Nothing... if you are wondering why you can't create an object from this code it's because you declared it as abstract. Otherwise it seems fine to me...

I think you need to rewrite your toString() method and kvass is right take the abstract off to your class otherwise everything is fine.
if i will rewrite it .. it will be

public class Employee{.....

public String toString(){
return String.format(" %s %s \n social security number: %s ", firstName, lastName, socialSecurityNumber);
}
