I have this code to count the number of * from a string entered. but I need to find it from an text file. Any idea?
import java.lang.String;
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);
}
}
}
