Modifythe above code like this:
Supplement the checkYourMove() method by including the remaining if statements that allow the maze participant to escape the maze.
1. if(currentCell == 5 && advance == true)
{
. . .
}
if(currentCell == 6 && advance == true)
{
. . .
}
if(currentCell == 9 && advance == true)
{
. . .
}
2. utilize the score variable to assign a score to each move. Also for extra credit you can track the number of moves that the user makes in their escape of the maze.
Solution
Please follow the code and comments for description :

OUTPUT :
***************************
----The Maze Strategy---
You have entered the maze!!
There is no turning back!!
current position: cell 1
make your move (W, A, S, D)
(W = up, A = left, S = down, D = right)
D
you moved to the right
continue through the maze
current position: cell 2
move again(Y or N)?
Y
make your move (W, A, S, D)
(W = up, A = left, S = down, D = right)
S
you moved down (downward)
continue through the maze
current position: cell 5
move again(Y or N)?
Y
make your move (W, A, S, D)
(W = up, A = left, S = down, D = right)
D
you moved to the right
continue through the maze
current position: cell 6
move again(Y or N)?
Y
make your move (W, A, S, D)
(W = up, A = left, S = down, D = right)
D
you moved to the right
continue through the maze
current position: cell 9
move again(Y or N)?
Y
make your move (W, A, S, D)
(W = up, A = left, S = down, D = right)
D
you moved to the right
Escaped Through the Maze.!
current position: cell 9
move again(Y or N)?
N
***************************
Total Moves Done : 5
Hope this is helpful.
