I have two JLabels with different lenght of text. One JLabel is below
the other. I'd like to get the two "colons" in them to line-up
vertically.

I tried padding one with "space" characters, but that didn't line up
perfectly. My guess is that certain characters have different
widths.

(I tried the align vertical and horizontal properties, etc but they
didn't work.)

Eg, In the below text of two JLabels, the addition of a space
character didn't line up the two colons.

Label1 My First Name: Label2 Last Name:

Thanks,

Here are two examples;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;

public class test2 extends JPanel {
     public test2() {
         super(new GridBagLayout());

         GridBagConstraints c = new GridBagConstraints();
         c.gridx = 1; c.fill = GridBagConstraints.HORIZONTAL;
         c.weightx = 1.0;

         Border b = BorderFactory.createLineBorder(Color.BLUE,1);

         // both labels will be the same size and the text will
         // be right aligned
         JLabel l1 = new JLabel("My First Name:",JLabel.RIGHT);
         l1.setBorder(b);
         JLabel l2 = new JLabel("Last Name:",JLabel.RIGHT);
         l2.setBorder(b);

         add(l1,c);
         add(l2,c);

         setPreferredSize(new Dimension(100,75));
     }

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
                 f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                 f.setLayout(new GridBagLayout());
                 f.add(new test2());
                 f.setSize(400,300);
                 f.setVisible(true);
             }
         });
     }
}

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;

public class test extends JPanel {
     public test() {
         // single label with two lines of text right aligned with css
         JLabel l = new JLabel(
          "<html><div style=float: right;>This is very long:<br>This
short:");
         l.setBorder(BorderFactory.createLineBorder(Color.BLUE,1));
         add(l);
     }

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
                 f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                 f.add(new test(),BorderLayout.CENTER);
                 f.setSize(400,300);
                 f.setVisible(true);
             }
         });
     }
}
