The purpose of this repository

This repository contains model, view and controller classes for solving Tower of Hanoi.

Installation in IDEA

2. Right click on class TOHApp.
3. Select Run TOHApp.main()

You are now able to make changes to the project and run it again.

Alternative installation method

1. Clone repository.
2. Run ant default target (builds and runs the application).

Programming your solution

Class TOHApp contains method

static void solve (TowerOfHanoi toh, int numDiscs, Peg from, Peg to)

which you need to modify to solve the problems. The main() of this class calls method solve() with correct parameters for solving the problem, that is, moving all discs from rod A to rod C.

The version of solve() in this repository is a feeble attempt to solve this problem, and you need to replace it with your own version. Still, the feeble version demonstrates the only external methods you need to use:

• class TowerOfHanoi contains method

  move (Peg from, Peg to)
      

  which moves top disc of rod from to rod to. This may throw an exception if the move breaks the rules of Tower of Hanoi, but this exception is caught by the program. Possible exceptions are printed into console.
