First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "LetterCount" (without the quotation marks) according to the following guidelines. You are going to write a program that reads a txt file and reports what the most common letter in a different txt file. The program needs to count all the letters so that lowercase letters are counted the same way as uppercase letters. For example, A and a would count towards the same letter. A sample outline is: //Establish fileName, the String that is "data. txt" //Go through file and count the amount of letters in an array //Find the index of the largest value //Determine all the letters that were used the most and store as a Character ArrayList

See explaination

Explanation:

// LetterCount.java

import java.io.File;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.NoSuchElementException;

import java.util.Scanner;

public class LetterCount {

public static void main(String[] args) {

// setting up a Scanner to read from keyboard

Scanner scanner = new Scanner(System.in);

try {

// asking and reading input file name

System.out.print("Enter name of input file: ");

String file = scanner.nextLine();

// reinitializing scanner to read from input file. this will throw

// file not found exception if file is not found.

scanner = new Scanner(new File(file));

// opening a file writer to create and write into output.txt file

PrintWriter writer = new PrintWriter(new File("output.txt"));

// creating a String containing all 26 alphabets

String alphabet = "";

// creating an array containing 26 integers, all initialized to 0

int counts[] = new int[26];

// looping through the file

while (scanner.hasNext()) {

// reading next line, converting to lower case

String word = scanner.next().toLowerCase();

// looping through each character in current word

for (char c : word.toCharArray()) {

// finding index of c in alphabet

int index = alphabet.indexOf(c);

// if c is an alphabet, the index value will not be -1

if (index != -1) {

// incrementing counter at index position

counts[index]++;

}

}

}

// closing input file

scanner.close();

int largestCount = 0; // to store largest count of a character

String mostCommon = ""; // to store the character(s) that occur the

// most

// looping through counts array, finding the largest value

for (int i = 0; i < counts.length; i++) {

if (counts[i] > largestCount) {

// updating largestCount and mostCommon

largestCount = counts[i];

mostCommon = alphabet.charAt(i) + "";

} else if (counts[i] == largestCount) {

// same largest count, appending to mostCommon string

mostCommon += " " + alphabet.charAt(i);

}

}

// writing results to output file

writer.println("The most common letter(s): " + mostCommon);

writer.println("Count of occurrances: " + largestCount);

// closing file, saving changes, alerting user

writer.close();

System.out

.println("done! please check output.txt file for results.");

} catch (IOException e) {

// will be executed when the input/output file cant be opened or

// found, or if there is an error while reading the file

System.out.println(e.getMessage());

} catch (NoSuchElementException e) {

// will occur when there is no input provided for input file name.

System.out.println("No input!");

}

}

}

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
