Java实现五子棋（保姆级教学）
发布时间：2024年01月15日
阶段项目 五子棋
需求说明
五子棋棋盘是一个10 X 10的棋盘，五子棋玩家共2个（这里分别称为A和B），A在棋盘上落子后，B再落子，以此往复，直到一方胜利或者棋盘空间用完为止。判断胜利的条件是一条直线或者任意斜线上同时存在A或B的连续5颗棋子（见下图）。
技术实现
1.静态变量
语法
public static 数据类型 变量名 = 变量值;
解释说明
静态变量只能定义在类中，不能定义在方法中。静态变量可以在static修饰的方法中使用，也可以在非静态的方法中访问。主要解决在静态方法中不能访问非静态的变量的问题。
2.静态方法
语法
public static 返回值类型 方法名(){
}
解释说明
静态方法就相当于一个箱子，只是这个箱子中装的是代码，需要使用这些代码的时候，就把这个箱子放在指定的位置即可。
示例
/**
* 静态变量和静态方法
*
*/
public class StaticText {
//静态变量只能定义在类中，不能定义在方法中
public static String name = "张三";
public static void main(String[] args) {
System.out.println(name);
show();//用下面定义的show方法来打印信息
}
public static void show() {
System.out.println("张三");
System.out.println("男");
System.out.println("20");
}
}
实现步骤分析
1.制作棋盘
a.使用输入法中的制表符在控制台直接打印出棋盘，然后寻找落子的特征
（制表图形作者用的是搜狗输入法—符号大全—制表符）
System.out.println("┌────┬────┬────┬────┬────┬────┬────┬────┬────┐");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("├────┼────┼────┼────┼────┼────┼────┼────┼────┤");
System.out.println("│ │ │ │ │ │ │ │ │ │");
System.out.println("└────┴────┴────┴────┴────┴────┴────┴────┴────┘");
b.利用二维数组重新制作棋盘
/**
* 五子棋
*
*/
public class Gobang {
public static char[][] chessboard = {
{'┌','┬','┬','┬','┬','┬','┬','┬','┬','┐'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'└','┴','┴','┴','┴','┴','┴','┴','┴','┘'}
};
public static String separator = "────";
public static void main(String[] args) {
System.out.println(" 0 1 2 3 4 5 6 7 8 9");
for(int i=0; i<chessboard.length; i++){//外层循环控制行
System.out.print(i + " ");
for(int j=0; j<chessboard[i].length; j++){//内层循环控制列
if(j == chessboard[i].length - 1){//最后一列
System.out.print(chessboard[i][j]);
} else {
System.out.print(chessboard[i][j] + separator);//使用print打印，不换行
}
}
System.out.println();//打印完一行后换行
if(i < chessboard.length-1) {//排除最后一行
System.out.println(" │ │ │ │ │ │ │ │ │ │");
}
}
}
}
c.棋盘在玩家使用过程中会反复展示，需要使用方法来进行优化
public class Gobang {
public static char[][] chessboard = {
{'┌','┬','┬','┬','┬','┬','┬','┬','┬','┐'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},
{'└','┴','┴','┴','┴','┴','┴','┴','┴','┘'}
};
public static String separator = "────";
public static void main(String[] args) {
showChessboard();
}
public static void showChessboard() {
System.out.println("========================================================");
System.out.println(" 0 1 2 3 4 5 6 7 8 9");
for(int i=0; i<chessboard.length; i++){//外层循环控制行
System.out.print(i + " ");
for(int j=0; j<chessboard[i].length; j++){//内层循环控制列
if(j == chessboard[i].length - 1){//最后一列
System.out.print(chessboard[i][j]);
} else {
System.out.print(chessboard[i][j] + separator);//使用print打印，不换行
}
}
System.out.println();//打印完一行后换行
if(i < chessboard.length-1) {//排除最后一行
System.out.println(" │ │ │ │ │ │ │ │ │ │");
}
}
}
}
2.落子
a.玩家A、B会交替落子
int totalPosition = chessboard.length * chessboard[0].length;
for(int times=0; times < totalPosition; times++){
System.out.println(times % 2 == 0 ? "请玩家A落子" : "请玩家B落子");
}
b.落子位置必须是0~100之间的整数，且不能使用已经存在棋子的位置
import java.util.Scanner;

while(true) {//保证落子成功才能够退出循环

}

}

}
}
//落子完成后，棋盘需重新展示
showChessboard();
}
}
public static void showChessboard() {
System.out.println("========================================================");
System.out.println(" 0 1 2 3 4 5 6 7 8 9");
