我的代码将显示我这不是一个可接受的输入.如果我插入负数.然后继续提示输入.但它继续计算.这是我的代码中包含错误的一部分.但我没有看到.

public static boolean checkOctal()
{
    boolean b = true;
    if (oct < 0 && oct > 99999999 )
    {
        b = false;
        System.out.println("That is not an acceptable input.");
    }
    int tmp;
    int tmp1 = oct;
    while (tmp1 > 0)
    {
        tmp = tmp1 % 10;
        tmp1 = tmp1 / 10;
        if (tmp >= 0 && tmp < 8)
        {
            continue;
        } else
        {
            b = false;
            break;
        }
    }
    return b;

}

我正在努力构建一个Sudoku程序.当我编译时,我有很多错误,但我看不出它们实际上是什么错误.
