Thank guys, I managed fixing the first problem, am facing a second problem now, this This is what i get after compiling Database.java file

(Toggle Plain Text)

Note: Database.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for deta

So this is what i did

(Toggle Plain Text)

moderator@amer:~/Desktop/amer$ javac -Xlint:unchecked Database.java
Database.java:14: warning: [unchecked] unchecked call to addElement(E) as a member of the raw type java.util.Vector
                EmployeesData.addElement(emp);
                                        ^
1 warning
moderator@amer:~/Desktop/amer$

This is my Database.java file code

(Toggle Plain Text)

import java.util.*;
import java.io.*;
import java.lang.*;
import java.util.Vector;

public class Database 
{
	Vector EmployeesData = new Vector();
		
	public void addEmployeeData(Employee emp)
	{
(This is line 14)==>>		EmployeesData.addElement(emp);
	}
	
	public void printEmployeesData (PrintStream ps)
	{

		Employee tempEmp;
		int k=0;
		
	ps.println(new String("Amer Al-Tagi" ));
    	ps.println(new String("Homework 3: Payroll Calculations:"));
    	ps.println(new String(""));
    	ps.println(new String("Full Time Employees"));
    	ps.println(new String("================================================================="));
	ps.println(new String("ID" + "		" + "FName" + "	" +"LName"+"	"+"Dept"+"	"+"Salary"));
	ps.println(new String("================================================================="));
    	
		for (k=0; k<EmployeesData.size(); k++)
		{			
			if (EmployeesData.elementAt(k) instanceof FullTimeEmployee)
			{
				tempEmp = (Employee) EmployeesData.elementAt(k);
				tempEmp.printEmployee(ps);
			}
			
		}
		
		ps.println(new String(""));
		ps.println(new String("Part Time Employees"));
    		ps.println(new String("================================================================="));
		ps.println(new String("ID" + "		" + "FName" + "	" +"LName"+"	"+"Dept"+"	"+"Salary"));
		ps.println(new String("================================================================="));
    	
		for (k=0; k<EmployeesData.size(); k++)
		{			
			if (EmployeesData.elementAt(k) instanceof PartTimeEmployee)
			{
				tempEmp = (Employee) EmployeesData.elementAt(k);
				tempEmp.printEmployee(ps);
			}
			
		}
	}
	

}

Try replacing line 12 (which you have marked line 14) with this:

(Toggle Plain Text)

Vector<Employee> EmployeesData = new Vector<Employee>();

Also, you still have too many import statements. java.lang.* is imported automatically in any java project, and java.util.* includes java.util.Vector. So the only import statements you need are:

import java.util.*;
import java.io.*;
