请教高手AWT的图片显示问题
import   java.awt.*;
import   java.awt.event.*;
public   class   DrawImage
{
public   static   void   main(String   []   args)
{
Frame   f=new   Frame( "IT   communication 's   net ");
Image   img=f.getToolkit().getImage( "c:\\test.gif ");
f.getGraphics().drawImage(img,0,0,f);
f.setSize(500,500);
f.setVisible(true);
f.addWindowListener(new   WindowAdapter()
{
public   void   windowClosing(WindowEvent   e)
{
e.getWindow().setVisible(false);
((Window)e.getComponent()).dispose();
System.exit(0);
}
});
}
}

为什么用JCreator运行时出现
Exception   in   thread   "main "   java.lang.NullPointerException         at   DrawImage.main(DrawImage.java:9)

不用加C盘。。直接放在你的.java目录下，就可以了。
