A good answer might be:

Yes. Children of the same parent have their parent's characteristics in common, but each child has additional methods and variables.

AWT Hierarchy

The Java AWT (Abstract Windowing Toolkit) contains the fundamental classes used for constructing GUIs. The abstract Component class is the base class for the AWT. Many other AWT classes are derived from it. (We will not look at most of these classes).

Button, Canvas, and Container are some AWT classes derived from Component.

The JComponent class is derived from Container and is one of the base classes of Swing. The JFrame class is derived from the AWT Frame class. It is usually the main container for a GUI application.

The JApplet class (derived from the AWT Applet class) is sometimes used for Web programming, but the Applet class is more frequently used.
