如何在连接四个游戏中正常输出玩家

Question

这是我的板类

public class Board {
char[][] grid;
int width;
int height;
int count;
char player;

public Board(int height, int width){
count = 0;
grid = new char[height][width];
this.width = width;
this.height = height;
for(int i = 0; i < height; i++) {
for(int j = 0; j < width; j++){
if(i == 0 && j == 0){

grid[i][j] = '┌';
}
else if(j % 2 == 1) {
grid[i][j] = '─';
}
else if (i == 0 && j == width - 1){
grid[i][j] = '┐';
}
else if (i == height-1 && j == 0){

grid[i][j] = '└';
}
else if (i == height - 1 && j == width - 1){
grid[i][j] = '┘';
}
else if (i == 0){
grid[i][j] = '┬';
}
else if (j == 0){

grid[i][j] = '├';
}
else if (i == height - 1){
grid[i][j] = '┴';
}
else if (j == width - 1){
grid[i][j] = '┤';
}
else  
grid[i][j] = '┼';
}
}
}
public void print(){
for(int i=0; i<height; i++){
for(int j=0; j<width; j++)
System.out.print(grid[i][j]);
System.out.println();
}
}

下面是board类的put函数。问题出在put函数上。您必须从selectline功能中输入一行，然后让播放器出现在所需的行上。然而，无论我多么努力地修改条件语句，它都只出现在第一行。如何修改put函数的条件语句？

public void put(SelectLine setLine) {
int y=setLine.getY();
int x = grid.length-1;
if(count%2 == 0) {
player = '●';   
}
else {
player = '○';
}


for(int i = grid.length-1; i >=0; i--) {
if(grid[i][(y-1)*2] != player) {
grid[i][(y-1)*2] = player;
count++;
break;
}
}

System.out.println("────────" + player + "'s Turn ────────");
this.print();       
}
}

public class SelectLine {
int line;
public void input(){

System.out.print("Select Line : ");
Scanner sc = new Scanner(System.in);
line = sc.nextInt();
}
public int getY(){
return line;
}

}我们的目标是像下图一样不断地堆积起来。在此处输入图像描述

如下修改SelectLine类：

class SelectLine {
int line;
public int input(){

System.out.print("Select Line : ");
Scanner sc = new Scanner(System.in);
line = sc.nextInt();
return line;
}
public int getY(){
return input();
}

不过，您需要考虑到用户可能会输入负值或超出网格大小的值。

谨致问候。

import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Board b = new Board(10, 10);
b.print();
b.put(new SelectLine());
System.out.println("Hello World");
}
}
class Board {
char[][] grid;
int width;
int height;
int count;
char player;

public Board(int height, int width){
count = 0;
grid = new char[height][width];
this.width = width;
this.height = height;
for(int i = 0; i < height; i++) {
for(int j = 0; j < width; j++){
if(i == 0 && j == 0){

grid[i][j] = '┌';
}
else if(j % 2 == 1) {
grid[i][j] = '─';
}
else if (i == 0 && j == width - 1){
grid[i][j] = '┐';
}
else if (i == height-1 && j == 0){

grid[i][j] = '└';
}
else if (i == height - 1 && j == width - 1){
grid[i][j] = '┘';
}
else if (i == 0){
grid[i][j] = '┬';
}
else if (j == 0){

grid[i][j] = '├';
}
else if (i == height - 1){
grid[i][j] = '┴';
}
else if (j == width - 1){
grid[i][j] = '┤';
}
else  
grid[i][j] = '┼';
}
}
}
public void print(){
for(int i=0; i<height; i++){
for(int j=0; j<width; j++)
System.out.print(grid[i][j]);
System.out.println();
}
}

public void put(SelectLine setLine) {
int y=setLine.getY();
int x = grid.length-1;
if(count%2 == 0) {
player = '●';   
}
else {
player = '○';
}


for(int i = grid.length-1; i >=0; i--) {
if(grid[i][(y-1)*2] != player) {
grid[i][(y-1)*2] = player;
count++;
break;
}
}

System.out.println("────────" + player + "'s Turn ────────");
this.print();       
}
}

class SelectLine {
int line;
public int input(){

System.out.print("Select Line : ");
Scanner sc = new Scanner(System.in);
line = sc.nextInt();
return line;
}
public int getY(){
return input();
}
}
