text-it Weihnachtsgimmick

1. Einfach nachfolgenden Code in einen JAVA Editor kopieren – z.B. Online Compiler: jdoodle.com
2. Compiler ausführen (Execute) und schon leuchtet das Weihnachtsbäumchen in den Ergebnissen auf.
3. Bäumchen in eine Word-Datei kopieren, Schrift auf Lucida Console (9 pt) ändern und weiterschmücken.

Tipp für Fortgeschrittene: text-it durch Ihren (Firmen-)Namen ersetzen (7 Zeichen) – gleich wird es persönlicher.
Tipp für Tüftler: Für die kürzere, längere oder zusammengesetzte Eingabe von Namen Zeile 8 fixen.

Frohes Schaffen!
