Java file search

hi Im having some problems figure out why my code doesent work

Write a program Search that searches all files specified on the command line and prints out all lines containing a keyword. For example, if you call

java Search Buff code.txt address.txt Assignment.java

then the program might print

code.txt: Buffer style lunch will be available at the

here is my code


class Search {


    public static void main(String args[]){


        BufferedReader br = null;

        String pattern, s;

        int numInputFiles, ctr;


        numInputFiles = args.length - 1;

        pattern = new String ();

        s = new String ();


        pattern = args[0];    

        for (ctr = 0; ctr < numInputFiles; ctr++){

            try {

                br = new BufferedReader (new FileReader (args[ctr+1]));

                s = br.readLine ();

            }catch (Exception e) {

                System.out.println (e);

            }

            

            while (s!=null) {

                if( s.indexOf (pattern) >= 0) {

                    System.out.print(args[ctr+1] + ": ");

                    System.out.println (s);

                }    

            

                try {

                    s = br.readLine ();

                } catch (Exception e) {

                    System.out.println (e);

                }

            }

        }

        try{

            br.close();

        } catch(Exception e){

            System.out.println(e);

        }    


    }

}
