Write a Java program to perform the following tasks: The program should ask the user for the name of an input file (scores.txt). The input file should contain 10 records. Each record in the input file should consist of a name and score between 0 and 100 (inclusive). Eg: fred 95 The program should open the input file as a text file (if the input file does not exist it should throw an exception) and read the contents line by line. Store each record in an array of a user-defined Score class. The Score class can be kept very simple with 2 instance variables, a default constructor, get and set methods for the instance variables. Now process the array of Score class objects to determine: • The average of all scores • The largest score • The smallest score

1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.

In java create a function searchstd() that reads a search record  from a text file file.txt when the function is called in main

In Python: If you call the index method to locate an item in a list and the item is not found, this happens     A ValueError exception is thrown     An InvalidIndex exception is thrown     The method returns -1     Nothing happens, The method does not return anything and the program continues execution

Chapter 4. Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file. The program should read all the numbers from the given file and display the total and average of all numbers in the following format (three decimal digits): Total: nnnnn.nnn Average: nnnnn.nnn Class name: FileTotalAndAverage   Here is a working code but please modify it so it passes the test cases because I run it it does not work: Also I do not need Goodbye. I run it through Hypergrade which has all the test cases and it does not pass. It says 0 out of 7 passed import java.io.File; //importing java.io.Fileimport java.io.FileNotFoundException; //importing FileNotFoundException for exception handlingimport java.util.Scanner; //importing Scanner for user inputpublic class FileTotalAndAverage { //class FileTotalAndAverage   public static void main(String[] args) throws FileNotFoundException {       Scanner keyboard = new Scanner(System.in); //declaring and…

Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate lists, and outputs the available food items in the following format: name (category) - description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t'). Ex: If the input of the program is: food.txt and the contents of food.txt are: Classic ham sandwich Available sandwich Chicken salad sandwich Not available Classic cheeseburger Cheeseburger Not available Salads Water 16oz bottled water Available Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Beverages Beverages Mexican food…
