Loops 在另一个类中查找方法时找不到符号错误

我的代码有问题

我的任务是让我的代码滚动这两个骰子，我做了1000次，每次这两个骰子的总和是7，然后我计数到递增1。直到循环停止在1000。这是我的密码。我正在尝试从类PairOfDice访问getTotalFaceValue的方法

---

问题是什么，它与循环有什么关系？第一个问题是我试图访问PairOfDice.getTotalFaceValue；在主方法中，但由于某种原因，我一直得到一个错误。我试着做PairOfDice var=newpairofdice；但这不起作用，第二个问题是，在我访问getTotalFaceValue方法之后，我需要做一个循环，每个循环的和是7，我将使count var增加1。。顺便说一句，我所有的程序都在同一个文件中，用适当的编程语言标记它
