三子棋

三子棋

用到了三个类分别是MainTest、ThreeGame、ThreeGameImpl

1. MainTest类，主要用于写一些客户端的代码，用于测试

   public class MainTest {
   
   	public static void main(String[] args) {
   		ThreeGameImpl g1 = new ThreeGame();
   		String user1;
   		String user2;
   		String curUser;
   		int curCount = 0;
   		boolean flag = false;
   		g1.print();
   		Scanner s = new Scanner(System.in);
   		System.out.println("请输入一号玩家姓名：");
   		user1 = s.next();
   		System.out.println("请输入二号玩家姓名：");
   		user2 = s.next();
   		while(!flag){
   			curUser = (curCount++)%2==0?user1:user2;
   			System.out.println("请玩家下棋：(输入坐标：1,2等)");
   			String Loc = s.next();
   			int i = Character.getNumericValue(Loc.charAt(0));
   			int j = Character.getNumericValue(Loc.charAt(2));
   			while(g1.getXY(i, j)!=‘O‘){
   				System.out.println("该位置已有棋,请重新输入");
   				Loc = s.next();
   				i = Character.getNumericValue(Loc.charAt(0));
   				j = Character.getNumericValue(Loc.charAt(2));
   			}
   			flag = g1.putC(i, j);
   			if(flag){
   				System.out.println(curUser+"胜利！");
   				break;
   			}
   
   		}
   		s.close();
   		System.out.println("游戏结束！");
   //		System.out.println(‘#‘+‘#‘+‘#‘);
   //		System.out.println(‘*‘+‘*‘+‘*‘);
   	}
   
   }
   

2. ThreeGameImpl是一个抽线类，用于规范方法

   public abstract class ThreeGameImpl {
   	public abstract void print();
   	public abstract boolean check();
   	public abstract boolean putC(int i,int j);
   	public abstract void init();
   	public abstract char getXY(int i,int j);
   }
   
   

3. ThreeGame是具体实现

   public class ThreeGame extends ThreeGameImpl{
   	private char[][] C;
   	private char[] style= {‘#‘,‘*‘};
   	private int count = 0;
   	public ThreeGame(){
   		C = new char[3][3];
   		init();
   		System.out.println("游戏开始！");
   	}
   
   	@Override
   	public void print() {
   		for(int i = 0;i<3;i++){
   			for(int j = 0;j<3;j++){
   				System.out.print(C[i][j]+"  ");
   			}
   			System.out.println();
   		}
   		
   	}
   
   	@Override
   	public boolean check() {
   		for(int i = 0;i<3;i++){
   			if(C[i][0]+C[i][1]+C[i][2] == 105 || C[i][0]+C[i][1]+C[i][2] == 126) return true;
   			if(C[0][i]+C[1][i]+C[2][i] == 105 || C[0][i]+C[1][i]+C[2][i] == 126) return true;
   		}
   		if(C[0][0]+C[1][1]+C[2][2] == 105 || C[0][0]+C[1][1]+C[2][2] == 126) return true;
   		if(C[0][2]+C[1][1]+C[2][0] == 105 || C[0][2]+C[1][1]+C[2][0] == 126) return true;
   		return false;
   	}
   
   	@Override
   	public boolean putC(int i,int j) {
   		C[i][j] = style[(count++)%2];
   		print();
   		return check();
   	}
   
   	@Override
   	public void init() {
   		for(int i = 0;i<3;i++){
   			for(int j = 0;j<3;j++){
   				C[i][j] = ‘O‘;
   			}
   		}
   	}
   
   	@Override
   	public char getXY(int i, int j) {
   		return C[i][j];
   	}
   
   }
