Question

I have a 2D array of objects of class Cell. In a separate Maze class I read in the 2D array from a file, and now I need to have a method that returns the entire array as a String. I’m not sure how to go about doing this, any help would be wonderful(I have a method in the Cell class that will return the cell as a string).

Answer 1

Print your matrix with 2 nested loops:

String temp = "";

// foreach row...
for( int i = 0; i < cells.length; i++ )
{

    // ... move across columns
    for( int j = 0; j < cells[i].length; j++ )
    {

        temp += (cells[i][j] + " ");

    }

    // let's move to a new line
    temp += "\n";

}

System.out.println(temp);

Granted that your Cell object has a toString() method.
