Write an abstract class called Staff Member that has two protected String fields

Question

Write an abstract class called Staff Member that has two protected String fields called name and phone, and it also has a two argument constructor that sets those two fields. Don't worry about creating getters and setters for those field values, but you must create a to String method that returns a String with the two values. And include an abstract method in this class called pay() that returns a double. After writing that class, write another class called Volunteer, which inherits from the StaffMember class and has no additional fields. The Volunteer class has a two argument constructor that sets the two field values of its parent class, and it has a pay() method that just returns the value of zero, and it has a toString() method that returns the String "Volunteer: " followed by what the toString() method of the parent class returns.

Explanation / Answer

Below is the 2 class files according to the question,

StaffMember.java

public abstract class StaffMember {

   protected String name;
   protected String phone;
  
   public StaffMember(String name, String phone){
       this.name=name;
       this.phone=phone;
   }
  
   public abstract double Pay();
  
   @Override
   public String toString() {
        return String.format("%s %s", name, phone);
   }
}

Volunteer.java

public class Volunteer extends StaffMember {

   public Volunteer(String name,String phone) {
       super(name,phone);
       // TODO Auto-generated constructor stub
   }

   @Override
   public double Pay() {
       // TODO Auto-generated method stub
       return 0;
   }
   public String toString() {
        return String.format("Volunteer :"+"%s %s", super.name, super.phone);
   }

}

!! Have a good Day !!
