[SOLVED] javaMulti-Level Undo Redo

Lab 3 (Multi-Level Undo Redo)

Learning Objectives

The purpose of this lab is to give you an opportunity to learn the following skills:

• Refactoring existing code if necessary.
• Learning how to implement multi-level undo redo.
• Applying object-oriented design principles to develop an elegant solution.

Implementing Multi-Level Undo and Redo in the FreeCell Game

For this lab, please do the following activities:

1. If necessary, refactor/redesign your initial solution based on the design principles youve seen in the lectures and labs.
2. Make a plan how you are going to implement undo and redo. Discuss your plan with the lab instructor and make sure that you understand the requirements of the multi-level undo redo features. Being able to design an elegant solution is one of this labs main objectives, so please put significant effort to come up with a good design.
3. Add the multi-level undo and redo features to your FreeCell implementation. Please ask questions if you need clarification.

Evaluation Criteria

This lab has a total of 100 marks and is worth 6% of your final grade. The marks will be allocated as follows:

• 70%: the correctness of your solution.
• 20%: the overall quality of your solution.
• 10%: documentation using Javadoc
