Invoking Superclass Methods

• Can't access private fields of superclass
  public class Manager extends Employee
  {
     public double getSalary()
     {
        return salary + bonus;  // ERROR--private field
     }
     ...
  }
• Be careful when calling superclass method
     public double getSalary()
     {
        return getSalary() + bonus;  // ERROR--recursive call
     }
