- Programming in C#: Write a console-based application that displays every perfect number from 1 through 10000. A number is perfect if it equals the sum of all the smaller positive integers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it and their sum is 6. Use format strings(field size 8, right alignment) to show all perfect numbers. Display the results as seen below. 6 28 496 8128Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below)Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines. Example Execution (user input in green) Please enter a sentence: Hey there! Your sentence printed vertically is: H e t h e r
- In java please help with the following: Given a string that contains space separated words, write an application that displays the words in ascending order (If two words are the same, display only one). You need to use the right data structure for storing the words. For example, for input:String input="apple banana apple orange blueberry"; The program will print out: apple banana blueberry orangeI need help with creating a Java program described below: Slot Machine SimulationAsks the user to enter the amount of money he or she wants to enter into the slot machine. Instead of displaying images, the program will randomly select a word from the following list:Cherries, Oranges, Plums, Bells, Melons, Bars To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries; if the number is 1, the selected word is Oranges; and so forth. The program should randomly select a word from this list three times and display all three of the words. If none of the randomly selected words match, the program will inform the user that he or she has won $0. If two of the words match, the program will inform the user that he or she has won two times the amount entered. If three of the words match, the program will inform the the user that he or she has won three times the amount entered. The program will ask whether the user…Using C# create a console app doing the following Write a method that takes two integers and displays their sum. Write a method that takes five doubles and returns their average. Write a method that returns the sum of two randomly generated integers. Write a method that takes three integers and returns true if their sum is divisible by 3, false otherwise. Write a method that takes two strings and displays the string that has fewer characters. Write a method that takes an array of doubles and returns the largest value in the array. Write a method that generates and returns an array of fifty integer values. Write a method that takes two bool variables and returns true if they have the same value, false otherwise. Write a method that takes an int and a double and returns their product. Write a method that takes a two-dimensional array of integers and returns the average of the entries.
