Ho seguito il tuo consiglio e ho corretto in questo modo:
Esempio.java >> Esempio.class
codice:
// Demonstrate text alignment.
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
/* <title>Text Layout</title>
<applet code="Esempio" width=200 height=200>
<param name="text" value="Output to a Java window is actually quite easy.
As you have seen, the AWT provides support for
fonts, colors, text, and graphics. <P> Of course,
you must effectively utilize these items
if you are to achieve professional results.">
<param name="fontname" value="Serif">
<param name="fontSize" value="14">
