今天写了一个Java打印五子棋程序：

//五子棋
package com.dream.Test;
import java.util.Scanner;
public class Test01 {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		int len = 20;
		String black = "━●━";
		String white = "━○━";
		String[] seStr = {" 1.", " 2.", " 3.", " 4.", " 5.", " 6.", " 7.", " 8.", " 9.", "10.","11.", "12.", "13.", "14.", "15.","16.", "17.", "18.", "19.", "20."};
		//初始化棋盘
		String[][] goBang = new String[len][len];
		for (int i = 0; i < goBang.length; i++) {
			for (int j = 0; j < goBang.length; j++) {
				goBang[i][j] = "━╋━";
			}
		}
		//打印棋盘
		printChess(goBang, seStr);
		//落子
		boolean bool = false;//白子false,黑子true
		while(true){
			String isBW = bool ? "黑子" : "白子";
			System.out.println("请输入" + isBW + "坐标");
			int xChess = scan.nextInt();
			int yChess = scan.nextInt();
			if(xChess <= len && yChess <= len && goBang[xChess][yChess] == "━╋━"){
				goBang[xChess][yChess] = bool ? black : white;
				bool = !bool;
			}else{
				System.out.println("输入错误，请重新输入：");
			}
			printChess(goBang, seStr);
		}
	}
	//打印棋盘
	public static void printChess(String[][] goBang, String[] seStr){
		for (int i = 0;  i < goBang.length; i++) {
			for (int j = 0; j < goBang.length; j++) {
				System.out.print(goBang[i][j]);
			}
			System.out.println(seStr[i]);
		}
		for (String string : seStr) {
			System.out.print(string);
		}
		System.out.println();
		
	}
}
