Regular Expression -- Did Not Find Successfully

Question

I ran a test: to find a piece of text "Bill" in a letter. This letter is in MS Word format. I am certain that "Bill" is in the letter. My simple java program compiled and ran (java MatchingText). However, I did not get "A match is found", which is the message specified in the System.out.println, to the console.
Here is my code:
import java.util.regex.*;
import java.io.*;
public class MatchingText {
public static void main(String[] args) throws Exception {
File fin = new File("c:/javaprj/letter.doc");
//Open an input stream
FileInputStream fis =
new FileInputStream(fin);
BufferedReader in = new BufferedReader(
new InputStreamReader(fis));
String input = "Bill";
// Create a pattern to match input
Pattern p = Pattern.compile("input");
Matcher m = p.matcher(input);
if (m.find()) {
System.out.println("A match is found"); }
in.close();
Could someone points out my mistake? Thanks.

Answer 1

There were mistakes in my program. I fixed some of the mistakes and I could see improvements in the output. Yet, I am not quite there:
when there is no match in the source document, the code outputs "Found A Match" twice to the console.
When there is "one" match in the source document, the code outputs "Found A Match" three times to the console.
When there are "two" matches in the source document, the code outputs "Found A Match" four times to the console.
When there are "three" matches in the source document, the code outputs "Found A Match" five times to the console.
and so on.
Just wonder where those two extra "Found A Match" come from.
code:
import java.util.regex.*;
import java.io.*;
public class MatchingText {
public static void main(String[] args) throws Exception {
//String provided by the user
String userInput = "Bill";
File fin = new File("c:/javaprj/letter.doc");
//opens a bufferdReader to read lines
BufferedReader in=new BufferedReader(new FileReader(fin));
try {
while((userInput = in.readLine()) !=null) {
//pattern in the source document
String targetText = "Bill";
//Create a pattern to match input
Pattern p = Pattern.compile(targetText);
//To find a match in each line
Matcher m = p.matcher(userInput);
while (m.find()) System.out.println("Found A Match");
catch(IOException e){System.out.println("Error occurred while reading!");}
//close the streams
finally {
try {
in.close();
catch(IOException e){System.out.println("closing file exception");}
