Creating a JFrame
The JFrame class provides two primary constructors: one for creating a frame without a title
and one for creating a frame with a title. There are two additional constructors for creating
frames with a specialized GraphicsConfiguration .

public JFrame()
JFrame frame = new JFrame();

public JFrame(String title)
JFrame frame = new JFrame("Title Bar");

public JFrame(GraphicsConfiguration config)
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gsd[] = ge.getScreenDevices();
GraphicsConfiguration gc[] = gsd[0].getConfigurations();
JFrame frame = new JFrame(gc[0]);

public JFrame(String title, GraphicsConfiguration config)
GraphicsConfiguration gc = ...;
JFrame frame = new JFrame("Title Bar", gc);
