Question

Here is a java program for employees. I keep getting errors (11 to be exact) like this one below:

/Employees.java:11: cannot find symbol
symbol : constructor Salary(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,double)
location: class Salary

I was wondering if anyone can help me fix my errors and if it were possible, to combine some of the classes together. THank you!

Explanation / Answer

I have done changes in constructors of 3 classes- Hourly, Payroll, and Salary.
You were calling the constructor which wasn't even defined. (The number of parameters in the defined constructor of superclass was different than the number of parameters in the call to superclass constructor inside subclass constructor.

Hourly.java:

public class Hourly extends Payroll
{
protected int hoursWorked;

public Hourly(String empName, String empId, String empAddress, String empCity, String empPhoneNo, String empPosition, String empPayroll, String sSN, double rate)
{
super(empName, empId, empAddress, empCity, empPhoneNo, empPosition, empPayroll, sSN, rate);

hoursWorked = 0;
}

public void addHours(int overTime)
{
hoursWorked += overTime;
}

public double pay()
{
double paycheck = wage * hoursWorked;

hoursWorked = 0;

return paycheck;
}

public String toString()
{
String result = super.toString();

result += " Current hours worked this week: " + hoursWorked;

return result;
}
}

Payroll.java:

public class Payroll extends StaffMember
{
protected String name;
protected String idNumber;
protected String address;
protected String city;
protected String phoneNo;
protected String position;
protected String payroll;
protected String socialSecNo;
protected double wage;

// Constructor sets up employee Payroll with the specified infomation
// @Param empName - Employee Name
public Payroll (String empName, String empId, String empAddress, String empCity, String empPhoneNo, String empPosition, String empPayroll, String sSN, double rate)
{
// Call the superclass instructor
// The first line in the constructor of the derived class must be a call to the superclass
super(empName, empId, empAddress, empCity, empPhoneNo, empPosition);
payroll=empPayroll;
socialSecNo = sSN;
wage = rate;
}

// Returns the pay rate for this employee
public double getWage()
{
return wage;
}

// Returns information about an employee as a string
public String toString()
{
String result = super.toString();

result += " SSN: " + socialSecNo;

return result;
}
// Returns the amount this employee should be paid
public double pay()
{
return wage;
}
}

Salary.java:

public class Salary extends Payroll
{
private double bonus;

public Salary(String empName, String empId, String empAddress, String empCity, String empPhoneNo, String empPosition, String empPayroll, String sSN, double rate)
{
super(empName, empId, empAddress, empCity, empPhoneNo, empPosition,empPayroll, sSN, rate);

bonus = 0;
}

public void salesBonus(double salaryBonus)
{
bonus = salaryBonus;
}

public double pay()
{
double paycheck = super.pay() + bonus;

bonus = 0;

return paycheck;
}
}
