捆绑包类路径头更有趣。
您可以在代码的任何地方导入包、类等，它们的作用域限于导入它们的文件。
You can import packages, classes, etc. anywhere in the code, and they are scoped to where you import them.
然后您可以继续进行分析，把范围缩减到哪个包、类，直到找到导致问题的方法。
Then you can continue narrowing down to determine which package, class, and, finally, which method is causing the problem.
