Java -

I have two arrays. one is for display, M for mouse moves from top right to somewhere in the matrix. The other matrix called realMaze is where I want to use a random number and move the mouse to another square depending the random number. Im stuck, this is my second question, I tried a switch but that was too complicated. It is not a GUI base program. Basically. here's the question:

Create a path for a mouse to travel in a maze. Use a 2 dimensional array and start the mouse in location array[0][0]. The mouse must find its way to the opposite corner. Repeatedly get a random number representing one of 8 possible moves. A legal move is one that moves forward, does not run off the edge of the maze and does not land on a previous move. If the move is illegal the poor mouse must starts over with location [0][0]. Going forward is defined as the sum of the two array indexes either increasing or staying the same.

Here is my code so far:

import java.util.Scanner;

public class MouseMaze

{

public static void main (String[] args){

Scanner keyboard = new Scanner(System.in);

System.out.println("*** Mouse Maze ***");

int x=0,y=0;

//char [][] maze = new char [10][10];

char cat='C';

char mouse='M';

System.out.println("Enter array dimensions (note: it will be a square so if you enter 5, the maze is 5x5)");

int dim=keyboard.nextInt();

System.out.println("The array will be "+dim+"x"+dim);

char [][] maze = new char [dim][dim];

int [][] realMaze= new int [dim+1][dim+1];

// System.out.println("Array is 10x10");

// if (dim>100)

// System.out.println("You must be crazy, im not making a mouse run that far.");

//initilaze realMaze

int test=0;

//end of initilaze realMaze

do{

int randomNumber=(int)(Math.random()*4-2);

System.out.println("Random Number is: "+randomNumber);

test++;

} while (test<4);

// initialize array

//int dim=10;

for (int row=0; row

for (int column=0; column

maze[row][column]='-';

// end of initialize array

maze[0][0]=mouse;

// print out array

for (int r=0;r

{

for (int c=0; c

{

System.out.print(maze[r][c]+" ");

} //end of c loop

System.out.println();

} //end of r loop

//initilaze second array to hold real moves

for (x=0; x

for (y=0; y

realMaze[x][y]=-1;

System.out.println();

for (int r=0;r

{

for (int c=0; c

{

System.out.print(realMaze[r][c]+" ");

} //end of c loop

System.out.println();

}

// end of second array

} // public static void main end

} // public class MouseMaze end
