Simulation
Java offers many different tools and features. Some of these are absolutely necessary, and some are merely convenient. For example, because a switch statement can be realized with nested if-then-else statements, a switch statement is a convenience, not a necessity. Not all GUI features are necessary. Explain how you might simulate the component in column A with the corresponding components and objects in column B.
A | B |
A button | A label and a mouse listener |
An input dialog box | A text field and a listener |
A confirmation dialog box | A button and a listener |
A radio button | Buttons, labels, and listeners |
A checkbox | Buttons, labels, and listeners |
