Maze program for AP Comp Sci

[bcassillo]

Here is my code.... It is supposed to go throught this maze and can move where there are "." and blocked by "#". I keep getting an out of bounds error. Can anyone help me?

import java.io.*;
public class ProgramMAZE
{ public static char maze[][]=
            {{'#', '#', '#', '#', '#', '#', '#', '#', '#', '#', '#', '#'},
            {'#', '.', '.', '.', '#', '.', '.', '.', '.', '.', '.', '#'},
            {'.', '.', '#', '.', '#', '.', '#', '#', '#', '#', '.', '#'},
            {'#', '#', '#', '.', '#', '.', '.', '.', '.', '#', '.', '#'},
            {'#', '.', '.', '.', '.', '#', '#', '#', '.', '#', '.', '.'},
            {'#', '#', '#', '#', '.', '#', '.', '#', '.', '#', '.', '#'},
            {'#', '.', '.', '#', '.', '#', '.', '#', '.', '#', '.', '#'},
            {'#', '#', '.', '#', '.', '#', '.', '#', '.', '#', '.', '#'},
            {'#', '.', '.', '.', '.', '.', '.', '.', '.', '#', '.', '#'},
            {'#', '#', '#', '#', '#', '#', '.', '#', '#', '#', '.', '#'},
            {'#', '.', '.', '.', '.', '.', '.', '#', '.', '.', '.', '#'},
            {'#', '#', '#', '#', '#', '#', '#', '#', '#', '#', '#', '#'}};

I keep getting an out of bounds error.

Can you post the full text of the error message that shows where the error happens and what the value of the index is?
