java 获取屏幕的分辩率

        Rectangle windowSize = new Rectangle();
        Dimension scrSize = Toolkit.getDefaultToolkit().getScreenSize();
        Insets scrInsets = Toolkit.getDefaultToolkit().getScreenInsets(GraphicsEnvironment.getLocalGraphicsEnvironment()
                .getDefaultScreenDevice().getDefaultConfiguration());

        //获取屏幕可以利用的width和height
        //windowSize.setBounds(scrInsets.left, scrInsets.top, scrSize.width - scrInsets.left - scrInsets.right, scrSize.height - scrInsets.top - scrInsets.bottom);

        //获取屏幕的分辨率
        windowSize.setBounds(scrInsets.left, scrInsets.top, scrSize.width, scrSize.height);
        System.out.println("The desktop resolution is : " + windowSize);
