E:SourceAndDocZAX>
源码如下：
public class Test {

  /**
   * Constructor
   */
  public Test(Zax zax,String[] args) {
    Frame frame = new TestFrame(zax,args);
    //Center the window
    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.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } });
    frame.setVisible(true);
  }

  /**
   * main
   * @param args 传送文件的目标IP地址
   */
  public static void main(String[] args) {
    try  {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    }
    catch (Exception e) {
      e.printStackTrace();
    }

    new Test(new Zax(),args);
  }
}

请高手指教，不胜感激！

E:SourceAndDocZAX>java Test
改为
E:SourceAndDoc>java ZAX.Test0D

是因为找不到Zax这个类把
==================
别忘给分啊:))))))

为什么一个包都不用import的，至少也应该有javax.swing.*、java.awt.*和java.awt.event.*吧？
否则怎么出Frame出来？

是不是沒將SystemLookAndFeelClass所在的包import
