How to insert a vertical JSeperator on a page between two data categories using designgridlayout?

For example, I want to insert data into two categories on a page.

USER         |             PASSWORDS

user1        |             ******

user2        |             *******

user3        |             *********

I inserted a pipe symbol to represent a vertical divider. However, the vertical separator must be continuous. Please, help.

DesignGridLayout layout= new DesignGridLayout(Panel);

JSeparator sep = new JSeparator(JSeparator.VERTICAL);

layout.row().grid(userlabel).add(passwordlabel);

You can do it...

import java.awt.GridLayout;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JSeparator;


public class PanelAdd extends JFrame {

    JPanel panelLabels, panelPasswords  ;

    JLabel [] userLabels ;
    JPasswordField [] passwordFields;

    public PanelAdd() {

        panelLabels = new JPanel();
        panelPasswords = new JPanel();  

        GridLayout panelsLayout = new GridLayout(0, 1, 0, 5);
        GridLayout mainLayout = new GridLayout(1, 2);

        panelLabels.setLayout(panelsLayout);
        panelPasswords.setLayout(panelsLayout);

        setLayout(mainLayout);

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        setSize(350, 150);
    }

    public static void main(String [] args) {

        PanelAdd add = new PanelAdd();
        add.addControls();
        add.setVisible(true);

    }

    private void addControls() {

        userLabels = new JLabel[3];
        passwordFields = new JPasswordField[3];

        panelLabels.add(new JLabel("Users"));
        panelPasswords.add(new JLabel("Passwords"));

        for ( int i = 0 ; i < 3 ; i++) {
            userLabels[i] = new JLabel("User "+i);
            passwordFields[i] = new JPasswordField();

            panelLabels.add(userLabels[i]);
            panelPasswords.add(passwordFields[i]);
        }

        add(panelLabels);
        JSeparator sep = new JSeparator(JSeparator.VERTICAL);
        add(sep);
        add(panelPasswords);

    }

}

Objects GridLayoutallow you to specify a rectangular grid into which components should be placed. Each cell in the grid is the same height as the other cells, and each width has the same width as the other cells. Components are stretched both vertically and horizontally to fill the cell.
