关于设置JFrame大小

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
// 获取屏幕的边界
Insets screenInsets = Toolkit.getDefaultToolkit().getScreenInsets(
this.getGraphicsConfiguration());
// 获取底部任务栏高度
int taskBarHeight = screenInsets.bottom;
// 计算出MonitorFrame应当的高度
int monitorFrameHeight = screenSize.height - taskBarHeight;
this.setSize(screenSize.width, monitorFrameHeight);
// this.setExtendedState( MonitorJFrame.MAXIMIZED_BOTH );
this.setVisible(true);
