Java获得屏幕分辨率

Java获得屏幕分辨率源代码如下：

public class Screen
{
    public static void main(String[] args)
    {
           int screenWidth=((int)java.awt.Toolkit.getDefaultToolkit().getScreenSize().width);
           int screenHeight = ((int)java.awt.Toolkit.getDefaultToolkit().getScreenSize().height); 
           System.out.println(screenWidth+""+screenHeight);
     }
}
class ScreenSize
{
   private int screenWidth;
   private int screenHeight;
   public  void setScreenWidth(int screenWidth)
    {
        this.screenWidth=screenWidth;
    }
   public void setScreenHeight(int screenHeight)
  {
       this.screenHeight=screenHeight;
   }
   public int getScreenWidth()
   {
          setScreenWidth((int)java.awt.Toolkit.getDefaultToolkit().getScreenSize.width);
          return screenWidth;
    }
    public int getScreenHeight()
    {
        setScreenHeight((int)java.awt.Toolkit.getDefaultToolkit.getScreenSize().height);
          return screenHeight;
     }
}
