[SOLVED] How to search a text file?! Please help!

[HyperReal]

I would like to search a simple text file: for instance let's see the following is the contents of my text file...

Edward Password123
Cedrick pASSWORD321

How do I parse this so that I give my scanner object a username and it finds the respective password?  Each username and password are on seperate lines all will be divided by a " " ( a space).  How do I go about doing such a thing?

Here's what I have so far...

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40   41   42

package test; import java.io.*; import java.util.*; public class TestFileReader {     public void readFile(String fileName)     {         try         {             File file = new File(fileName);             Scanner scan = new Scanner(file);                         while (scan.hasNextLine())             {                 System.out.println(scan.nextLine());             }         } catch (FileNotFoundException e) { System.out.println("File not found."); }     }     public void writeToFile(String fileName, String Username, String Password)     {         try         {             FileWriter writer = new FileWriter(fileName, true);             writer.write("\n" + Username + " " + Password);             writer.flush();         } catch (IOException e) {}     }         public void getPassword(String fileName, String Username)     {         try         {             File file = new File(fileName);             Scanner scan = new Scanner(file);                     } catch (FileNotFoundException e) { System.out.println("File not found."); }             } }

If you're already reading the file line-by-line, you can use a string tokenizer to separate the username and password:

1   2   3   4

StringTokenizer st = new StringTokenizer("this is a test");      while (st.hasMoreTokens()) {          System.out.println(st.nextToken());      }

Output:

this
is
a
test

Just replace "this is a test" with the nextline read and you can parse out the username and password to do individual checks on them.

Really what I want to do is to have something that when it's given a username it finds that username's password...
I don't really need to separate everything out like that.

Ok... I figured it out..

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28

package test; import java.io.*; import java.util.*; public class TestFileReader {     static String getPassword( String userName )     {         try         {             BufferedReader r = new BufferedReader( new FileReader("file"));             String line = null;                         while ((line = r.readLine()) != null)             {                 String[] pair = line.split(" +");                                 if (pair[0].equalsIgnoreCase(userName))                 {                     r.close();                     return pair[1];                 }             }             return null;         } catch (IOException e) { throw new RuntimeException( e ); }     } }
