You noticed that you cannot see the applet while the page is loading. What's the reason for it?

When a Java applet is embedded in a web page, the browser's plugin/JVM must first load the applet's class file(s), instantiate the Applet object, and call its lifecycle methods (init(), which reads the values declared in the HTML) before the applet can paint anything on screen. Until that initialization — including registering/reading all its declared parameters — completes, there is nothing for the JVM to render, so the applet area appears blank while the page is still loading. Of the given options, this initialization-before-render process is the only one that actually explains a temporary, loading-phase invisibility. Incorrect file permissions or an unregistered/protected applet would typically produce a persistent failure or a security exception rather than a delay that resolves once the page finishes loading, so they don't fit the "while the page is loading" framing of the question.
