Per l'esattezza, se provo a compilare questo :
package applet;

import java.applet.Applet;
import java.awt.Graphics;

public class StringApplet extends Applet
{ public void paint(Graphics g) {
g.drawString("ciao mamma guarda come mi diverto", 10, 10);}}

su eclipse lo esegue correttamente, ma su terminale mi da questi errori:
