I need help with this problem

[TeeTea02]

Create a class called Employee. An Employee should have four pieces of information as instance variables – first name (type String), last name (type String), monthly salary (type double), and dependents(type int). Your class should have a constructor that initializes the four instance variables. Provide a get and set method for each instance variable. In addition, provide a method named getAnnualSalary that determines the annual salary of the employee (i.e. monthly salary multiplied by 12), and returns the annual salary (a double value). Write a test application named EmployeeTest that demonstrates class Employee's capabilities.

This what I have so far but I and I can't get the test to work because of some problem with the constructor.

package employee;
 
public class Employee {
 
    private String firstName;
    private String lastName;
    private double _monthlySalary; // monthly salary
    public int dependents;
 
    //constructor
   public Employee(String first, String last, double salary, int dep)
   {
      firstName= first;
      lastName= last;
      _monthlySalary= salary;
      dependents= dep;
     }
 
   // end Employee constructor
   public String getFirstName()
   {
       return firstName;
   }
 
   public void setFirstName(String first)
    {
        firstName= first;
}
   public String getLastName()
   {
       return lastName;
   }
    public void setLastName(String last)
    {
        lastName= last;
}
    public int getDependents()
    {
        return dependents;
}
    public void setDependents (int dep)
    {
        dependents= dep;
    }
 
public void setMonthlySalary ( double salary)
{
    _monthlySalary= salary;
 }
public double getMonthlySalary ()
{
    return _monthlySalary;
}
public double getAnnualSalary()
{
    return getMonthlySalary() *12;
}
}

here is the test

package employee;
 
import java.util.Scanner;
 
 
public class EmployeeTest
{
    public static void main( String args[] )
    {
        Employee e1 = new Employee ();
 
        Scanner input = new Scanner( System.in );
        String first;
        String last;
        double salary;
 
        System.out.print( "Enter the first name of the first employee: " );
        first = input.next();
        employee1.setFirstName( first );
 
        System.out.print( "Enter the last name of the first employee: " );
        last = input.next();
        employee1.setLastName( last );
 
        System.out.print( "Enter the first employee's monthly salary: " );
        salary = input.nextDouble();
        employee1.setMonthlySalary( salary );
 
        System.out.print( "Enter the first name of the second employee: " );
        first = input.next();
        employee2.setFirstName( first );
 
        System.out.print( "Enter the last name of the second employee: " );
        last = input.next();
        employee2.setLastName( last );
 
        System.out.print( "Enter the second employee's monthly salary: " );
        salary = input.nextDouble();
        employee2.setMonthlySalary( salary );
 
 
        System.out.printf( "Now displaying employees' full names and annual salary.\n");
        System.out.printf( employee1.getFirstName()," ", employee1.getLastName(), "     ", employee1.getAnnualSalary(), "\n" );
        System.out.printf( employee2.getFirstName()," ", employee2.getLastName(), "     ", employee2.getAnnualSalary(),  "\n" );
 
 
    }
}
