请问以下这个程序图片为什么出不来，没有报任何错。就是图片出不来。


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

public class JSplashWindow extends JWindow implements Runnable {
Thread splashThread=null;

boolean bool = true;
JPanel splash = null;
URL url = null;

public JSplashWindow() {

splash = new JPanel(new BorderLayout());
url = getClass().getResource("/images/winter.jpg");
setContentPane(splash);

Dimension screen = getToolkit().getScreenSize();
pack();
setLocation((screen.width - getSize().width) / 2,(screen.height - getSize().height) / 2);

}

public void start(){
this.toFront();
splashThread=new Thread(this);
splashThread.start();
}

public void run(){
JLabel label = new JLabel(new ImageIcon(url));

try {
setVisible(true);
while(bool) {

if(url != null){
splash.add(label,BorderLayout.CENTER);
}
Thread.sleep(500);
splash.remove(label);
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
Thread.sleep(500);

}

} catch (Exception ex) {
ex.printStackTrace();
}

}

static void showFrame(String title){
JFrame frame = new JFrame(title);
frame.setSize(400,300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height) {
frameSize.height = screenSize.height;
}
if (frameSize.width > screenSize.width) {
frameSize.width = screenSize.width;
}
frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
frame.setVisible(true);
}

public static void main(String[] args) {
showFrame("Demo splash window");
JSplashWindow splash = new JSplashWindow();
splash.start();
}
}

谢谢3楼，可是你给我的代码依然不能察看到图片。
是这样的 我把run方法中的
if(url != null){
splash.add(label,BorderLayout.CENTER);
}
这段代码放到JSplashWindow的构造方法里面就能够查看到图片
但是像这样放到run中就无法查看到图片。

你没有把splash加到frame上吧

即使图片路径弄好了你这个程序加载不了图片，是程序的问题
package com;//com文件夹放有java，class文件，还有放有winter.jpg图片的images文件夹

URL url = getClass().getResource("/images/winter.jpg");

if(url != null){
splash.add(new JButton(new ImageIcon(url)),
BorderLayout.CENTER);
}
/* progress = new JProgressBar(1,100);
progress.setStringPainted(true);
progress.setBorderPainted(false);
progress.setString("Program is Now Loading...");
progress.setBackground(Color.white);

pack();
setLocation((screen.width - getSize().width) / 2,

}
}
catch (Exception ex) {

}
dispose();
}

frame.setSize(640,480);
