Question
For this project, you will submit two .java files. You will need to run two classes simultaneously for this activity. Make sure you have a compiler that is capable of this.
The game we’re going to make will be a simple competitive Memory game. To begin, the Server will create a 4x4 grid of 16 integers – 1 through 8. These integers will be stored in a 2D array and held on the Server. Neither Client should be given access to this array. Instead, the Server will ask the first player for a grid tile (row and column). Then, the Server will display the tile that the user has chosen and then ask the same player for another grid tile. If the two match, they remain revealed. If they don’t, they are hidden again. Afterwards, the process should repeat with the second player this time. If either player reveals a match, they are given a point (also kept only on the Server). At the end of the game, the player with the highest number of points wins (or both players tie if their scores are the same).
To simplify the process of sending data and to keep the data flow open, you might want to create a method on your Server to return a single String that represents the current state of the board and send that to each Client when the need arises. Be sure to include the players’ scores in the String that you send. Also remember to catch any possible exceptions, close all forms of I/O, and prevent the connection from being terminated early.
