Please help me understand. What is the difference between getContentPane() and JPanel? As far as I know, getContentPane() is a method which does the same things like JPanel, like they are being used for including some components like "buttons", "radio buttons", etc?

Basically it follows an hierachy:

JFrame > JPanel > ContentPane > other elements

The JPanel is almost the same thing as a content pane, but rather then an object itself, it's treated more like an attribute.

You should check out the official documentation for JFrame at https://docs.oracle.com/javase/7/docs/api/javax/swing/JFrame.html
