modifying a program to make second argument

hey guys, i have written a program which searches through a file in
order to ouput the number of characters, words and lines contained in a
certain file.. this works fine but i was hoping to take this one step
further.. in order to output the number of occurences of a word and
also the number of lines that word appears on..

for instance if i entered 'java WordCount bob.txt the' then the output
would include the number of occurences of the word 'the' and also the
number of lines which contain 'the'..

the code i have so far
is:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

import java.io.*;
public class WordCount {
    private static void count(String name, BufferedReader in) throws
    IOException {
        long numLines = 0;
        long numWords = 0;
        long numChars = 0;
        String line;
        do {
            line = in.readLine();
            if (line != null)
            {
                numLines++;
                numChars += line.length();
                numWords += countWords(line);
            }
        }
        while (line != null);
        System.out.println(name + "\t" + numLines + "\t" +
            numWords + "\t" + numChars);
    }

    /**
     * Open file, count its words, lines and characters
     * and print them to standard output.
     * @param fileName name of file to be processed
     */
    private static void count(String fileName) {
        BufferedReader in = null;
        try {
            FileReader fileReader = new FileReader(fileName);
            in = new BufferedReader(fileReader);
            count(fileName, in);
        } catch (IOException ioe) {
            ioe.printStackTrace();
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        }
    }

    /**
     * Count words, lines and characters of given input stream
     * and print them to standard output.
     * @param streamName name of input stream (to print it to stdout)
     * @param input InputStream to read from
     */
    private static void count(String streamName, InputStream input) {
        try {
            InputStreamReader inputStreamReader = new InputStreamReader(input);
            BufferedReader in = new BufferedReader(inputStreamReader);
            count(streamName, in);
            in.close();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }

    /**
     * Determine the number of words in the argument line.
     * @param line String to be examined, must be non-null
     * @return number of words, 0 or higher
     */
    private static long countWords(String line) {
        long numWords = 0;
        int index = 0;
        boolean prevWhitespace = true;
        while (index < line.length()) {
            char c = line.charAt(index++);
            boolean currWhitespace = Character.isWhitespace(c);
            if (prevWhitespace && !currWhitespace) {
                numWords++;
            }
            prevWhitespace = currWhitespace;
        }
        return numWords;
    }

    public static void main(String[] args) {
        if (args.length == 0) {
            count("stdin", System.in);
        } else {
            for (int i = 0; i < args.length; i++) {
                count(args[i]);
            }
        }
    }
}

any ideas how to modify this code in order to produce the new outputs?

Thank you all for your help
