This code defines a method named spawnNewTetromino, likely a part of a Tetris game, that generates and initializes a new tetromino piece in the game. Here's what each part of the code does:

1. Select a random Tetromino type:

   TetrominoType.values()[random.nextInt(TetrominoType.values().length)];
   

   • TetrominoType.values() retrieves an array of all possible Tetromino types (for example, the Tetris pieces like I, O, T, L, and Z shapes).
   • random.nextInt(TetrominoType.values().length) generates a random index within the bounds of the array.
   • This selects a random Tetromino type from the defined enumeration.

2. Create a new Tetromino object:

   currentTetromino = new Tetromino(type);
   

   • Initializes a new Tetromino object with the randomly selected type.

3. Set the initial rotation:

   currentRotation = 0;
   

   • Sets the piece's rotation to its default (0 degrees or no rotation).

4. Set the initial position:

   currentPosition = new Point(BOARD_WIDTH / 2 - 2, 0);
   

   • Positions the Tetromino near the top center of the game board horizontally.
   • The horizontal position (BOARD_WIDTH / 2 - 2) centers the piece on the board width.
   • The vertical position (0) places the piece at the top of the board.

5. Check if the new piece can be placed:

   if (!canPlaceTetromino(currentPosition.x, currentPosition.y, currentRotation)) {
       System.out.println("Game Over");
   }
   

   • It calls the canPlaceTetromino method to see if the Tetromino can be placed at the calculated position (top-center) without overlapping existing blocks or exceeding the game board boundaries.
   • If placement is not possible (returns false), it prints "Game Over", which likely means the game ends as the pieces have stacked too high or something is blocking the top of the board.

Summary:

The method spawns a new Tetromino at the top center of the board, initializes its type, rotation, and position, then checks if it can be placed. If it cannot be placed, the method indicates that the game is over.
