numberformatexception Fehler bei der Ausgabe

Question

Ich bekomme den folgenden Fehler beim Kompilieren und Ausführen meines Programms. Was habe ich bei der Formatierung vermisst?

meine CSV-Datei sieht wie folgt aus:

David, Curtis, 138, W Plumtree Ln, 8012985656 Paul, Taylor, 99, Wikapee St, 8015984578

Exception in thread "main" java.lang.NumberFormatException: For input string: "8012985656"

Answer 1

Integer maximale Größe ist 2,147,483,647, Sie versuchen, 8,012,985,656 zu analysieren.

Verwenden Sie stattdessen Long und Long.valueOf().
