Java

Modification 5: Write a method called addEmployeeToDepartment, which doesn’t return a value and has 2 parameters, the first is of type int, and the second of type Employee. This method iterates through all the elements in the listOfDepartments instance variable looking for a Department whose departmentID is equal to the int value passed as the first argument. If it finds it, it adds to it a copy of the Employee object passed as the second argument.

Below is the method header:

/**

* The addEmployeeToDepartment method iterates through the

* listOfDepartments ArrayList looking for a Department whose departmentID

* is equal to the int value passed as the first argument.

* If it finds it, it adds the Employee object passed as the second

* argument.

* @param deptID the departmentID to search for in the list.

* @param empObject the Employee object to be added to the department.

*/   

public void addEmployeeToDepartment (int deptID, Employee empObject)

{

    //provide implementation

}

public class Company
{

private String companyName;
private ArrayList<Department> listOfDepartments;

public Company(String companyName, ArrayList<Department> listOfDepartments)
{
this.companyName = companyName;

ArrayList<Department> dep = new ArrayList<>();

for (Department d : listOfDepartments)
{
dep.add(new Department(d));
}

}

public void addDepartment(Department dept)
{
listOfDepartments.add(new Department(dept));
}

  

public void setDepartmentManager(int deptID, Manager manObject)
{
for (int i = 0; i < listOfDepartments.size(); i++)
{
Department d = listOfDepartments.get(i);

if (d.getDepartmentID() == deptID)
{
d.setDepartmentManager(new Manager (manObject));
  
}
}
}

public String getCompanyName()
{
return companyName;
}

}

this.listOfDepartments = dep;
}

@Override
public String toString()
{

String output = "Company Name: " + companyName + " ";

if (listOfDepartments == null || listOfDepartments.isEmpty())
{
output += "no Departments.";
} else
{
for (Department checkElement : listOfDepartments)
{
output += checkElement.toString();

return output + " ";

}
