Answer 1

Made something like this hope this helps, this will give vowels,consonants of each word

public static void main (String args[]) 
        {
                Scanner stdin = new Scanner(System.in);
                String string1;
                System.out.println("Enter a string");
                string1 = stdin.nextLine();
                string1 = string1.toLowerCase();
                int count = 0;
                int vowels = 0;
                int consonants = 0;
                for (String retval: string1.split(" ")){
                     for (int i = 0; i < retval.length(); i++)
                {
                        char ch = retval.charAt(i);
                        if (ch == 'a' || ch == 'e' || ch == 'i' || 
                                        ch == 'o' || ch == 'u')
                        {
                                vowels++;
                        }
                        else
                        { 
                                consonants++;
                        }
                }
            System.out.println(retval.substring(0, 1).toUpperCase() + retval.substring(1)+" has "+vowels+" vowels and "+consonants+" cosonants");
         vowels=0;
         consonants=0;
      }

        }

Answer 2

Here is a simpler way of doing this, hope this helps:

public static void checkVowels(String s){
    System.out.println("Vowel Count: " + (s.length() - s.toLowerCase().replaceAll("a|e|i|o|u|", "").length()));
    //Also eliminating spaces, if any for the consonant count
    System.out.println("Consonant Count: " + (s.toLowerCase().replaceAll("a|e|i|o| |u", "").length()));
}

Answer 3

My code without scanner and maybe not very simple, but:

public class Main{
public static void main(String[] args) {

    String test = "qwertyYVTA";
    test = test.trim();
    int vowels = 0;
    int consonants = 0;

    Pattern patternVow = Pattern.compile("[eyuioa]", Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE);
    Matcher matcherVow = patternVow.matcher(test);
    while (matcherVow.find()) {
        vowels++;
    }

    Pattern patternCons = Pattern.compile("[wrtpsdfghjklzxcvbnm]", Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE);
    Matcher matcherCons = patternCons.matcher(test);
    while (matcherCons.find()) {
        consonants++;
    }
    System.out.println("Vowels in test String is " + vowels);
    System.out.println("Consonants in test String is " + consonants);
    }
}
