This should help a little bit. It counts all the a's in the java file.

import java.nio.file.*;

import java.io.*;

public class Hw3pr2 {

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

String f = "Hw3pr2.java";

char c = 'a';

FileInputStream fis = new FileInputStream(f);

int count=0;

int r;

while ((r = fis.read()) != -1) {

if (c == (char)r){

count = count + 1;

}

}

System.out.println("Total: " + count);

}

}

You need to use a loop:

for (int i=0; i
The assignment is:

Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file.

import java.util.Scanner;

import java.io.*;

public class Hw3pr2

{

public static void main(String[] args)

{

Scanner keyboard = new Scanner(System.in);



//get the file name

System.out.println("Enter the name of a file.");

String fileName = keyboard.nextLine();

File file = new File(fileName);

Scanner inputFile = new Scanner(file);

//get the character

System.out.println("Enter any character.");

String letterInput = keyboard.nextLine();

char letter = letterInput.charAt(0);

and that's where I'm stuck. I know I can read lines in the file using inputFile.nextLine(); but how can I read individual characters?

Any help would be appreciated! Thanks!
