                while (model.moveTetromino(0, 1)) {
                }
                model.fixTetromino();
                break;
            case KeyEvent.VK_P:

                if (timer.isRunning()) {
                    stopGame();
                } else {
                    startGame();
                }
                break;

This code handles keyboard inputs for a game, likely a Tetris-like game, responding to specific key presses to control the player's actions. Here's what each part of the code does:

KeyEvent.VK_LEFT: When the Left Arrow key is pressed, the moveTetromino(-1, 0) method is called, moving the current tetromino (playing piece) one step to the left on the game grid.
KeyEvent.VK_RIGHT: When the Right Arrow key is pressed, the moveTetromino(1, 0) method moves the current tetromino one step to the right on the game grid.
KeyEvent.VK_DOWN: When the Down Arrow key is pressed, the moveTetromino(0, 1) method moves the tetromino one step downward (lower on the grid).
KeyEvent.VK_UP: When the Up Arrow key is pressed, the rotateTetromino() method rotates the tetromino, likely to its next orientation (e.g., for L-shaped pieces, shifting between 4 possible rotations).
KeyEvent.VK_SPACE: When the Spacebar key is pressed, the current tetromino "hard drops" to the bottom of the grid:
- A while loop repeatedly calls moveTetromino(0, 1) to move the tetromino downward as far as possible, stopping when it can no longer move.
- After the hard drop, the fixTetromino() method is called, likely to lock the tetromino into place on the game grid.
KeyEvent.VK_P: When the 'P' key is pressed, it toggles the pause functionality for the game:
- If the timer (which probably controls the game's update loop) is running, stopGame() is called to pause the game.
- Otherwise, startGame() resumes the game.

In summary, this code implements movement, rotation, hard drop, and pause functionality for a Tetris-like game using specific keyboard inputs.
