Access a private variable from the superclass (JAVA)

Question

Ok so I have studied java all semester and thought I had a clear understanding about inheritance and super/sub classes. Today we were given as assignment for making a superclass

Answer 1

package com.action.product;

public class ProductAction{
  public static String strCategoryName;

  public String getStrCategoryName() {
    return strCategoryName;
  }
  public void setStrCategoryName(String strCategoryName) {
    this.strCategoryName = strCategoryName;
  }

}

-----------------------------------------------------------------------

package com.DAO.product;

public class ProductDAO extends ProductAction {

   @SuppressWarnings("static-access")
   public String addnewProductValidation(){
       System.out.println("======through_name======="+super.strCategoryName);

       System.out.println("======through_getters======="+super.getStrCategoryName());

   }
}

Can initialize variables as static. No need to create object
