推荐答案

[ ^ ]可能会给您一个想法.

this[^] might give you an idea.

我不太了解您的问题.如果您声明一个私有字段，那么您将无法在班级之外访问它.

如果您希望数组的大小可以动态更改，则应使用ArrayList.

I don''t really understand your question. If you declare a field private you can''t access it outside your class.

If you want an array with a size that can change dynamically, you should use a ArrayList.
