Question

abstract class Product {
    protected float price;

    // return the price of a particular product
    abstract float price();
}

Part 1: (6096) 1. Carefully study the class structure in Products.java. 2. Design a generic container called GenericOrder that acts as a collection of an arbitrary number of objects in Products.java. Design a mechanism that 3. Design and implement a subclass of GenericOrder called ComputerOrder that takes an arbitrary number of different classes of ComputerPart objects, 4. Design and implement a subclass of GenericOrder called PartyTrayOrder that takes an arbitrary number of different classes of Cheese objects, Fruit 5. Design and implement a class called OrderProcessor. You must implement at least the following methods: gives each instance of the container a unique identifier. Implement as many methods as necessary. You must use Java generics features. Peripheral objects, and Service objects. Implement as many methods as necessary objects, and Service objects. Implement as many methods as necessary. accept; Wthis method accepts a GenericOrder or any of its subclass objects and stores it in any internal collection of OrderProcessor process, this method sorts all accepted orders in the internal collection of GenericÖrder into collections of ComputerPart, Peripheral, Cheese, Fruit, and Service. You must associate each object with the unique identifier. You may refer to the TwoTuple.java example in the text book dispatchXXx this method simulates the dispatch of the sorted collections. For example, the method dispatchComputerParts) should produce this output Motherboard name-Asus, price-$37.5, order number-123456 Motherboard name-Asus, price-$37.5, order number-987654 RAM name-Kingston, size-512, price-$25.0, order number-123456 You may overload each of the above methods as you think necessary. 6. Create a client class to test OrderProcessor. You will need to create a datagenerator for testing purpose. It is not mandatory but you may use a variation of Data Generator in TIj pages 637 to 638. 7. Pack the above codes into one single zip file and send it to your tutor Part 2: (3596) 8. Design and implement a subclass of GenericOrder called ComputerPartyOrder that takes an arbitrary number of different classes of ComputerPart objects, Peripheral objects, Cheese objects, Fruit objects and Service objects 9. Create another client class that creates ComputerPartyOrder. Modify OrderProcessor if necessary 10. Pack the above codes into a second zip file and send it to your tutor

Explanation / Answer

The answer for your Part2 is given below :  

public class GenericOrder<T> {

private static long counter = 1;

private final long orderNumber = counter++;

private List<T> orderItems;

public GenericOrder(){

orderItems = new ArrayList<T>();

}

public long getOrderNumber() {

return orderNumber;

}

public void addItem(T newItem) {

orderItems.add(newItem);

}

public List<T> getItems(){

return orderItems;

}

public void setItems(List<T> orderItems){

this.orderItems = orderItems;

}

}

for Part 3 :  three overloaded methods with <T extends ComputerPart>, <T extends Peripheral>, and <T extends Service>

similarly you can carry on which below parts :)
