a backgammon game

I need a code that uses this methods.

how the code must be written :

import java.util.Arrays; import java.util.Random; import java.util.Scanner;

public class Backgammon { private int[] board; // Positive numbers - white pieces, negative - black pieces. private int[] eaten; // 2 cells - 1st cell for whites eaten pieces, 2nd for blacks. private int[] cubesUsages; // How many more usages do we have for each cube private boolean whitesTurn; // Is it whites turn? private Random rd = new Random(); // Random generator. private Scanner sc = new Scanner(System.in); // For getting the users position and cube to use. Backgammon() { // TODO } Backgammon(int board_size) { // TODO } @SuppressWarnings("unused") public void initBoard() { // useful when playing more than 1 game. initBoard(24); } public void initBoard(int boardSize) { // ... } public String toString() { // Should look like: // [2, 0, 0, 0, 0, -5][0, -3, 0, 0, 0, 5] // [-2, 0, 0, 0, 0, 5][0, 3, 0, 0, 0,-5] // Whites eaten - 0, blacks eaten - 0 // You can use Arrays functionalities here, will make your life much easier... // Hints: Arrays.copyOfRange, Arrays.toString // ... return null; // TODO CHANGE } public int[] getBoard() { // ... return null; // TODO CHANGE } public boolean getWhitesTurn() { // ... return false; // TODO CHANGE } public void setBoard(int[] board) { // Use with caution, should be used only for debugging purposes! this.board = board; }

public boolean whiteStarts() { // You can give random boolean here, equivalent to randomly rolling 2 cubes and deciding from them // ... return false; // TODO CHANGE } public int[] roll2Cubes() { int[] cubes = new int[2]; // TODO CHANGE return cubes; } public boolean gameOver() { // ... return false; // TODO CHANGE } public boolean move(int position, int move) { int direction = this.whitesTurn ? 1 : -1; if (legalMove(position, move)) { // TODO CHANGE return true; } return false; } public boolean haveLegalMoves(int[] cubes) { // Any legal moves for the player // ... return false; // TODO CHANGE } public boolean legalMove(int startPosition, int move) { // ... return false; // TODO CHANGE } public int farthestStone() { // ... return -1; // TODO CHANGE } public boolean farthestStoneInLastQuadrant(int farthestStone) { // ... return false; // TODO CHANGE } public boolean outOfBoard(int position) { // ... return false; // TODO CHANGE } public void nextTurn() { // ... // TODO CHANGE } public void runGame() { while (!this.gameOver()) { int[] cubes = this.roll2Cubes(); this.cubesUsages[1] = this.cubesUsages[0] = (cubes[0] == cubes[1]) ? 2 : 1; // Move the board using legal moves rolled by the cubes: while (this.cubesUsages[0] > 0 || this.cubesUsages[1] > 0) { if (!this.haveLegalMoves(cubes)) break; System.out.print(this.whitesTurn ? "Whites turn ()" : "Blacks turn ()"); System.out.println(", Rolled " + cubes[0] + " " + cubes[1]); System.out.print("Insert position number: "); int choosenPosition = this.sc.nextInt(); System.out.print("Insert cube number (0 or 1): "); int cubeToUse = this.sc.nextInt(); if (cubeToUse < 0 || cubeToUse >= cubes.length) { System.out.println("Please select a cube from the range of 0 to " + (cubes.length - 1)); continue; } if (this.cubesUsages[cubeToUse] <= 0) { System.out.println("Can\'t use this cube again!"); continue; } int choosenMove = cubes[cubeToUse]; boolean moved = this.move(choosenPosition, choosenMove); if (moved) { this.cubesUsages[cubeToUse] -= 1; System.out.println(this); } else System.out.println("Illegal move!"); } this.nextTurn(); } System.out.println(this.whitesTurn ? "Black won!" : "White won!"); } public static void main(String[] args) { Backgammon bg = new Backgammon(); System.out.println(bg); bg.runGame(); } }
