Problem Statement -

Simple rock paper scissors game. 

The game played between a player and a computer which chooses randomly.

The player should be able to interact with the application to choose one of the available actions (Rock, Paper, Scissors) using command line where 0 means ROCK, 1 means Paper, 2 means Scissor.

The interaction can happen via a terminal prompt.

Any player should be able to play any number of games in one session.

First Input should be the Name of the player and we will start taking the input for Rock/Paper/Scissor.

Detail about the Implementation -

There will be two Service -

GameSvc - which execute the game whenever player plays the game

ComputerSvc - which plays the game as a computer. It generates its own GameToken

There are other couple of class whose details you can find below -

Player - Model Class for the player

RockPaperScissorExecutor- which will execute the gameToken and finds which gameToken has priority over other token.

Flow of Game-

Step 1. Game start by taking the player's name. We initialize the game here by Calling initializing the GameSvc.

Step 2. We take the player's desired token as a input. Here instead of taking String as a input, I have taken the number which is internally map to the various Tokens, Like 0 - ROCK, 1 - PAPER, 2 - SCISSOR

Step 3. we call the GameSvc's play method with the player's Desired input as a argument

Step 4. GameSvc do following things -

• Do a Precondition Check: Check if player has given the valid Input i.e. anything from {0 to 2}
• Update the playerOne Token and calls the ComputerSvc to get the computer's token and update the computer's info in PlayerTwo object
• Then it call the RockPaperScissorExecutor to execute the game to Get the final result of the Game.
• Then It prints the result of the Game

Step 5 - RockPaperScissorExecutor internally calls the GameToken Executor to find the result at each GameToken Level.

Flow Ends Here.
