自编的java黑白棋小游戏为什么落子时会报错？

取消只看楼主收藏回复

在知道上也发了同样的问题。。。但是知道既不能发度盘链接，也没法发图片，所以来贴吧请求各位大佬帮助

报错图镇楼，楼下发详细代码和完整代码压缩包度盘链接

完整报错代码：

立即查看

我自己觉得可能是错因的几个关键位置代码:
①鼠标监控器获取鼠标点击位置
addMouseListener(new MouseAdapter(){
@Override
public void mousePressed(MouseEvent e){
if(!isGameOver){
int x=e.getX();
int y=e.getY();
if((x>=30&&x<=350)&&(y>=40&&y<=360)){
int col=Math.round((x-30)/40.0f);
int row=Math.round((y-40)/40.0f);
if(BWBoard.makeMove(row,col,isBlackTurn)){
isBlackTurn=!isBlackTurn;
repaint();
}
}
}
}
});
}

②判断能否下子
public boolean makeMove(int row, int col, boolean isBlack) {
/*
* 判断能否下子
*/
if ((board[row][col] == BoardState.EMPTY)&&(ifReverse(row,col,isBlack))) {
board[row][col] = isBlack ? BoardState.BLACK : BoardState.WHITE;
lastCol=col;
lastRow=row;
return true;
}
return false;
}

③判断假设下子后能否翻转
public boolean ifReverse(int row, int col, boolean isBlack) {
/*
* 判断本次下子是否产生翻转
*/
boolean ifReverse=false;
BoardState state=isBlack?BoardState.BLACK:BoardState.WHITE;
if(judgeRow(row,col,state)||judgeCol(row,col,state)||judgeX1(row,col,state)||judgeX2(row,col,state))
ifReverse=true;
return ifReverse;
}

④逐个方向判断能否翻转（这里只给出竖向判断的，其他方向的代码和竖向都差不多，需要全部方向可以看完整代码压缩包）
public boolean judgeRow(int row, int col,BoardState state) {
/*
* 竖排能否反转
*/
int rowIndex=row;
boolean judge=false;
boolean judgeUp=true;
boolean judgeDown=true;
if(board[row+1][col]==state)
judgeUp=false;//此子相邻上方为同色则上方必然无法反转
if(board[row-1][col]==state)
judgeDown=false;//此子相邻下方为同色则下方必然无法反转
while((rowIndex-1>=0)&&judgeDown) {
if(board[rowIndex-1][col]==state)
judge=true;
rowIndex-=1;
}
while((rowIndex+1<=board.length)&&judgeDown) {
if(board[rowIndex+1][col]==state)
judge=true;
rowIndex+=1;
}
return judge;
}
