推荐答案

您的方法被标记为 private 因此它将无法从该类外部访问，将其更改为 public 或将其读取为其他修饰符： java中的访问修饰符 - Javatpoint [ ^ ]

Your method is marked as private hence it will not be accessible from outside that class, change it to public or read this for other modifiers : Access modifiers in java - Javatpoint[^]

您需要将您的课程视为公开课程而不是私人课程。 Private使它无法在自身之外访问，这将使其无法调用。

You need to have your class as public instead of private. Private makes it to where it cannot be accessed outside of itself, which would make it impossible to call on.
