I seem to be getting the constructor Employee in class Employee cannot be applied to given types; error and I'm not sure how to fix it. Im fairly new to coding so the simpler explanation the better. method where the error occurs specifically the "new Employee();" in the first line

Collections.sort(employees, new Employee());
System.out.println("\nFirst and Last Names of Employees sorted based on first Name\n");
for (Employee employee : employees) {
System.out.println("First Name: " + employee.getfirstName() + " Last Name: " + employee.getlastName()
+ " Salary: " + employee.getSalary());
}
List<Employee> newHirees = readFile(hirefile);
// Add new Hired employees
employees.addAll(newHirees);
Collections.sort(employees, new Employee());
System.out.println("\nFirst and Last Names of Employees sorted based on first Name after adding new hires\n");
for (Employee employee : employees) {
System.out.println("First Name: " + employee.getFirstName() + " Last Name: " + employee.getLastName()
+ " Salary: " + employee.getSalaryPaid());
}
List<Employee> firedEmployees = readFile(firefile);


System.out.println("\nFirst and Last Names of Employees After removing fired employees\n");
for (Employee fired : firedEmployees) {
String firstName=fired.getFirstName();
String lastname=fired.getLastName();
for (Employee employee : employees) {
if (employee.getFirstName().trim().equals(firstName)
&& employee.getLastName().equals(lastname)) {
employees.remove(employee);
}
}
}
for (Employee employee : employees) {
System.out.println("First Name: " + employee.getFirstName() + " Last Name: " + employee.getLastName());
}
}
