JPanel is a pretty simple component which, normally, does not have a GUI (except when it is being set an opaque background or has a visual border). In this article, we summarize the common practices when working with JPanel in Swing. Basically, a JFrame represents a framed window and a JPanel represents some area in which controls (e.g., buttons, checkboxes, and textfields) and visuals (e.g., figures, pictures, and even text) can appear. Windows can contain/display multiple panels, although in the simplest GUIs, we will associate just one panel with a window. JPanel es una subclase de JComponent, y JComponent es una subclase de Container, por lo tanto, JPanel también es un contenedor.

JComponent is a a basic object that can be drawn. JContainer extends this so that you can add components to it. JPanel and JFrame both extend JComponent so that you can add things to them. JFrame provides a window, whereas JPanel is just a panel that goes inside a window.
