Example
import java.awt.Color;
import java.awt.Font;
import javax.swing.*;
import javax.swing.border.Border;
public class SwingDemo {
public static void main(String args[]) {
JFrame frame = new JFrame("Demo");
JLabel label;
label = new JLabel("This is demo label!");
label.setFont(new Font("Verdana", Font.PLAIN, 14));
label.setVerticalAlignment(JLabel.TOP);
Border border = BorderFactory.createLineBorder(Color.ORANGE);
label.setBorder(border);
frame.add(label);
frame.setSize(600,300);
