How do you make marching ants selection?

Question

Does anyone know how to produce the "marching ants" effect for selecting sections of an image/picture?
Thanks,
Everyman

Answer 1

English? How about the universal language:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MarchingAnts extends JComponent {
     public static void main(String[] args) {
          JFrame f = new JFrame("Marching Ants");
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JComponent app = new MarchingAnts("Only a test");
          f.getContentPane().add(app);
          f.setSize(200,200);
          f.setVisible(true);
     private float dashPhase;
     private String text;
     public MarchingAnts(String text) {
          setOpaque(true);
          this.text = text;
          Timer tmr = new Timer(100,null);
          tmr.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent evt) {
                    ++dashPhase;
                    repaint();
          tmr.start();
     protected void paintComponent(Graphics g) {
          super.paintComponent(g);
          Graphics2D g2 = (Graphics2D) g;
          g2.fillRect(0,0,getWidth(),getHeight());
          g2.setPaint(Color.WHITE);
          Stroke stroke = new BasicStroke(1.0f, BasicStroke.CAP_BUTT,
               BasicStroke.JOIN_BEVEL, 0.0f,
               new float[]{4, 2, 6, 2},
               dashPhase);
          g2.setStroke(stroke);
          g2.drawRect(50,50,100,100);
