			try{
				Thread.sleep(5000);
				if(bud!=null)
				{
				  bud.play();
				}
				
			}
			catch(InterruptedException e)
			{
				System.out.println("出错了...");
			}
		}
	}
	
	public void paint(Graphics screen)
	{
		Graphics2D aa=(Graphics2D)screen;
		aa.drawString("play...", 10, 10);
	}
}

运行正常，但是就是没有声音？
为什么会这样？

打声音文件放到getCodeBase()目录下试试
