门实例代码展示-----五子棋（面向对象版）

1.建立Gobang对象

package com.Xu.Gobang;

public class Gobang {
	public static final String BAI = "○";
	public static final String HEI = "●";
	public static final String XX = "+";
	static String[] nums = {" ","⒈","⒉","⒊","⒋","⒌","⒍","⒎","⒏","⒐","⒑","⒒","⒓","⒔","⒕","⒖","⒗","⒘","⒙","⒚","⒛"};
	
	
//初始化，载入棋盘初始数据
	public  void getGobang(String[][] a){
		for(int i=0;i<15;i++){
			for(int j=0;j<15;j++) {
				if(i==0) {
					a[i][j]=nums[j];
				}
				else if(j==0&&i!=0) {
					a[i][j]=nums[i];
				}
				else a[i][j]=XX;
			}
		}
	}
		
	//判断落子位置是否符合规则
	public boolean islocation(boolean flag,int x,int y,String[][] a)
	{
		if(x<1||y<1||x>=15) {
			System.out.print("坐标不存在\n");
			return false;
		}
		else if(a[x][y]!=XX) {
			System.out.print("坐标已被占用\n");
			return false;
		}
		else return true;
	}
	
	//刷新棋盘，打印棋盘
	public void printGobang(String[][] a) {
		for(int i=0;i<15;i++)
		{
			for(int j=0;j<15;j++)
				System.out.print(" "+a[i][j]);
			System.out.print("\n");
		}
	}
	//确定落子颜色
	public void Move(boolean flag,int x,int y,String[][] a)
	{
		if(flag)
		a[x][y]=HEI;
		else
		a[x][y]=BAI;
	}
	//判断是否分出了胜负
	public boolean isVictory(int x,int y,String[][] a)
	{
		System.out.print("已输入"+a[x][y]);
		System.out.print("\n");
		int p=1;
		int max=x,may=y;
		while(max>=1&&a[x][y]==a[--max][may])
		{
			p++;
		}
		max=x;
		while(max<15&&a[x][y]==a[++max][may])
			p++;
		max=x;
		if(p>=5) return true;
		else p=1;
		//xxxxxxx
		
		
		while(a[x][y]==a[max][--may]&&may>=1)
			p++;
		may=y;
		while(a[x][y]==a[max][++may]&&may<15)
			p++;
		may=y;
		if(p>=5) return true;
		else p=1;
		//yyyyyyyy
		
		
		while(a[x][y]==a[--max][--may]&&max>=1&&may>=1)
			p++;
		max=x;
		may=y;
		while(a[x][y]==a[++max][++may]&&max<15&&may<15)
			p++;
		max=x;
		may=y;
		if(p>=5) return true;
		else p=1;
		//xxxxxyyyyy
		
		
		while(a[x][y]==a[--max][++may]&&max>=1&&may<15)
			p++;
		max=x;
		may=y;
		while(a[x][y]==a[++max][--may]&&max<15&&may>=1)
			p++;
		max=x;
		may=y;
		if(p>=5) return true;
		else p=1;
		//yyyyyxxxxx
		return false;
		
	}
}

2.写测试类运行Gobang对象

package com.Xu.Gobang;

import java.util.Scanner;

public class Test {
	
	boolean isBlack = true; 
	public static void main(String[] args)
	{	
		Gobang gobang = new Gobang();
		int sum=16;
		String a[][]=new String[sum][sum];
		
		Scanner reader=new Scanner(System.in);
		//初始化棋盘
		gobang.getGobang(a);
		System.out.print("游戏开始\n");
		
		//打印棋盘
		gobang.printGobang(a);
		
		
		int x,y;//记录输入坐标
		boolean flag=true;
		while(true)
		{
			System.out.println("请"+(flag?"黑":"白")+"棋落子");
			System.out.print("请输入落子坐标X，输入-1结束游戏");
			x=reader.nextInt();
			System.out.print("请输入落子坐标y，输入-1结束游戏");
			y=reader.nextInt();
			if(x==-1||y==-1) break;

			
			if(gobang.islocation(flag,x,y,a)) {
				gobang.Move(flag,x,y,a);
				if(gobang.isVictory(x,y,a)) {
					gobang.printGobang(a);
					System.out.print(((flag)?"黑":"白")+"棋获胜！！游戏结束！\n");
					break;
				}
				else {
					flag=!flag;
					gobang.printGobang(a);
				}
				
			}
			else{
				continue;
			}
		}
	}
}
