import java.io.*;

import java.util.*;


public class CountVowels

{

    public static void main(String args[])throws IOException

    {

        BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));

        System.out.println("Enter the String:");

        String text = bf.readLine();

        int count = 0;

        for (int i = 0; i < text.length(); i++) {

            char c = text.charAt(i);

            if (c=='*' ) {

                count++;

            }

        }

        System.out.println("The number of vowels in the given sentence are " + count);

The given code counts the number of vowels present in the text file data.

import java.io.*;

public class CountVowels {
public static void main(String[] args)throws Exception{

try{
    FileInputStream fstream = new FileInputStream("c:/data.txt");
    DataInputStream in = new DataInputStream(fstream);
    BufferedReader br = new BufferedReader(new InputStreamReader(in));
    int count=0;
     String str="",st="";
     char ch;        
     while((str=br.readLine())!=null){
         st+=str;
     }
     for (int i=0;i<st.length();i++){
      ch = st.charAt(i); 
      if(( ch == 'a') ||( ch == 'e') ||( ch == 'i') ||( ch == 'o') ||( ch == 'u')){
        count++;
      }
     }
     System.out.println("Number of vowels in the file: "+count);
      br.close(); 
    }
     catch (Exception e) {
     System.err.println(e);
    }
   }
 }
