Overall stuff:
Overall this code imports two libraries in java: java.util.Scanner; and java.lang.Math;. These libraries allow for extra functionality, the Scanner allowing for user input, and math allowing for random numbers.
The public class ConsoleGame is the primary object, that holds all of the functions that can be used. Thus, when we create a new ConsoleGame, it creates with all of the inside methods, such as horlgame, rps, and ticTacToe.
Console Game
In the console game constructor, there are a couple of additions in order to allow for selection. When the object is created, a new scanner is created ot read user input, by first creating a choice, and then posing that choice through the action method. The action method is then called using this, which is similar to the self in python, which is a reference to the object itself. By doing this, the code is able to gather the player input about which game they chose. The code then uses an exception in a try/catch block in order to ensure all input is valid. The scanner is then closed to prevent data loss.
Higher or Lower Game Logic
Higher and lower is relatively simple to understand algorithmically. First, the computer selects a random number (int randomG = (int) (Math.random() * 8) + 1;) and creates a scanner to allow for user input again. It then allows for an integer guess, then loops through at least three times (the game allows you three guesses). It then follows the algorithm that:
- If it is equal –> break, you win
- If it is greater –> output that it is greater
- if it less than –> output it is less than
- Allow for another guess
^ This loops three times
After the process, it then quits, allowing for the scanner to be closed to preserve data.
Rock Paper Scissors Logic
Rock Paper Scissors operates pretty simply as well. Once again, a scanner is created, and a random number is created (multiplied by 3 in order to choose a random option between r p and s). Then, it evaluates the following logic depending on the user selection
- If user chose rock
- If computer chose 1 (paper)
- Computer wins
- If computer chose 2 (scissors)
- Player wins
- Else (computer choses rock)
- Draw
- If computer chose 1 (paper)
- If user chose paper
- If computer chose 1 (paper)
- Drqw
- If computer chose 2 (scissors)
- Computer wins
- Else (computer choses rock)
- Player wins
- If computer chose 1 (paper)
- If user chose scissors
- If computer chose 1 (paper)
- Player wins
- If computer chose 2 (scissors)
- Draw
- Else (computer choses rock)
- Computer wins
- If computer chose 1 (paper)
It also validates the input, in order to ensure that all input is valid.
After this, it closes the scanner to prevent data loss.
Tic Tac Toe (T)logic
Overall
In order to win, the code specifies all specific combinations of victory (8). It then checks the board against each individual combo in order to check if that combo exists. If it does, then one player is declared the winner.
The code also creates a scanner, and also a java array as an abstraction of the board (String[] board = {"1", "2", "3", "4", "5", "6", "7", "8", "9"};). This creates the board. When a move is declared, the respective area of board is replaced with either an X or an O based on the respective piece declared as the player.
PVP
In a PVP game, each player is given an opportunity to make a move, and then each individual piece of the board is replaced. Then the board is compared to each combo, and a winner is declared when each of the three is called
PVE
In a PVE game, the computer is given a random number to place their piece, and then the player is allowed to place a piece. Then the board is compared to each combo, and a winner is declared when each of the three is called. Then it quits
