Need help with adding multiple of the same image to a JFrame

[ndsmith20]

Hi, Im trying to set up a program that will add a determined number of .gif images to a JFrame (using GridLayout to add each one to seperate line) and then will eventually have them race across the screen. For some reason my images and program will not appear when i run it. This is my code:

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

public class Races extends JFrame{
   //attributes
   private int racers;
   private JLabel jlImage;
   private Timer timer;
   int w = 1;
   
   
   public Races(int _racers){
      racers = _racers;
      setTitle("Off to the Races - Nicholas Smith");
      setLayout(new GridLayout(0,1));
      setLocationByPlatform(true);
      setLocationRelativeTo(null);
      
      while(0 <= racers){
         final RacerProgress rp =  new RacerProgress();
         add(rp);
      }
      pack();
      setVisible(true);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   }
   
   public class MyTimerListener implements ActionListener{
      public void actionPerformed(ActionEvent ae){
         Point loc = jlImage.getLocation();
         loc.translate(((int)(Math.random()*100)),0);
         jlImage.setLocation(loc);
         repaint();
      }
   }

   
   class RacerProgress extends JPanel implements Runnable{
      
      public RacerProgress(){
         Icon image = new ImageIcon("races.gif");
         jlImage = new JLabel(image);
         jlImage.setBounds(0,0,66,45);
         jlImage.setDoubleBuffered(true);
         add(jlImage);
      }
      
      public void run(){
         
      }
   }
   
   public static void main(String[] args){
      Races racetime = new Races(6);
   }

}

I am not receiving any error when running or compiling it is just sitting there. Thank you so much for the help.

Is the program executing an infinite loop that could be keeping it from doing what you want it to do?

[ndsmith20]

yes it was an infinite loop so i do have the pictures showing now...thank you!

[ndsmith20]

i do need assistance with one more thing...i have the pictures appearing and the finish line is showing as well...now i need the images to all be on the left hand side. Is there any way to do this i tried aligning left.

public class Races extends JFrame{
   //attributes
   private int racers;
   private JLabel jlImage;
   private Timer timer;
   int w = 1;
   
   
   public Races(int _racers){
      racers = _racers;
      setTitle("Off to the Races - Nicholas Smith");
      setLayout(new GridLayout(0,1));
      setLocationByPlatform(true);
      setLocationRelativeTo(null);
      setSize(600, 600);
      
      while(0 <= racers){
         final RacerProgress rp =  new RacerProgress();
         add(rp);
         rp.setAlignmentX(Component.LEFT_ALIGNMENT);
         System.out.println("running");
         racers--;
      }
      //pack();
      setVisible(true);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   }
   
   public class MyTimerListener implements ActionListener{
      public void actionPerformed(ActionEvent ae){
         Point loc = jlImage.getLocation();
         loc.translate(((int)(Math.random()*100)),0);
         jlImage.setLocation(loc);
         repaint();
      }
   }
   
  public void paint(Graphics g) {
        super.paint(g);  
        Graphics2D g2 = (Graphics2D) g;
        Line2D lin = new Line2D.Float(500, 100, 500, 600);
        g2.draw(lin);
    }

   
   class RacerProgress extends JPanel implements Runnable{
      
      public RacerProgress(){
         Icon image = new ImageIcon("races.gif");
         jlImage = new JLabel(image);
         jlImage.setBounds(0,0,66,45);
         jlImage.setDoubleBuffered(true);
         add(jlImage);
      }
      
      public void run(){
         
      }
   }
   
   public static void main(String[] args){
      Races hw4 = new Races(6);
   }

}

I suggest you take some time to study layout managers.

Lesson: Laying Out Components Within a Container (The Java™ Tutorials > Creating a GUI With JFC/Swing)

A Visual Guide to Layout Managers (The Java™ Tutorials > Creating a GUI With JFC/Swing > Laying Out Components Within a Container)

Because any "how do I get positioning XYZ?" requirements are solved by applying either the right layout manager, or a combination of the right layout managers by nesting components. I tend to subdivide my GUI with a sequence of BorderLayout components and I tend to use either FlowLayout or BoxLayout at the "lowest level".

normally in this instance i would use a borderlayout and then put in the west but for this problem i have to use a grid layout...i guess i could use border layout and then create a panel with grid layout for the west panel...thank you...i guess i just needed to think it out more
