Ich versuche, halte ich den Fehler jedoch innerhalb der EmployeesApplet Klassendaten aus der Salaried Klasse zuzugreifentoString Unter Verwendung von Informationen zu drucken
auf immerEmployeesApplet.java:292: Fehler: inkompatible Typen: String nicht konvertiert werden können to int Angestellte S = neue Angestellte (tf [0] .getText(), tf [1] .getText(), tf [2] .getText(), tf [3] .getText());
hier ist die Salaried Klasse
public class Salaried extends Employee
{
private double weekly_salary;
public Salaried(String first_name, String last_name,int e, double w) // one constructor
{
super(first_name,last_name, e);
weekly_salary = w;
}
public String toString()
{
return "Salaried Employee: " +super.toString() + " \nWeekly Salary: $" + weekly_salary ;
} // toString method
}
