How can I implement a maze solver in Java?

You can implement a maze solver in Java using algorithms like Depth-First Search (DFS) or Breadth-First Search (BFS). Would you like a code example?

Yes, please provide a code example using DFS.

Here's a simple DFS implementation:

public class MazeSolver {
    public static boolean solveMaze(int[][] maze, int x, int y) {
        // Check if (x, y) is a valid position
        if (x < 0 || y < 0 || x >= maze.length || y >= maze[0].length || maze[x][y] == 1) {
            return false;
        }
        // Check if we've reached the destination
        if (maze[x][y] == 9) {
            return true;
        }
        // Mark the cell as visited
        maze[x][y] = 1;
        // Explore neighbors
        if (solveMaze(maze, x + 1, y) || solveMaze(maze, x, y + 1) || 
            solveMaze(maze, x - 1, y) || solveMaze(maze, x, y - 1)) {
            return true;
        }
        // Unmark the cell (backtrack)
        maze[x][y] = 0;
        return false;
    }
}

This code checks for valid moves and backtracks if necessary.

What does the '9' represent in the maze?

In the maze, '9' typically represents the destination or exit point. The solver will try to reach this point from the starting position.
