嘿,我正在完成这个井字游戏项目,但我的 checkWin 方法中的棋盘类中有一个错误,其中 Winner = board[0][i]; Int 和 String 会出现不兼容错误。我已经使用 Integer.toString() 命令在我的另一条板上修复了此问题,但它对此不起作用。有任何想法吗?这是 checkWin 方法的代码。
public boolean checkWin()
{
{
int i; // i = column
int j; // j = row
int count;
int winner;
winner = empty; // nobody has won yet
// Check all rows to see if same player has occupied every square.
for (j = 0; j < boardSize; j ++)
{
count = 0;
if (board[j][0] != Integer.toString(empty))
for (i = 0; i < boardSize; i ++)
if (board[j][0] == board[j][i])
count ++;
if (count == boardSize)
winner = (board[j][0]);
}
// Check all columns to see if same player has occupied every square.
for (i = 0; i < boardSize; i ++)
{
count = 0;
if (board[0][i] != Integer.toString(empty))
for (j = 0; j < boardSize; j ++)
if (board[0][i] == board[j][i])
count ++;
if (count == boardSize)
winner = board[0][i];
}
// Check diagonal from top-left to bottom-right.
count = 0;
if (board[0][0] != Integer.toString(empty))
for (j = 0; j < boardSize; j ++)
if (board[0][0] == board[j][j])
count ++;
if (count == boardSize)
winner = board[0][0];
// Check diagonal from top-right to bottom-left.
count = 0;
if (board[0][boardSize-1] != Integer.toString(empty))
for (j = 0; j < boardSize; j ++)
if (board[0][boardSize-1] == board[j][boardSize-j-1])
count ++;
if (count == boardSize)
winner = board[0][boardSize-1];
// Did we find a winner?
if (winner != empty)
{
if (winner == Xstr)
System.out.println("\nCongratulations! P1 You win!");
else if (winner == Ostr)
System.out.println("\nCongratulations! P2 You win!");
else
return true;
}
}
最佳答案
winner = board[0][i];
winner
是 int 基元类型,board
是多维字符串数组。
您正在尝试为 int 分配一个字符串,因此Int 和 String 会出现不兼容的错误。
String[][] board;
其索引处有字符串,当您尝试访问board[0][i]
时,您正在检索字符串。
如果您的棋盘数组包含数字的字符串表示形式,例如
boards= {{"1"},{"2"}};
然后使用 Integer.parseInt() ,它将 String 作为参数并返回一个 Integer。
winner = Integer.parseInt(board[0][i]);
但请注意,如果传递给 parseInt 的字符串不是字符串的有效整数表示,它将抛出 NumberFormatException。
