Assume that class Item has following two private data fields:

      private String name; private int code;

      and following constructor:

      public Item(String n, int c) { name = n; code = c; }

     Now, we want to write a class called ElectronicItem that inherits the

     properties of class Item as follows having only one data field:

     public class ElectronicItem extends Item {

            private double price;

 

    The constructor of class ElectronicItem can be written as follows:

 

  1. public ElectronicItem(String n, int c, double p)

    { this(n, c); price = p; }

     

  2. public ElectronicItem (String n, int c, double p)

    { Item.super(n, c); price = p; }

     

  3. public ElectronicItem (String n, int c, double p)

    { Item.name = n; Item.code = c; price = p; }

     

  4. public ElectronicItem(String n, int c, double p)

    { super(n, c); price = p; }
