How to find a word in multiple text files ?

[maral]

Hi every one, this is my first post here!

I'm using GATE toolkit for information retrieval and text analysis, but i really need java for some parts.

I have managed to find a specific word in one text file, but i need to look for a specific word, in multiple text files. all of the files are ".txt" and they are in the same folder but each of them with different names. I have written the following code: but i receive an error that i don't know how to solve:

import java.io.*;
import java.util.Scanner;

public class Find {

    public static void main(String s) throws IOException {
        int count =0;
        String srcDir = s;
        File folder = new File(srcDir);
        File[] listOfFiles = folder.listFiles();
        if (listOfFiles.length > 0) {
            for (int i = 0; i < listOfFiles.length; i++) {
                if (listOfFiles[i].isFile()) {
                    Scanner a = null;
                    a = new Scanner(new BufferedReader(new FileReader(srcDir + listOfFiles[i].getName())));
                while (a.hasNext()){
                String words = a.next();
                if (words.equals("good")){
                   count++;
                }

            }
    System.out.println("the total is:" + count);

        }
    }
    }
    }
    }

and this is the error that i get:

java.lang.NoSuc hMethodError: main
Exception in thread "main"

I would appreciate any helps and comments.

Change your main function to

public static void main(String[] s)

Dheeraj, thanks for your comment.
with few more changes, it helped to solve my problem.

Yes. You should also change following lines.

String srcDir = s;

Also avoid hard coding like, "if word equals good",etc. try to write a generic program.
