Arbeiten an einem Java-Programm, das Gehälter für eine Sammlung von Mitarbeitern verschiedener Typen berechnet, die aus einer TXT-Datei importiert wird.Importieren Sie Daten in Datei und verwenden Sie, um Gehalt zu berechnen
Das Programm baut und erfolgreich läuft, wenn ich auf Kommentar:
System.out.println("\nAverage Salary for 2014: " + (totalSalary/indexYear2014));
System.out.println("\nAverage Salary for 2015: " + (totalSalary/indexYear2015));
aber es scheint nicht, dass die Daten importiert/überhaupt verwendet. Hier
ist der vollständige Code:
package computeemployeesalary;

/**
* This program computes the salaries of a collection of employees of
* different types: Employee, Salesman, Executive
*
* Salary for employee is calculated by multiplying monthly salary by 12
*
* Salary for salesman takes the base of employee, and then adds commission,
* which has a cap of 20000
*
* Salary for executive takes the base of employee, and then adds a bonus
* in the event that the current stock is more than 100

Jede Hilfe wäre sehr geschätzt.
wow, viele Zeilen ... aber Sie sollten uns die Fehlermeldung geben , ein Stack-Trace oder etwas ähnliches, siehe http://stackoverflow.com/help/how-to-ask –
Außerdem haben Sie nicht wirklich eine Frage gestellt. – mwm314
Wie andere Benutzer gesagt haben, sollten Sie klar angeben, was das Programm tun soll und was es stattdessen tut. Außerdem sollten Sie Ihren Code auf einen [SSCCE] (http://www.sscce.org/) reduzieren. Sie werden viel eher auf diese Weise Hilfe bekommen. – elhefe
