The exception message tells you exactly what the problem is: Multiple decimal separators in pattern "#.##0.00"
A decimal separator in this context is a dot, and your formatter pattern contains multiple (more than one, two to be precise) of these.

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: ProductionWorker.setHireDate

[richard.haines.39]

I've been working on this to long and for some reason I can't figure out what to do?

[mvmalderen]

It seems like you haven't defined a setHireDate() method in your ProductionWorker class.

[richard.haines.39]

I've tried but then it says it conflicts with my employee class...?

[Taywin]

How did you implement it? Also in which class did you implement the method in?

[richard.haines.39]

I tried in the productionworker class by putting public setHireDate() method...im getting really frustrated with it.

[mvmalderen]

Please post the modified version of your code.

[richard.haines.39]

    import java.text.DecimalFormat;
    public class ProductionWorker extends Employee
    {
    public static final int DAY_SHIFT = 1;
    public static final int NIGHT_SHIFT = 2;
    private int shift;
    private double payRate;
    public ProductionWorker(String n, String num, String date,
    int sh, double rate)
    {
    super(n, num, date);
    shift = sh;
    payRate = rate;
    }
    public ProductionWorker()
    {
    super();
    shift = DAY_SHIFT;
    payRate = 0.0;
    }
    public setHireDate()
    {
    hireDate = date;
    }
    public void setShift(int s)
    {
    shift = s;
    }
    public void setPayRate(double p)
    {
    payRate = p;
    }
    public int getShift()
    {
    return shift;
    }
    public double getPayRate()
    {
    return payRate;
    }
    public String toString()
    {
    DecimalFormat dollar = new DecimalFormat("#.##0.00");
    String str = super.toString();
    str += "\nShift: ";
    if (shift == DAY_SHIFT)
    str += "Day";
    else if (shift == NIGHT_SHIFT)
    str += "Night";
    else
    str += "INVALID SHIFT NUMBERS";
    return
    str += ("\nHourly Pay Rate: $" +
    dollar.format(payRate));
    }
    }

[mvmalderen]

Define your setHireDate as follows and put it in your Employee class (remove the other one from ProductionWorker, my bad):

public void setHireDate(String date)
{
    hireDate = date;
}

[richard.haines.39]

wow. thank you very much! I was trying to use it in the productionworker...lol

[Demonix]

make this change
before:

      DecimalFormat dollar = new DecimalFormat("#.##0.00");

after:

      DecimalFormat dollar = new DecimalFormat("#.##");
