1. Liebe Forumsgemeinde,

    aufgrund der Bestimmungen, die sich aus der DSGVO ergeben, müssten umfangreiche Anpassungen am Forum vorgenommen werden, die sich für uns nicht wirtschaftlich abbilden lassen. Daher haben wir uns entschlossen, das Forum in seiner aktuellen Form zu archivieren und online bereit zu stellen, jedoch keine Neuanmeldungen oder neuen Kommentare mehr zuzulassen. So ist sichergestellt, dass das gesammelte Wissen nicht verloren geht, und wir die Seite dennoch DSGVO-konform zur Verfügung stellen können.
    Dies wird in den nächsten Tagen umgesetzt.

    Ich danke allen, die sich in den letzten Jahren für Hilfesuchende und auch für das Forum selbst engagiert haben. Ich bin weiterhin für euch erreichbar unter tti(bei)pcwelt.de.

[java] - IF-Anweisung - Falsche Anzahl an gefüllten Labels!

    Guten Tag,

    ich suche eine Methode(Funktion), die ein Array überprüft ob im ausgewählten Index ein Wert(String, Zahl,...) steht oder nicht.

    Würd mich über rasche Antworten freuen!

    mit freundlichen Grüßen,

    ----------------------------------------------------------------

    Update: Die IF-Anweisung klappt jetzt, nur leider enthält sie noch ein kleines Problem welches ich nicht finde :-(

          teamG.setText(teamSorted[7]);
          teamH.setText(teamSorted[8]);
     }
     
}
    Hoffe es ist nicht zuviel Code, das wichtigste ist eig. der Schluss bzw. die IF-Anweisung. Sie funktioniert nicht richtig (oder was ich eher vermute, ich hab nen kleinen Fehler!). Sieht jemand den Fehler?

    Das Programm soll die Strings aus den Textfeldern in den Labels neu sortieren. Er gibt mir immer nur 7 Strings in den Labels aus, obwohl es 8 sein müssten. Es fehlt jedesmal eine andere Zahl bzw. Label.

    Prüfen, ob er Wert null ist... zu einfach?

    Hast du mal ein Debugging gemacht?
    Wieso fangen die Indizes mit 1 (statt mit 0) an?
