In Java:

Write a program (method main) using an array to solve the following problem:

• Prompt the user to enter a String of data • Using the charAt(index) method in the String class to access each character in the string individually, produce a count of the number of word lengths • Count only letters (regardless of upper or lower case) and treat spaces, numbers and punctuation as word separators. • Display the number of words and lengths for all non-zero lengths, and the total number of words

Example 1: (green is user input)

2 2 letter words

2 3 letter words

1 4 letter words

Explanation / Answer

Hey, the program for it is as follows:

import java.util.Scanner;

public class WordCounter {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
       System.out.println("Enter the phrase");
       Scanner scanner = new Scanner(System.in);
       System.out.flush();
       int arr[]=new int[200];
       String phrase= scanner.nextLine();
       int count=0;
       for(int i=0;i<phrase.length();i++){
           if(Character.isAlphabetic(phrase.charAt(i))){
               count++;
               if(i==(phrase.length()-1)){
                   arr[count]++;
               }
           }
           else
           {
               arr[count]++;
               count=0;
           }
       }
       int total=0;
       for(int j=1;j<200;j++){
           if(arr[j]!=0){
               System.out.println(""+arr[j] + " " + j + " letter words") ;
               total+=arr[j];
           }
       }
       System.out.println(total + " total words");
      
      
      
   }

}
