Help with an Inheritance issue

Well thanks for the help. I fixed the snippet

and then fixed

and

After those changes I have more errors, which are
C:\cis163\Project5_2\src\Project5_2.java:108: cannot resolve symbol
symbol : method setManagerName (java.lang.String)
location: class Employee
anEmployee.setManagerName(managerName);
^
C:\cis163\Project5_2\src\Project5_2.java:130: cannot resolve symbol
symbol : method getManagerName ()
location: class Employee
System.out.println( "Managers name; " + anEmployee.getManagerName() );
^
I already declared the variable in my SalesEmployee class so I dont understand the error

Help with an Inheritance issue

Ok, I'm getting some errors in my SalesEmployee class which extends Employee class. The error has to do with a variable that isnt in the employee class called "managerName". Its in the SalesEmployee class because thats how the teacher wants it. Did I declare it wrong in my SalesEmployee class or what am I doing wrong. Here is my SalesEmployee class and the main class which tests the class.

/**
* Employee.java
* A class which extends Person and adds
* attributes to further define an Employee
*/
public class Employee extends Person {
/**
* We only need to define the attributes
* of Employee here. Since we have

* Person for free!

* The constructors are somewhat different here.
* Whenever we call our Employee constructor,
* we need to also call the superclass constructor
* to create the part of Employee that was defined
* with the Person class.
*/

//This is calling the Person default constructor
super();
}

* For this constructor, we pass in values for the attributes that
* Person defined. We still need to define those.

this.seniority = inSeniority;
