Answer:
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;
}
}
Explanation:
- Create two methods vowelCount() and consonantCount() both accepts a string parameter and returns an int
- vowelCount() Uses a for loop to count the occurrence of the vowels (a,e,i,o,u) in the string and returns the count.
- consonantCount calls vowelCount and subtracts the vowelCount from the string length
- In the main Method the user is prompted to enter a string
- The two methods are called to return the number of vowels and consonants
- Observe also that it is assumed that user entered only strings containing the character a-Z.
- Observe also that the string is converted to all lower cases and whitespaces removed.
