Pattern Matching to string problme

Ok well the code here works fine for accutally finding the patterns from the file that I am using, the problme is I want to print out the entire string that the pattern is in. it is a text file with this set up
Book Title blah: Author someguy: Num of pages 13: Price 6532.00;
and that is over and over for each boot. Whats printing off is just saying it got a match and where that match is. How can I print off the entire string that it is in?
Thanks for any help

Code Java:

---

public static void search()
   {
       try
       {
            FileInputStream fis = new FileInputStream("Book-text.dat");
            BufferedInputStream bis = new BufferedInputStream(fis);
            DataInputStream dis = new DataInputStream(bis);
            String sStr;
            System.out.println("Enter your search");
            Scanner sScan = new Scanner(System.in);
            sStr = sScan.nextLine();
            Pattern pat = Pattern.compile(sStr, Pattern.CASE_INSENSITIVE);
            System.out.println("Your searching for " + pat);
 
            System.out.println(dis.available());
            StringBuilder sb = new StringBuilder();
            //put file into string builder
 
            while(dis.available()!= 0)
            {
                sb.append(dis.readChar());
 
            }
            System.out.println("Before Match " + sb.length());
            //Stores the file into one string matcher
            String fileText = sb.toString();
 
 
 
            // this statement reads the line from the file and print it to
              // the console.
 
                Matcher mat = pat.matcher(fileText);
                    while(mat.find())
                        {
                            String result = mat.toString();
                            System.out.println(result.trim());
                        }
 
                if(mat.find()==false)System.out.println("No Matcher Found");
 
 
            // dispose all the resources after using them.
            fis.close();
            bis.close();
            dis.close();
 
       }catch(IOException e)
       {e.printStackTrace();}
       catch(PatternSyntaxException e)
       {e.printStackTrace();}
 
   }

If you can figure out where the substring is located, why can't you just use the subsring method to extract it?

It might help if you gave us a few more examples of desired input and output.

I used the sub string and that worked fine thanks for that.
