“猪”游戏Java程序出错

Question

我正在尝试编写一个程序来玩游戏猪，我两次得到这个错误，但我不知道为什么：“错误：无法找到符号扫描器sc=new Scanner（system.in）；

非常感谢任何帮助。我对写代码很陌生，所以请你好心。：）另外，忽略奇怪的间距...在我的程序中它做得很正确，但我有困难让它正确地适合这里。

class Die {

    private final int MAX = 6;

        faceValue = (int) (Math.random() * MAX) + 1;
        return faceValue;
    }

    public void setFaceValue(int value) {
        if (value > 0 && value <= MAX) {
            faceValue = value;
        }
    }

    public int getFaceValue() {
        return faceValue;

您指的是java.util.scanner而不是scanner。导入java.util.scanner；。
