Question

consonantCount (s2) Write the function consonantCountthat counts how many times a consonant (either lowercase or uppercase) occurs in a string. It takes a string sas input and returnsan integer, the number of consonants in the string. For this question, yand Yare not consonants. Please use a for loop to do the computation. Please do not use a brute force solution (comparing against one consonant at a time): it will not receive credit.

Answer 1

Answer:

public static int consonantCount(String str){

       int numOfConsonants =0;

       int numOfVowels =0;

       String word = str.toLowerCase();

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

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

                   ||word.charAt(i)=='e'||word.charAt(i)=='u'||word.charAt(i)=='y'){

              numOfVowels++;

           }

       }

       numOfConsonants = (word.length()-numOfVowels);

       return numOfConsonants;

   }

Explanation:

Using Java programming Language

• Create two variables int numOfConsonants and int numOfVowels To hold the number of consonants and vowels repectively
• The english vowels for this question includes y or Y
• Convert the string entered into all lower case letters using java's toLowerCase method
• Using a for loop count the total number of vowels in the string
• Subtract the number of vowels in the string from the length of the string to get the number of consonants
• return the number of consonants
• Consider a complete program below where a user is prompted to enter a string, the string is stored in a variable, the string is cleaned (Removing all special characters and whitespaces)
• The method cosonantCount is then called

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 a = in.nextLine();

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

       System.out.println("The number of consonants in the word are "+consonantCount(cleanText));

   }

   public static int consonantCount(String str){

       int numOfConsonants =0;

       int numOfVowels =0;

       String word = str.toLowerCase();

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

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

                   ||word.charAt(i)=='e'||word.charAt(i)=='u'||word.charAt(i)=='y'){

              numOfVowels++;

           }

       }

       numOfConsonants = (word.length()-numOfVowels);

       return numOfConsonants;

   }
