Given that HourlyEmployee and SalariedEmployee are subclasses of FullTimeEmployee, suppose we have:

FullTimeEmployee full = new FullTimeEmployee();

HourlyEmployee hourly = new HourlyEmployee();

SalariedEmployee salaried= new SalariedEmployee();

Which one of the following assignments would be legal at (i) compile-time and/or (ii) run time or have no errors?

1. salaried = (SalariedEmployee) full;
2. salaried = full;
3. salaried = (FullTimeEmployee) full;
4. hourly = (HourlyEmployee) full;
