Inheritance Constructor error

Question

Hi guys, having a spot of bother with a constructor of a sub-class.
What i am doing is making a super class... Person and a subclass... Administrator
When i am coding my constructor for the administrator every inherited field constructs but my local one does not
The error i get is on the constructor parameter, Cannot find symbol : constructor Person. class: Person
I think it may be something to do with java not knowing what constructor to use
Heres my code
Personpublic abstract class Person{
    // TO DO
    // READ THE COMMENTS AND COMPLETE
    //Attributes
   public String name;
   public String address;
   public String sex;
   public int age;
       public Person(String name, String address, String sex, int age) {
        this.name = name;
        this.address = address;
        this.sex = sex;
        this.age = age;
    }Administrator
public class Administrator extends Person {
    // Attributes
    private String type;
    // TO DO
    // READ THE COMMENTS AND COMPLETE
     * Constructor
     * @param name name of the administrator
     * @param address address of the administrator
     * @param gender sex of the administrator
     * @param age age of the administrator
     * @param type member type of the administrator
    public Administrator(String name, String address, String gender,
            int age, String type) {
        this.name=name;
        this.address=address;
        this.sex= gender;
        this.age=age;
        this.type=type;
    }

If you don't explicity invoke a super constructor, the compiler inserts a call to the no-arg c'tor: super(); If your parent class does not have such a c'tor, that's an error. You'll need to add a call to
super(name, age, gender);
// or whatever parameters the parent's c'tor actually takesas the first line of your child class c'tor.
