这段代码主要实现了一个 SplashWindow 窗口的初始化。定义了相关的面板和坐标、尺寸变量，在构造函数中获取内容面板，设置布局，计算窗口位置和大小，将面板添加到窗口并显示。

private SplashPanel SPLASHPANEL=new SplashPanel();
private int splash_x;
private int splash_y;
private int splash_w;
private int splash_h;
private Container con;

public SplashWindow()
{
con=getContentPane();
con.setLayout(new BorderLayout());

  Dimension screensize=Toolkit.getDefaultToolkit().getScreenSize();
  Dimension splashsize=SPLASHPANEL.getPreferredSize();
  splash_w=splashsize.width;
  splash_h=splashsize.height;
  splash_x=(int)((screensize.width-splash_w)/2);
  splash_y=(int)((screensize.height-splash_h)/2);
  con.add(SPLASHPANEL,BorderLayout.CENTER);
  setBounds(splash_x,splash_y,splash_w,splash_h);
  show();
}
