为 Java 中的每个小功能创建方法是否会降低性能？

Question

我几乎一直在研究 Android 和 Java。我在这两方面的经验都处于中等水平。但每当我编写代码时，我都会在编程时尝试遵循并实现所有 OOP 概念，即使是针对小型应用程序或程序。

I have a question that does creating a METHOD for each functionality (data passing, data retrieval, calling subroutines in other classes, activities) is a good practice or a bad practice? And does creating lot of methods(modules) degrade performance?

非常感谢任何形式的帮助或解释。

提前致谢。

根据this and this, making more and more methods for everything is not a good idea in Android. In their words, "virtual method calls are expensive". They also recommend avoiding excessive use of design patterns and class hierarchies; see here and here。
