calculate and display the average age of all babies in the ArrayList c) Ask the user to enter the name of a baby, and then remove it from the ArrayList d) Allow the user to add new baby information in the ArrayList e) Output the details of each baby from the ArrayList (name and age) Compare this client program using the ArrayList with the client program you have done using array, comment on the differences between the two. Modify your client program in the last question, by adding a sort function such that when that option is selected, it sorts the ArrayList using the baby names in alphabetical order and output the details in the sorted ArrayList to a CSV (sortedbabylist.csv) file. public class Baby { private String name; private int age;…

JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.
