I want the path to be displayed onto the text box on t开发者_C百科he side of browse button.

You should take a look at Sun's tutorial for the JFileChooser API. This will give you pretty much everything you need to accomplish what you're trying to do.

...
public String fileID;
public JTextField txtField; //Assume this is the text box you placed beside browse button
public JButton btnBrowse = JButton("Browse");

public void actionPerformed(ActionEvent e)
{
    if (e.getSource() == btnBrowse)
    {
        chooser = new JFileChooser(new File(System.getProperty("user.home") + "\\Downloads")); //Downloads Directory as default
        chooser.setDialogTitle("Select Location");
        chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        chooser.setAcceptAllFileFilterUsed(false);

        if (chooser.showSaveDialog(this) == JFileChooser.APPROVE_OPTION)
        { 
            fileID = chooser.getSelectedFile().getPath();
            txtField.setText(fileID);
        }
    }
}
