Reading to a certain point in a txt file

Question

I am trying to read to a certain point in a txt file. I want it to read until it reaches say password, then check to see if the text is the same as say "bob" an dif not go on to the next password. This is what i have so far:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class Read extends JFrame implements ActionListener {
     private JButton act;
     private JTextArea show;
     public Read() {
          setSize(new Dimension(300, 300));
          act = new JButton("GO");
          act.addActionListener(this);
          show = new JTextArea("push the button");
          JPanel pane = new JPanel(new GridLayout(0, 1));
          getContentPane().add(act, BorderLayout.NORTH);
          getContentPane().add(show);
     public void actionPerformed(ActionEvent e) {
          try {
               BufferedReader reading = new BufferedReader(new FileReader("dat.u.txt"));
               String file;
               while ((file = reading.readLine()) != null) {
                    show.setText("");
                    show.append(file + " finished append");
          catch (FileNotFoundException ioe) {
               show.setText("error finding the file name");
          catch (IOException ioe) {
               show.setText("IO Error");
     public static void main (String args[]) {
          new Read().setVisible(true);
}P.S I gave this is just a test file to test. I also gave examples at the top. Thanx for the help!!

Answer 1

What are you doing with file everytime it reads a line? Displaying it in the JTextArea. You do no checking to see if the line read contains what you are looking for.
if(file contains what I am looking for) {
    //process file
    break;
}BTW, if it is a password you are searching for, displaying it in a text area for all the world to see is not a good idea.
