JAVA Implement BagInterface

Implement the BagInterface using the DynamicArray<Item> generic.

Create a NetBeans project
 
Downlad the following Java interface and object classes and import them into your project:
 
 
BagInterface.java

Coin.java
CoinName.java

PiggyBank.java
PiggyBankExample.java
 
You can refer to these “online instructions on importing a Java” source file into a NetBeans project.
Note that you are not allowed to modify any of the downloaded BagInterface and/or object classes in any way!
 
Incorporate the DynamicArray<Item> generic into your project:
 
Download and unzip “NJB_Coll_Lib1.zip”
 
Add the NJB_Coll_Lib1.jar to your NetBeans project:
in the Projects explorer, right-click on Libraries
select the menu item “Add JAR/Folder…”
navigate to and select the NJB_Coll_Lib1.jar file
 
Create a new DynamicBag generic object class that implements the BagInterface (public class DynamicBag<T> implements BagInterface<T>) and uses an instance of DynamicArray<Item> to implement the BagInterface methods.
Remember to import generics.DynamicArray; in this Bag class.

Once you are done, upload the source code file (i.e., DynamicBag.java file).
