Hash table problem

[NoOneCanHelpMe]

Hello everyone,
could someone help me please,
I want to print out the frequency of each vowel in the string and I think I will need to use the hash table I already have but im not sure how to do it

Thank you in advance

import java.util.*;
public class TextAnalyzer {
public static void main(String[] args) {
Scanner in = new Scanner(System. in);
System.out.prin t(" Enter Text: ");
String text = in.nextLine().t oLowerCase();

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.isWh itespace(c)) {
spaces++;
} else if (Character.isDi git(c)) {
numbers++;
} else if (isPunctuation( c)) {
punctuation++;
}
}
System.out.prin tln("String length is: "+ text.length()+" characters");
if (vowels % 2 == 0 && consonants % 2 == 0)
System.out.prin tln("The ratio of Vowels to Consonants is: " +vowels/2+ ":" +consonants/2);
else if (vowels % 3 == 0 && consonants % 3 == 0)
System.out.prin tln("The ratio of Vowels to Consonants is: " +vowels/3+ ":" +consonants/3);
else if (vowels % 5 == 0 && consonants % 5 == 0)
System.out.prin tln("The ratio of Vowels to Consonants is: " +vowels/5+ ":" +consonants/5);
else
System.out.prin tln("The ratio of Vowels to Consonants is: " +vowels+ ":" +consonants);

if ((text.length() - spaces) % 2 == 0 && spaces % 2 == 0)
System.out.prin tln("The ratio of Printing to Non-Printing is: " +(text.length()-spaces)/2+ ":" +spaces/2);
else if ((text.length() - spaces) % 3 == 0 && spaces % 3 == 0)
System.out.prin tln("The ratio of Printing to Non-Printing is: " +(text.length()-spaces)/3+ ":" +spaces/3);
else if ((text.length() - spaces) % 5 == 0 && spaces % 5 == 0)
System.out.prin tln("The ratio of Printing to Non-Printing is: " +(text.length()-spaces)/5+ ":" +spaces/5);
else
System.out.prin tln("The ratio of Printing to Non-Printing is: " +(text.length()-spaces)+ ":" +spaces);
{
if (vowels >0)
{
System.out.prin tln(" appears "+" times,which is: "+ (double)vowels * 100/(text.length())
+ "% from the whole string.");
}
}
}

Where is the Hashtable in your code?

ops the wrong code, but nvm I've just read that my hashtable is rubbish and I deleted it :(
Anyway, any suggestions how to make my program to printout the frequency of each vowel?
Thank you

Why don't you use regular expressions for that. Because the following is a
complete giveaway there is no explanation. Read the API documentation for
the relevant classes and methods:

[code=java]
int frequencyOf(Str ing s, String pattern) {
return s.length()-s.replaceAll(pa ttern, "").length( );
}
[/code]

Call that method with your text for the first parameter and, say, "[aA]" for its
second parameter. It'll return the number of lowercase or uppercase letters 'a'
in your text. If the second parameter is "[aAeEiIoOuU]" it returns the count of
any vowel in your text.

kind regards,

Jos

ps. you already have a thread running for exactly the same question. Don't double
post; it is confusing for readers who are willing to help you.
