Thread: Need help with program please: getting symbol error

I have an assignment in my intro level programming class to write a program to count the number of times a character occurs in a file. My professor showed us how to write this program in class but I continue to get a missing symbol error on my FileInputStream line. Could someone please tell me how to fix this? Ignore my awful formatting in the program and realize that this is how my professor wants us to write this program. So try to keep it in this mindset. Appreciate the help! Here is my program as of now.

import java.util.*;
 
public class Prog7
{
  public static void main(String[] args)
{
  Scanner keybd = new Scanner(System.in);
 
String filename;
char ch;
int count;
 
//Prompt the user for filename.
 
filename = keybd.next();
 
count = frequency(ch,filename);
 
System.out.println("In the file " + filename + ", the character " + ch + " appears " + count + " times.");
}
 
//Given a character ch and a filename.
//Prints the number of times the character appears
//in the file. Returns the count.
 
 
public static int frequency(char ch, String fname)
{
FileInputStream f = new FileInputStream(newFile(fname));
 
int count;
char nextChar;
 
count=0;
nextChar=f.read();
 
while(nextChar != -1)
{if(nextChar==ch)
  count++;
 
  nextChar=f.read();
}
f.close();
 
return count;
}
}
