    Default get vowel character from strings

    Hi everyone,

    A title said all. i need actually to find a vowel(a,e,i,o,u) in a string.
    my code counts how many vowels are in the string that's fine but i need to find a vowel character too..

    any idea how to achieve this ?


    Here is my code...

    import java.io.*;
    import java.lang.*;
    public class VowelsExample {
     
    public static void main(String[] args) throws IOException {
    BufferedReader input = new BufferedReader (new InputStreamReader(System.in));
     
    int count = 0;
    int i;
     
    System.out.println("Enter a string :");
    String in = input.readLine();
     
    for (i=0; i<in.length(); i++){
    vowel[in.length()] = in.charAt(i);
    if(vowel[in.length()]=='a' || vowel[in.length()]=='A' || vowel[in.length()]=='e' || vowel[in.length()]== 'E' || vowel[in.length()]=='i' || vowel[in.length()]=='I' || vowel[in.length()]=='o' || vowel[in.length()]=='O' || vowel[in.length()]=='u' || vowel[in.length()]=='U')
    count ++;
    }
     
    System.out.println("total vowels are : " +count);
     
    }
    }

    What do you mean by find a vowel? Return its position? Return which vowel it was? What if there are more than one?

    exactly , if i enter a string like "Hello"

    count will tell me there are 2 vowels and
    it should tell the vowels are "e o".

    Okay, so where are you stuck? What have you tried? How would you do this with a piece of paper and a pencil, without a computer?

    There are syntax errors in your program. What is vowel?
    Also, see String tutorials to solve your problem. There are bunch of functions provided in String that might help you.
