The java Strings

[greenteachacha]

Good evening everyone, i would like to ask what type of String that can use in this program?

Create a program that will receive a string from user and count the number of vowels in the string.
i have try to use this s.indexOf() but can't
can anyone teach me thanks

First of all, please choose the correct sub-forum when you posting gain. This is not the correct place. I'll move your question to the correct place this time.

What you have to do is, take each character of the string and check it for a vowel or not.

but how the code write?

[Eranga]

You should do it. This is a forum, not a code bank. No one wants to do your homework. First show your effort, and if you have any question please ask it more clearly. We all can help you.

i didn't understand what you reply in the second post. so i just asking like that. i have let you know my way is using s.indexOf() but i still can't get it. erm, is ok..

What Eranga is telling you is that you have to show us why it it's working for you. What have you tried? Let's see your code.

Luck,

oh. erm.. icic sorry Eranga. this is my code.
hope you all can help me

import java.io.*;
class countvowel
{
static DataInputStream s=new DataInputStream(System.in);
public static void main(String args [])throws IOException
{
String anyvowel;
System.out.println("Enter a string: ");
anyvowel=s.readLine();
System.out.println("String: "+anyvowel);
System.out.println();
int c = 0 ;
for (int b = 0 ; b < anyvowel.length() ; b++) {
if (anyvowel.charAt(b) == 'a' || anyvowel.charAt(b) == 'e'||anyvowel.charAt(b)=='i'||anyvowel.charAt(b)== 'o'||anyvowel.charAt(b)=='u') {
c++;
System.out.println("The vowel that have in the string:"+ anyvowel.charAt(b));
}
}
System.out.println("The total number of vowel in the String: "+c);
}
}

[Eranga]

Try this in the if logic.

if(......)
{
      c++;
      System.out.println("Vowel " + anyvowel.charAt(b) + " found at " + b);
}

Few things to pay your attention.

1. Please use the code tags when you posting again. Un-formatted cods are hard to read.

2. Naming conversions, in Java follows camel case. http://java.sun.com/docs/codeconv/ht...ions.doc8.html
