Java progamming

Question:Using our Stack Data Structure for storing Disk objects (see attached zip file), implement the game The Towers of Hanoi for 3 disks and 3 columns (as simulated at: http://www.mathsisfun.com/games/towerofhanoi.html). Your program should use the Scanner class for asking the user which column they are taking the disk from and which column they are adding the disk to. It should also enforce the rule that a larger disk can not be placed on top of a smaller disk. Your program should detect when the goal is accomplished and display how many moves it took the user to complete.
Given : entire set of codes (Program is already done 70% by the professor). Read the word file and zip folder
Small Questions for the expert after the assignment is completed:
1) Which parts of the assignment were you not able to complete fully? For each, explain why you were unable to complete this part and what steps you took to attempt to complete it. Give me as much detail as possible such that I may award partial credit where it is due
2)what would you do differently if you could do this assignment again?

For the idea check the word file
