Question

Write a function that takes as input an English sentence (a string) and prints the total number of vowels and the total number of consonants in the sentence. The function returns nothing. Note that the sentence could have special characters like dots, dashes, and so on.

Answer 1

Answer:

   public static void vowelCount(String word){

       int vowelCount =0;

       int consonantCount =0;

       int wordLen = word.length();

       //a,e,i,o,u

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

           if(word.charAt(i)=='a'||word.charAt(i)=='e'||word.charAt(i)=='i'

                   ||word.charAt(i)=='o'||word.charAt(i)=='u'){

               vowelCount++;

           }

       }

       System.out.println("Number of Vowels: "+vowelCount);

       System.out.println("Number of Consonants: "+ (wordLen-vowelCount));

   }

Explanation:

The method vowelCount is implemented in Java

Receives a string as argument

Uses a for loop to iterate the entire string

Uses an if statement to check for vowels

Substract total vowels from the length of the string to get the consonants

See complete code with a main method below:

import java.util.Scanner;

public class num2 {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       System.out.println("Enter a String");

       String word = in.nextLine();

       //Removing all special characters and whitespaces

       String cleanWord = word.replaceAll("[^a-zA-Z0-9]", "");

//Calling the Method        

vowelCount(cleanWord);

   }

//The method

   public static void vowelCount(String word){

       int vowelCount =0;

       int consonantCount =0;

       int wordLen = word.length();

       //a,e,i,o,u

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

           if(word.charAt(i)=='a'||word.charAt(i)=='e'||word.charAt(i)=='i'

                   ||word.charAt(i)=='o'||word.charAt(i)=='u'){

               vowelCount++;

           }

       }

       System.out.println("Number of Vowels: "+vowelCount);

       System.out.println("Number of Consonants: "+ (wordLen-vowelCount));

   }

}
