8阶段项目：五子棋
8.1-技术实现
1.静态变量
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。
2.静态方法
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。
/*** 静态变量和静态方法*/
public class staticTest {//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);
// System.out.println("张三");
// System.out.println("男");
// System.out.println("20");
// System.out.println("张三");
// System.out.println("男");
// System.out.println("20");show();}public static void show(){System.out.println("张三");System.out.println("男");System.out.println("20");}

8.2-棋盘制作
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，然后寻找落子位置的特征
/*** 五子棋*/
public class Gobang {public static void main(String[] args) {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
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);}}System.out.println();if(i<chessboard.length-1){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(" 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);}}System.out.println();if(i<chessboard.length-1){System.out.println(" │ │ │ │ │ │ │ │ │ │");}}}}
2.落子
a.玩家A、B会交替落子
public class Gobang {public static char[][] chessboard={{'┌','┬','┬','┬','┬','┬','┬','┬','┬','┐'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'└','┴','┴','┴','┴','┴','┴','┴','┴','┘'}};public static String separator="─────";public static void main(String[] args) {showChessboard();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：");}}public static void showChessboard(){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);}}System.out.println();if(i<chessboard.length-1){System.out.println(" │ │ │ │ │ │ │ │ │ │");}}}}
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;public class Gobang {public static char[][] chessboard={{'┌','┬','┬','┬','┬','┬','┬','┬','┬','┐'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'├','┼','┼','┼','┼','┼','┼','┼','┼','┤'},{'└','┴','┴','┴','┴','┴','┴','┴','┴','┘'}};public static String separator="─────";public static char pieceA='○';public static char pieceB='■';public static void main(String[] args) {showChessboard();int totalPosition=chessboard.length*chessboard[0].length;Scanner sc=new Scanner(System.in);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:");while(true){//保证落子成功的一个循环if(sc.hasNextInt()){//检测Scanner中是否有输入的数据并且判断是否为整数，如果没有数据，就需要从控制台输入int position=sc.nextInt();if(position>=0&&position<totalPosition){char currentPiece=times%2==0?pieceA:pieceB;int row=position/chessboard.length;//位置除以棋盘数组的长度得到行号int col=position%chessboard[0].length;//位置取模棋盘数组的总列数得到列号if(chessboard[row][col]==pieceA||chessboard[row][col]==pieceB){System.out.println("非法落子，请重新选择落子位置");continue;}else{chessboard[row][col]=currentPiece;break;}}else{System.out.println("非法落子，请重新选择落子位置");}}else{System.out.println("非法落子，请重新选择落子位置");sc.next();//将Scanner中存储的数据取出，防止死循环}}//落子完成后，棋盘需要重新展示showChessboard();}}public static void showChessboard(){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);}}System.out.println();if(i<chessboard.length-1){System.out.println(" │ │ │ │ │ │ │ │ │ │");}}}}
c.落子完成后，需要校验是否获胜
