Write a program with functions that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another function that accepts a string as an argument and return the number of consonants that the string contains. The application should let the user enter a string and should display the number of vowels and the number of consonants it contains.

import java.util.Scanner;

public class num11 {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       System.out.println("Enter a word or phrase");

       String word = in.nextLine();

       //Calling the methods

       System.out.println("Total vowels in "+word+" are "+numVowels(word));

       System.out.println("Total consonants in "+word+" are "+numConsonants(word));

   }

   public static int numVowels(String word){

       //Remove spaces and convert to lowercase

       //Assume that only correct character a-z are entered

       String newWord = word.toLowerCase().replaceAll(" ","");

       int vowelCount = 0;

       for(int i = 0; i <= newWord.length()-1; i++){

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

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

               vowelCount++;

           }

       }

       return vowelCount;

   }

   public static int numConsonants(String word){

       //Remove spaces and convert to lowercase

       //Assume that only correct character a-z are entered

       String newWord = word.toLowerCase().replaceAll(" ","");

       int consonantCount = 0;

       //Substract total vowels from the length of the word to get the consonants

       consonantCount = newWord.length()-numVowels(word);

       return consonantCount;

   }

}
