问题描述
我正在Drjava做一个Tic Tac Toe游戏。我需要这方面的帮助。所以我不会把整个代码放在一个循环中，所以我不必一遍又一遍地打印相同的东西。
Hi, I am making a Tic Tac Toe game in Drjava. I need help with this thing. So i wont to put this entire code in a loop so I Dont have to keep printing the same thing over and over again.
<pre lang="Javascript">import java.util.Scanner;
public class TicTacToeArray {
public static void main(String[] args){
Scanner in = new Scanner(System.in);
int [] A1 = {0,1,2};
int [] A2 = {3,4,5};
int [] A3 = {6,7,8};
int [] A4 = {0,3,6};
int [] A5 = {1,4,7};
int [] A6 = {2,5,8};
int [] A7 = {0,4,8};
int [] A8 = {2,4,6};
System.out.println("Player #1: Please enter a number between 0-8");
int playerOne = in.nextInt();
if (playerOne == A1 [0]){
System.out.println(" | | ");
System.out.println(" X | 1 | 2 ");
System.out.println(" | | ");

推荐答案
模式，我的亲爱的，你必须寻找模式，模式无处不在（就像Maximillian Cohen所说的那样......）。
你有9块瓷砖，排列成3x3马赛克。我会在编写绘制瓷砖的功能时考虑这些模式，例如：
Patterns, my dear, you have to look for patterns, patterns are everywhere (like Maximillian Cohen would have said...).
You have 9 tiles, arranged in a 3x3 mosaic. I would consider such patterns while writing a function for drawing the tiles, e.g.
import java.util.Scanner;
public class TTT
{
public static void draw_tiles(int x)
{
int c, r; // r is the row number, c is the column number
for (r = 0; r < 3; ++r)
{
System.out.println(" | | ");
for ( c = 0; c < 3; ++c)
{
String sep, no;
int n = r * 3 + c;
sep = c < 2 ? "|" : "\n";
System.out.print(" ");
no = x == n ? "X" : String.valueOf(n);
System.out.print(no);
System.out.print(" ");
System.out.print(sep);
}
System.out.println(" | | ");
if ( r < 2 ) System.out.println("----------------------------------");
}
}
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.println("Player #1: Please enter a number between 0-8");
int playerOne = in.nextInt();
if ( playerOne >= 0 && playerOne <= 8)
draw_tiles(playerOne);
else
System.out.println("Try Again");
}
}
