When writing an application(in java) that you intend to open source, is it generally a good idea to have a lot of getters & setters and make variables private? More specifically, if that were to be an android application, would the answer to the question above still hold?
编辑：如果你们能够给我一个具体原因，为什么它的更好，这将是真棒。
If you guys could give me a concrete reason as to why its better, that would be awesome.
推荐答案
如果你正在讨论的getter和放大器;结果 - ：在机器人，检查哪些Android文档告诉setter方法
<一href=\"http://developer.android.com/guide/practices/design/performance.html#internal_get_set\">Avoid内部getter / setter方法 结果
在Android上，这是一个坏主意。虚拟方法调用是昂贵，远远超过了实例字段查找。这是合理的，遵循共同的面向对象编程实践和在公共接口getter和setter，但是在类中，你应该总是直接访问域。
If you are discussing getters & setters in ANDROID, check what android documentation tell:-
Avoid Internal Getters/Setters
On Android, this is a bad idea. Virtual method calls are expensive, much more so than instance field lookups. It's reasonable to follow common object-oriented programming practices and have getters and setters in the public interface, but within a class you should always access fields directly.
