Search for a word and return all the lines (row) from the text file..

Question

Hi all,
I need a help on how to search a string from the text file and returns all the lines (rows) where the searched string are found. I have included the code, it finds the indexof the string but it does not return the entire line. I would appreciate your any help.
public class SearchWord
     public static void main(String[] args){
     //Search String
     String searchText = "man";
     //File to search (in same directory as .class file)
     String fileName = "C:\\Workspace\\MyFile.txt";
     //StringBuilder allows to create a string by concatinating
     //multiple strings efficiently.
     StringBuilder sb =
     new StringBuilder();
     try {
     //Create the buffered input stream, which reads
     //from a file input stream
     BufferedInputStream bIn =
     new BufferedInputStream(
     new FileInputStream(fileName));
     //Holds the position of the last byte we have read
     int pos = 0;
     //Holds #of available bytes in our stream
     //(which is the file)
     int avl = bIn.available();
     //Read as long as we have something
     while ( avl != 0 ) {
     //Holds the bytes which we read
     byte[] buffer = new byte[avl];
     //Read from the file to the buffer
     // starting from <pos>, <avl> bytes.
     bIn.read(buffer, pos, avl);
     //Update the last read byte position
     pos += avl;
     //Create a new string from byte[] we read
     String strTemp =
     new String(buffer);
     //Append the string to the string builder
     sb.append(strTemp);
     //Get the next available set of bytes
     avl = bIn.available();
     catch(IOException ex) {
     ex.printStackTrace();
     //Get the concatinated string from string builder
     String fileText = sb.toString();
     int indexVal = fileText.indexOf(searchText);
     //Displays the index location in the file for a given text.
     // -1 if not found
     if (indexVal == -1)
          System.out.println("No values found");
     else
          System.out.println("Search for: " + searchText);     }
}

Hi, you can use servlet class and use this method to get the whole line of searched string. You can override the HttpServlet to treat that class as servlet.
public class ReportAction extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//write your whole logic.
BufferedReader br = new BufferedReader(new FileReader("your file name"));
String line = "";
while(line = br.readLine() != null) {
    if(line.contains("your search string")) {
        System.out.println("The whole line, row is :"+line);
}
