In this game, of a 4x4 board. The game will first ask the user to enter their name and age. Following that, a 4x4 board will be displayed where each space is marked by a letter (from A P). The program will then prompt the user to select a space and accordingly reveal whether a rabbit was hiding in that space or not. If it is, that space becomes marked with X. Otherwise, the space becomes empty (no letter is displayed in the space). In the screenshot below shows the areas where no rabbit was found by the user, 1) import java.util.Random; import java.util.Scanner; import cmps251.homework2.Board; import cmps251.homework2.Game; import cmps251.homework2.Player; /** * DO NOT MODIFY THIS CODE * * This code is only to help you run the code * You can verify the functionality by logging in to * oryx.qu.edu.qa (ssh).
