Java reading data from a .txt file and outputting it to an output.txt file

Question

My code:

import java.io.*;
public class ProgramSix {

    public int count(String fileName, char charToSerach) throws FileNotFoundException, IOException {

        char lower = Character.toLowerCase(charToSerach);
        char upper = Character.toUpperCase(charToSerach);

        int count = 0;

        try (BufferedReader reader = new BufferedReader(new FileReader("xanadu.txt"))) {
            int ch = 0;
            while ((ch = reader.read()) != -1) {
                if (lower == ch || upper == ch) {
                    count++;
                }
            }
        }
        System.out.println("The character '" + charToSerach + "' appears: " + count + " times in the .txt file");
        return count;
    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            Program6 program6 = new Program6();

            String fileName = "xanadu";
            int numAs = programSix.count(fileName, 'a');
            int numBs = programSix.count(fileName, 'b');
            int numCs = programSix.count(fileName, 'c');

        } catch (Throwable e) {
            e.printStackTrace();
        }
    }
}

So now my code properly gives the output: giving the number of times the characters 'a' 'b' and 'c' appeared in my .txt file. Now what is the best way to read the same .txt file and give out three different letters in a output.txt file and the number of times they occurred?

Maybe an exception is happening...but you could answer this question yourself by adding a breakpoint to your code and _debugging_ it. — Tim Biegeleisen, Jun 19 '17 at 06:14
@User4392892 the output it gives is just a on the first line, b on the second line and thats it. — New2AllThis, Jun 19 '17 at 06:15
Okay I just changed around the code a bit, and now it gives the output of every 'a' or 'A' that appeared in my .txt file — New2AllThis, Jun 19 '17 at 06:18
Your program won't even compile - `Program6` != `ProgramSix` — MadProgrammer, Jun 19 '17 at 06:19

You are using the wrong class

see

class  ProgramSix

vs

Program6 program6 = new Program6();

You are absolutely right, thank you. But will this make difference in the output? – New2AllThis Jun 19 '17 at 06:20
If this code compiles then at some stage you must have had a class called `Program6` - it is not the above code – Scary Wombat Jun 19 '17 at 06:21
I changed them and got the correct output, thank you for recognizing my dumb mistake – New2AllThis Jun 19 '17 at 06:21
That's great, please upvote and/or accept my answer – Scary Wombat Jun 19 '17 at 06:22
Will do I gotta wait like six minutes first tho, I also have another part to my question that I need to add maybe you can take a look at it – New2AllThis Jun 19 '17 at 06:24
I just updated my post if you can take a look at it again. Thank you – New2AllThis Jun 19 '17 at 06:31
what is wrong with the way that you are doing it? – Scary Wombat Jun 19 '17 at 06:35
There is nothing wrong with the way I am doing it, its just its an assignment and I need to also output the same answer to an output.txt file if you know how to do that – New2AllThis Jun 19 '17 at 06:43
try spending a couple of seconds to search for it - https://stackoverflow.com/questions/2885173/how-do-i-create-a-file-and-write-to-it-in-java – Scary Wombat Jun 19 '17 at 06:44
I have added the code that they suggested I am not sure what to put in my .out.println() that gives the output to the .txt file. Like I am not just posting the letters I need it to read my .txt file – New2AllThis Jun 19 '17 at 06:46
why don't you open a new question - if you have one – Scary Wombat Jun 19 '17 at 06:47
I would but I'm pretty sure I won't be able to because everyone down rated this and put my question on hold. – New2AllThis Jun 19 '17 at 06:48
