Hey Ujjal,
I know it's late and I don't know if you're still having this issue but maybe this can be helpful to the next person who has it. As was already said, I think you should probably consider doing this project as an application rather than an applet to avoid file access permission problems. That said, here's how I would do it (since no one has answered your question directly):
First this class should extend JFrame or some other window class
Next create a file object (it's static so it can be accessed by anonymous classes later):
private static File myFile = null;Then, inside the appropriate method (probably something like init() or main()), make the button and give it some functionality with an anonymous MouseListener:
JButton myBrowseButton = new JButton("Browse");
myBrowseButton.addMouseListener(new MouseAdapter(){
    // an anonymous MouseAdapter
    public void mouseClicked(MouseEvent e){
        ...now in here you'll want the code to make a JFileChooser in a dialog window
        // create a dialog window
        final JDialog myChooserDialog = new JDialog();
        myChooserDialog.setTitle("Browse");
        // an anonymous JFileChooser
        JFileChooser myFileChooser = new JFileChooser(PATH){
            // an anonymous instantiator to set the text of the select button
            { setApproveButtonText("Select"); }
            // what to do when the user clicks select
            public void approveSelection(){
                // you might want to make sure the selected file is valid before this step
                myFile = getSelectedFile();
                myChooserDialog.dispose();
            // what to do if the user clicks cancel
            public void cancelSelection(){ myChooserDialog.dispose(); }
        ...add the chooser to the dialog and make it visible
        myChooserDialog.add(myFileChooser);
        myChooserDialog.setVisible(true);
        myChooserDialog.pack();
});Now add the button to the frame and make it visible
add(myBrowseButton);
setVisible(true);
pack();A few notes:
1) Replace the word PATH with the path to the directory you want to browse (e.g. "." the current working directory)
2) Make sure all of that code except for private static File myFile = null; goes into a method and isn't just floating around
3) If ANY of this was confusing then go D.A.F.T (Do A Fecking Tutorial!)
good luck!
