Im currently working on a tetris program I wanted to know if someone could correct the implementation of my saveToFile and retrieveFromFile methods. The saveToFile method should allow the user to save a run of the game to a file that they are allowed to name with $.$gam appended to it$.$ The retrieveFromFile should allow the user to access and display a previously played game. I wont be showing my full game just what I believe may be neccessary for the fix.

Program:

public class TetrisGame

$\{$

private TetrisBrick fallingBrick;

private int rows $=2$;

private int cols $=2$;

private int numBrickTypes $=7$;

private Random randomGen;

private int$[][]$ background;

private int state;

private int score;

public TetrisGame$($int rows, int cols$)$

$\{$

this.rows $=$ rows;

this.cols $=$ cols;

initBoard$()$;

this.randomGen $=$ new Random$()$;

spawnBrick$()$;

$\}$

public String toString$()$

$\{$

String gameFile$=""$;

for$($int row$=0$; row
