Hello everyone,
The Program wont run I just gave up PLEASE HELP
what i've done wrong???

on this line down it says cannot find symbol:

private static HashSet<Character> vowels = new HashSet<Character>();


here's the code:

public class TextAnalyzer {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print(" Enter Text: ");
String text = in.nextLine().toLowerCase();
 
int vowels = 0, consonants = 0, spaces = 0, numbers = 0, punctuation = 0;
for (int i = 0; i < text.length(); i++) {
 
Character c = text.charAt(i);
if (isVowel(c)) {
vowels++;
} else if (isConsonant(c)) {
consonants++;
} else if (Character.isWhitespace(c)) {
spaces++;
} else if (Character.isDigit(c)) {
numbers++;
} else if (isPunctuation(c)) {
punctuation++;
}
}
System.out.println("Number of Printable Characters is: "+ (text.length() + punctuation));
System.out.println("Number of Vowels is: " + vowels);
System.out.println("Number of Consonants is: " + consonants);
System.out.println("Number of white spaces is: " + spaces);
System.out.println("Number of digits is: " + numbers);
}
 
 
private static HashSet<Character> vowels = new HashSet<Character>();
 
private static HashSet<Character> consonants = new HashSet<Character>();
 
 
static {
 
vowels.add('a');
vowels.add('e');
vowels.add('i');
vowels.add('o');
vowels.add('u');

}

Did you import java.util.HashSet?

Hello everyone,

Normally your friendly Java compiler displays a little caret character just
underneath the offending token which, in your case, is the symbol that wasn't
found by the compiler; in the error diagnostic message itself the compiler also
mentions that symbol explicitly. If you happen to receive such messages from
the compiler please copy/paste them here verbatim instead of just mentioning
some vague indication of what exactly the compiler told you.

kind regards,

Jos

You should import java.util.HashSet and see how it goes
