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!
