THE EMPLOYEE CLASS

/**
* This is the class Employee.
* @author (***************************)
* @version (1.0)
*/
public class Employee extends Person
/**
* Instance variables of Employee, the attributes of the class.
*/
{
private Date dateStarted;
private float salary;
private int id;

/**
* Constructors for objects of class Employee
*/
public Employee(String nme, char sex, Date dob, int number, Date start)
{
super(nme,sex,dob);
id = number;
dateStarted = new Date(start);
salary = 0.0f;
}

/**
* Methods of the class Employee
*/

public boolean equals (Employee other)
{
return super.equals(other) && id == other.id && salary == other.salary &&
dateStarted.equals(other.dateStarted);
}

public void setSalary(float salary);
{
??? //NEED NEW CODE HERE ALSO FOR THIS PART TO WORK NOT SURE WHAT TO DO
}

public Employee (Employee other)
{
this(other.salary,other.id,other.dateStarted);
}

THE BIT IN ORANGE NEEDS TO BE CHANGED TO WORK ( Cannot find symbol - Constructor Employeee (float, int, Date)

public void copy (Employee other)
{
dateStarted.copy(other.dateStarted); // QUESTION 4 Not changed Dont know what to do
salary = other.salary;
id = other.id;
}

public String toString()
{
return "Employee Number: "+ id + "salary " + salary + "Started: " + dateStarted.toString();
}

public Date getDateStarted()
{
return dateStarted;
}
}

[Fubarable]

for this code here:

public Employee (Employee other)
{
  this(other.salary,other.id,other.dateStarted);
}

The this(...) call here is nothing more than a call to your other Employee constructor, and it has to match that constructor exactly. Thus if the first parameter in the other constructor is a String, the first parameter in your this(...) call must be a String too.

So take a very close look at your Employee constructor, especially all the parameters used and the variable types for the parameters, and use these same paramters when calling this(...).

for the second problem, understand that a "setter" method, a method that has setXXX in it, is used to update a class's instance fields with the parameter passed. For example if I have a class like so:

class Fubar()
{
  int myValue;
}

and I wanted to change myValue, I'd do something like this:

public void setMyValue(int myValue)
{
  this.myValue = myValue;
}

Notice that I use "this" on the left side to tell the compiler that I want the class's instance myValue on the left of the assignment, the one held by the class (by "this") and the parameter myValue on the right of the assignment.
