Dimension dimjf = jframe. getSize ();
Int width = (dim. width-dimjf. width)/2;
Int height = (dim. height-dimjf. height)/2;
Jframe. setLocation (width, height );
Equivalent to: jframe. setLocationRelativeTo (null );
Note: The window size must be set before the window position; otherwise, the window cannot be centered.

I saw folders in other projects and moved the images to other projects.

JFrame structure: RootPane, LayeredPane, ContentPane, Classpath;

I. JFrame structure:

JFrame has four layers of structure: Frame, Rootpanel, Compenetpanel, and Classpanel. I don't understand it either. I will be working on it later.
