hi leute,
ich brauche hilfe bei einem applet für das sortierverfahren bubblesort.
mein problem ist, dass ich nicht weiß was ich bei der ausgabe (draw()-methode) falsch mache, diese gibt einfach nicht meinen string (liste) aus…
hier mein quellcode, ide ist netbeans 7:
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.lang.reflect.InvocationTargetException;
