Java-Appi

Okay Leute,

ich Poste gerade mal 2 Sachen hier in das Forum und schon glaubt Ihr mich zu kennen... LOL... sag ich nur.

Okay ich gebs zu, ICH bin nicht der Beste Programmierer. Ich bin gerade in einer Online-Universität in dem Java-Kurs für Anfänger. Dort ist nunmal alles auf Amerikanisch. Und da ich ein Amerikaner bin hab ich auch keine Probleme die Texte (Aufgabenstellungen) zu verstehen. Diese Codes wurden von mir persönlich erstellt und nicht von irgendwo "zusammengeklaut"... Aber Denkt doch bitte was Ihr wollt.

Ein wenig hilfe hätte ich schon erwartet von so "erfahrenen" Programmierern wie "euch".

Hier ist ein Update von meinem Programm. Dort habe ich nun noch einen Fehler. Zwar dass ich eine Endlosschleife erstellt habe und ich nicht weiss wie ich diese anhalten kann. Vielleicht kann mir Bitte ein Hilfsbereiter Programmierer weiterhelfen.

vielen Dank im vorraus

Hallo liebe Leute,

ich habe ein kleines Java-Programmierungsproblem. In dem unten stehendem Quellcode müsste die monatliche zahlung bei jedem Output stehen. Nun ist meine Frage.

Wie kann ich die monatliche Zahlung in jedem der 3 Ausgaben einfügen?

Vielen Dank für schnelle Antworten
