Java获得屏幕分辨率

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;
}
}
