This code sets up a foundational structure for a Tetris-style board game. Here's what each part does:

1. public static final int BOARD_WIDTH = 10;
   This defines a constant BOARD_WIDTH with a value of 10, representing the width of the game board (number of blocks or units horizontally).

2. public static final int BOARD_HEIGHT = 20;
   This defines a constant BOARD_HEIGHT with a value of 20, representing the height of the game board (number of blocks or units vertically).

3. private int[][] board;
   Declares a private 2D array board, likely representing the game grid. Each cell in the array might store information about whether a specific square is empty or filled (e.g., 0 for empty, 1 or other values for filled or color-coded squares).

4. private Tetromino currentTetromino;
   Defines a private reference currentTetromino which likely represents the current falling Tetromino piece (a shape made up of 4 squares, such as T, I, O, L, etc.). The class Tetromino is likely custom-defined to manage properties of these shapes.

5. private Point currentPosition;
   Declares a private Point object currentPosition to represent the position of the current Tetromino on the game board. This could hold the x and y coordinates (row and column) where the top-left corner (or reference point) of the Tetromino is located.

6. private int currentRotation;
   Declares a private integer currentRotation to represent the rotation state of the current Tetromino. It might track which rotation position (e.g., 0°, 90°, 180°, or 270°) the Tetromino is in.

7. private Random random;
   Declares a private Random object random, which is likely used to generate random numbers. In the context of Tetris, it might be used to randomly select the next Tetromino shape to spawn on the board.

Summary

This code defines constants for a game board's dimensions and several private variables for managing aspects of a Tetris-like game: the game board, the active Tetromino, its position and rotation, and a random number generator for Tetromino selection.
