Java Iterator Program

I need this to be done in Netbeans and I also need the entire program file named "week 3 animal Iterator" posted.

Write a Java program (non-GUI preferred) to demonstrate the use of Iterator.

The program should allow a user to do the following:

• Allow the reading of a collection of animal objects from an external file.
• Output on screen the content of a collection of animal objects.
• Use Iterator to achieve these goals.

Include a brief documentation (in the code or in a separate document) to explain the input (if any), processing and output of the program.
