Write a program that uses a scanner to report some statistics about words in an input sentence ( see Section 7.8). The outputs should be the number of words in the sentence, the average word length, and the length of the sentence.

import java.util.Scanner;

public class JavaApplication77 {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter a sentence:");

       String sentence = scan.nextLine();

       String [] arr = new String[sentence.length()];

       arr = sentence.split(" ");

       System.out.println("There are "+arr.length+" words in the sentence.");

       int count = 0;

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

           count += arr[i].length();

       }

       System.out.println("The average length of a word in your sentence is "+(count/arr.length)+" characters");

       count = 0;

       System.out.println("Your sentence is "+sentence.length()+" characters long.");

   }

}

For the length of a sentence, I included spaces as characters but I did not do this for the length of a word. I hope this helps!

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.
