Need help with Maze project.

[Mumby]

I've been searching the internet for a few days now looking for an answer to my problem but I honestly couldn't find anything similar to my program mainly due to the fact we are using the TextIO class to read the text file.
The task is

"You are required to write a program that will load a simple maze from a text file, display this on the
screen and allow the user to guide an on-screen marker to the maze exit. The maze is defined as a
grid of characters in the file with the following
character definitions:
‘0’ = maze wall
‘1‘ = maze floor
‘2’ = maze entrance
‘3’ = maze exit

E.g. This is a 39*25 maze.

And I've managed to draw the maze up but the thing I am stumped with is this. :S

"Place a game character at the entrance of the maze (this character could be represented by a
number or letter (e.g. ‘9’ or ‘A’) or some other character of your choice)."

This is my code so far:

public class Main {



public static void main(String[] args) {
TextIO.readFile("sample_maze.txt");
// sample_maze2.txt has a line with two numbers on it saying how many rows and
// how many columns of characters there are in the rest of the file.
// All calls to TextIO.get methods read now read from sample_maze2.txt.

int rows = TextIO.getInt(); // this is the number of rows in the file (maze)
int cols = TextIO.getlnInt(); // this is the number of columns in the file (maze)
char[][] array = new char[rows][cols];
// Each line of sample_maze.txt contains cols number of characters
// and there are rows number of lines
for (int i=0; i < rows; i++) {
for (int j=0; j < cols; j++) {
array[i][j] = TextIO.getChar();
}
TextIO.getln();
}
TextIO.readStandardInput(); // This closes the file
TextIO.putln("Display the maze using 'maze' characters:");
// In the maze project, whenever you read a '0' you display a wall character
// whenever you read a '1' you display a path character
// whenever you read a '2' you display an entrance character
// whenever you read a '3' you display an exit character
for (int i=0; i < rows; i++) {
for (int j=0; j < cols; j++) {
if (array[i][j]=='0') TextIO.put('\u2588');
if (array[i][j]=='1') TextIO.put('\u4500');
if (array[i][j]=='2') TextIO.put('S');
if (array[i][j]=='3') TextIO.put("F");
}
TextIO.putln();
}


}
}

Any ideas? :S

So basically your character can never move to a square with a '0' in it (It's a wall); it starts at the position with a '2' in it and ends at the position with a '3' in it. The character can move up, down, left or right. Is this a start for you if you use a simple two dimensional array of chars?

kind regards,
