Help for a java Newbie please!

Question

Hey guys I'm writing this program for my Java 1 class I can't seem to get it complie. This is the first time we've worked with building out own classes. And I have a feeling that I'm doing something small and silly. If someone could just take a look at it I'd be more than happy.
This is the Class we had to write it has 4 different fields of "employee information" This one looks fine.
public class Employee
   private String name;           
   private int idNumber;      
   private String department;
   private String position;
   public Employee(String theName, int theIdNumber, String theDepartment,
                    String thePosition)
         name = theName;
         idNumber = theIdNumber;
         department = theDepartment;
         position = thePosition;
   public void setName( String theName )
         name = theName;
   public void setIdNumber( int theIdNumber )
            idNumber = theIdNumber;
   public void setDepartment( String theDepartment )
            department = theDepartment;
   public void setPosition( String thePosition )
            position = thePosition;
   public String getName()
            return name;
  public int getIdNumber()
            return idNumber;
  public String getDepartment()
              return department;
  public String getPosition()
             return position;
} I think this one is good, it compiles just fine.
Now we had to write a program that accesses the class and store "employee information" for 3 different employees and recall it. It only recalls for one right now, it doesn't compile though... sad day. Any help would be AMAZING THANKS in advanced.
import javax.swing.JOptionPane;
public class EmployeeInfo
   public static void main(String[] args)
       String firstEmployeeName = "Susan Meyers";
       String secondEmployeeName = "Mark Jones" ;
       String thridEmployeeName = "Joy Rogers";
       int firstEmployeeId = 47899;
       int secondEmployeeId = 39119;
       int thirdEmployeeId = 81774;
       String firstEmployeeDepartment = "Accounting";
       String secondEmployeeDepartment = "IT";
       String thirdEmployeeDepartment = "Manufacturing";
       String firstEmployeePosition = "Vice President";
       String secondEmployeePosition = "Programmer";
       String thirdEmployeePosition = "Engineer";
       Employee Employee1 = new Employee();
       Employee1.setName(firstEmployeeName);
       Employee1.setIdNumber(firstEmployeeId);
       Employee1.setDepartment(firstEmployeeDepartment);
       Employee1.setPosition(firstEmployeePosition);
       Employee Employee2 = new Employee();
       Employee2.setName(secondEmployeeName);
       Employee2.setIdNumber(secondEmployeeId);
       Employee2.setDepartment(secondEmployeeDepartment);
       Employee2.setPosition(secondEmployeePosition);
       Employee Employee3 = new Employee();
       Employee3.setName(thirdEmployeeName);
       Employee3.setIdNumber(thirdEmployeeId);
       Employee3.setDepartment(thirdEmployeeDepartment);
       Employee3.setPosition(thirdEmployeePosition);
       JOptionPane.showMessageDialog(null, "Name          ID Number   " +
                                     "Department      Position     /n" +
                                     Employee1.getName() + "   " +
                                     Employee1.getIdNumber() + "   " +
                                     Employee1.getDepartment() + "      /n");
  System.exit(0);
}

Also the compiling error I get is

       Employee Employee1 = new Employee();
