问题描述

我一直致力于在命令行上使用简单的Tic-Tac-Toe游戏的项目。

代码工作正常但是它的所有java文件都知道这是多么完全不可靠所以我希望将它分解为类，所以我的代码是多个java文件而不是一个。 />


任何人都想帮我解决这个问题。破坏了我的脑袋:)



代码：

Ive been working on a project that is a simple Tic-Tac-Toe game on the command line.
The code works fine but its all one java file and I know how completely unreliable this is so I'm hoping to break it up into classes so my code is numerous java files rather than one .

Anyone want to help me break this up. Been wrecking my head :)

code :

import java.util.Scanner;

public class test3
{
	//Declares co-ordinates of different available moves
	static int A1, A2, A3, B1, B2, B3, C1, C2, C3;
	
	static Scanner sc = new Scanner(System.in);
	
	public static void main(String[] args)
	{
	System.out.println();
	System.out.println();

	//Prints layout of board so user knows what each section is named
   System.out.println("A1|A2|A3|");
   System.out.println("---------");
   System.out.println("B1|B2|B3|");
   System.out.println("---------");
   System.out.println("C1|C2|C3|");
   
   //Declares both the string for both the player and the computer.
   String prompt = "Welcome to our X and O's game . Please take your first go: ";
		String playerMove = "";
		String cpuMove = "";
		boolean gameIsDecided = false;

		//Because there is only 9 squares , the max amount of plays is 9.
		//The use of the counter keeps track of this
		
		for (int i = 1; i <=9; i++)
		{
			//Gives the human player its identity(1) and sets out what happens if player wins

			playerMove = getMove(prompt);
			updateBoard(playerMove, 1);
			displayBoard();
			if (isGameDecided())
			{
				System.out.println("Congratulations , you have beaten me!!");
				gameIsDecided = true;
				break;
			}

			// Gives the human player its identity(2) and sets out what happens if computer wins
			if (i < 9)
			{
				cpuMove = getCpuMove();
				System.out.println(cpuMove);
				updateBoard(cpuMove, 2);
				displayBoard();
				if (isGameDecided())
				{
					System.out.println("Unlucky , I win. Better luck next time :");
					gameIsDecided = true;
					break;
				}
				prompt = "Take your next go: ";
				i++;
			}
		}
		if (!gameIsDecided)
			System.out.println("So nothing can separate us , the game is a draw !!");
	}

我的尝试：



我已经搞砸了它并尝试将其分解但到目前为止我没有运气。如果有人能告诉我如何分解它将会很好

What I have tried:

Ive messed around with it and tried breaking it down but so far I've had no luck. If anyone can show me how I could break it up that would be great

推荐答案

首先通过定义每个类，它包含哪些属性以及什么属性将它分解为单独的类它执行的方法。请参阅课程：类和对象（Java教程 - 学习Java语言） [< a href =http://docs.oracle.com/javase/tutorial/java/javaOO/index.htmltarget =_ blanktitle =New Window> ^ ]。

You break it into separate classes by first defining each class, what properties it contains and what methods it performs. See Lesson: Classes and Objects (The Java Tutorials - Learning the Java Language)[^].
