java - FC_COLS 的原始类型 int 没有字段 inBlockSize

Question

我在 lastStartCol = FC_COLS – inBlockSize; 上收到此错误，并且在 lastStartCol = ECONOMY_COLS – inBlockSize; 上收到类似的错误。也不确定我的老师希望我用 for 语句做什么。简单的答案表示赞赏。

//确定lastStartCol，行中给定 block //大小的最后一个合法起始列。

if(inRow < FC_ROWS)
    lastStartCol = FC_COLS – inBlockSize;
else
    lastStartCol = ECONOMY_COLS – inBlockSize;


for(int startCol = 0; startCol <= lastStartCol; startCol++)
{
    ...

Answer 1

我的理解是打字错误。

尝试像此行lastStartCol = FC_COLS - inBlockSize; 首先删除此-，然后再次从键盘输入减号。

也从这一行执行上述操作lastStartCol = ECONOMY_COLS - inBlockSize;

或者

尝试用下面的代码替换您的代码行。

if(inRow < FC_ROWS)
    lastStartCol = FC_COLS - inBlockSize;
else
    lastStartCol = ECONOMY_COLS - inBlockSize;
