Multiple Choice

When an application uses many components, rather than deriving just one class from the JFrame class, it is often better to encapsulate smaller groups of related components and their event listeners into their own class. A commonly used technique to do this is:

• B) To extend a class from the JComponent class to contain other components and their related code
• C) To extend a class from the JPanel class to contain other components and their related code
