How to write code in subclass to resume some of the logic in parent class?

I have product object and two class AsiaProductValidation and ProductValidation.AsiaProductValidation is called when region is Asia. ProductValidation is parent class which has some functions that can be used in AsiaProductValidation. I want to know can i write validate method in AsiaProductValidation to reuse some checks written in parent class

 class Product{
        int id,
        long price;
        String region;

        Product(int id, long price, String region){
            this.id = id;
            this.price = price;
            this.region = region;
       }

       // getters for id,price and locId
    }

    Class ProductValidation{
       public static validate(List<Product> list, int qty, int totalAvailableQty){
         if(list.size() == 0)
            return //some expceptio
         if(qty < totalAvailableQty){
            return //some exception
         }

         if(qty == totalAvailableQty){
             calculate(list);
          }

        }

        private long[] calculate(List<Product> list){
          return list.stream().mapTolong(p -> p.getPrice()).toArrat()l
        }



    }

    class AsiaProductValidation{


    public static validate(List<Product> list, int qty, int totalAvailableQty){
        // First two conditions stay same as above
        if(list.size() == 0)
            return //some expceptio
         if(qty < totalAvailableQty){
            return //some exception
         }
          //only calculate function changes, how can i use inheritance here to avoid writing above two 
         checks in this class. and also call above two checks when this class is called?

         calculate(list);
    }

     private long[] calculate(List<Product> list){
          return list.stream().mapTolong(p -> p.getPrice() < 100 ? 0 : p.getPrice()).toArray();l
        }
    }

    class RegionCalculate{

      public void call(List<Product> list, int qty, int totalAvailableQty ){
         if(region == Asia){
                AsiaProductValidation.validate(qty,totalAvailableQty )
         }
         else{
             ProductValidation.validate(qty,totalAvailableQty)
         }
       }

    }

    long[] price = {40, 90, 40};

    List<Product> list = new ArrayList();
    list.add(new Product(1,100, "ASIA"));
    list.add(new Product(1,110, "AUS));
    list.add(new Product(1,90, "EUROPE"));

    RegionCalculate reg = new RegionCalculate();
    reg.call(list, 1100, 500);
