Needing Help in my code

[NeedHelp11]

Hi everybody :),

I wrote this code to read data from a file and then display it in textfield in GUI.
But the problem was in displaying the GUI. It is run the application first and then GUI appear with last number that read from the file.
I want the GUI appear first and then the application read from the file and update the values until it finished.

This is the code
import java.awt.BorderLayout;
import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

import javax.swing.JLabel;
import javax.swing.JTextField;

import javax.swing.WindowConstants;
import javax.swing.SwingUtilities;

}




Thanks in Advance for helping

Move you data collection code into a seperate method, then call it in your constructor after your initGUI call. You will also need to move your setText call so that it is done after the data collection as well. Your main method could look something like this:


public static void main(String[] args)
{
new NewJFrame();
}


And you constructor something similar to:


public NewJFrame()
{
super();
initGUI();
collectData();
}

It is worked
but I want the program to read from the file while it is running.
I want the value in the textfield to change (updated) while the program is running
like if we have data that change and to be update each time.
The program now is reading from the file and display the last number in text file.

I hope you understand me.
