Which Applet class method displays results on screen?
Show answer Hide answer
Answer: A. paint() method
Explanation
The paint method is utilized within graphical applets to render visual components on screen. It is automatically invoked by the system whenever the user interface requires redrawing. The correct choice identifies the standard rendering callback method for visual applet displays. Applets are small client-side applications that run inside web browsers using virtual machines. Graphics contexts passed to paint methods provide drawing primitives for lines, shapes, and text. Graphical user interfaces rely on event-driven callback methods to handle screen updates.
Legacy web applications used applet rendering methods to display interactive animations and charts. Understanding graphical callbacks helps developers manage custom user interface component rendering. Modern web standards have largely replaced applets with HTML5 and native browser technologies. The main method serves as the standard entry point for standalone console applications. The run method is used by threads to execute concurrent tasks rather than render graphics. DrawString is a drawing utility method called within paint rather than the container method.
