Can't get file to complile and don't know how to fix it

[jlgraham]

This is the first course I have ever taken in any programming language. This is my last assignment and totally frustrated. My employee class compiled but get 1 error when I tried to compile my EmpMainline class and I don't know how to fix it. It is in line 65 of my code. can't find symbol constructor Employee location class Employee. I would really appreciate any help on getting this to work. It may be my array. Our last class introduced us to arrays and I was a bit confused but thought I figured them out. Here are the 2 classes.

import javax.swing.*;
import java.util.*;
import java.text.*;

public class EmpMainline
{
	public static void main(String args[])
	{
		String 		last, first, mid, payStr, hoursStr, otStr, vacStr;
		String		birthDateStr, hireDateStr;
		String		simpleDateCalculationOutput;
		double		pay, hours, ot;
		int			vac;
		int			numEmp = 0;
		int 		i;
		Employee    emp[]; //sets up my array

		// now set the size of the array
		emp = new Employee[numEmp];

		// walk through the # employees and get the input
		for(i=0; i<numEmp; i++)
		{
			last = JOptionPane.showInputDialog(null,"Enter employee's last name",
												    "Employee Information",
													 JOptionPane.PLAIN_MESSAGE);   // get employee's last name

			first = JOptionPane.showInputDialog(null,"Enter employee's first name",
													 "Employee Information",
											          JOptionPane.PLAIN_MESSAGE);   // get employee's first name

			mid = JOptionPane.showInputDialog(null,"Enter employee's middle name or initial",
												   "Employee Information",
											        JOptionPane.PLAIN_MESSAGE);

			birthDateStr = Employee.getDate("Enter date of birth (YYYY/MM/DD)", 2, "1930/01/01");

			hireDateStr  = Employee.getDate("Enter date of hire (YYYY/MM/DD)", 2, "1930/01/01");

			payStr = JOptionPane.showInputDialog(null,"Enter employee's hourly wage",
												      "Employee Information",
													   JOptionPane.PLAIN_MESSAGE);
			pay = Double.parseDouble(payStr);

			hoursStr = JOptionPane.showInputDialog(null,"Enter employee's regular weekly hours",
													    "Employee Information",
														 JOptionPane.PLAIN_MESSAGE);
			hours = Double.parseDouble(hoursStr);

			otStr = JOptionPane.showInputDialog(null,"Enter employee's weekly overtime hours",
													 "Employee Information",
													  JOptionPane.PLAIN_MESSAGE);
			ot = Double.parseDouble(otStr);

			vacStr = JOptionPane.showInputDialog(null,"Enter employee's vacation weeks",
													  "Employee Information",
													   JOptionPane.PLAIN_MESSAGE);
			vac = Integer.parseInt(vacStr);

			//get the employee's age at hire
			simpleDateCalculationOutput = Employee.simpleDateSubtraction(birthDateStr, hireDateStr);
			Employee.outputMessage("Your age when you were hired is " + simpleDateCalculationOutput);

			emp[i] = new Employee(last, first, mid, birthDateStr, hireDateStr, payStr, hoursStr, otStr, vacStr);

Look at the constructor of your Employee class: it takes Strings, doubles and an
int as its parameters; you are trying to call a constructor with only nine Strings
as its parameters. It doesn't exist and that's what your compiler is whining about.

Hi, I think you ment to put:

emp[i] = new Employee(last, first, mid, birthDateStr, hireDateStr, pay, hours, ot, vac);

instead of:

emp[i] = new Employee(last, first, mid, birthDateStr, hireDateStr, payStr, hoursStr, otStr, vacStr);

this will solve your proble and I tested it, just put any number greater than zero on your employee number like: int numEmp = 4; is doing something now atleast.

kind regards Sam Rabophala

Thanks everyone. I got it all working and ready to hand in including my Sort and Report Classes. I have made a new post. Would appreciate any replies. Thanks
