获取当前屏幕分辨率及当前窗口大小

//获取屏幕分辨率及当前窗口大小,位置居中显示
int x = this.getWidth();
int y = this.getHeight();
int screenWidth=((int)java.awt.Toolkit.getDefaultToolkit().getScreenSize().width);
int screenHeight = ((int)java.awt.Toolkit.getDefaultToolkit().getScreenSize().height); 
this.setLocation((screenWidth-x)/2, (screenHeight-y)/2-30);

//实例:
private void setWindowToScreenCenter(Window w) {
    Dimension size = w.getSize();
    Dimension scsize = Toolkit.getDefaultToolkit().getScreenSize();
    int x = (scsize.width - size.width) / 2;
    int y = (scsize.height - size.height) / 2;
    if (x < 0)
        x = 0;
    if (y < 0)
        y = 0;
    w.setLocation(x, y);
