private or protected5
以前我写class 除了公有的方法就是私有的方法。只要不是给别人用的都写成私有的
现在为了测试方便习惯把testCase跟测试对象放在一个包里，然后把方法都写成protected方便测试。
这种方法好吗，什么时候应该用私有方法，什么时候用protected方法呢？2008年7月23日 07:52

采纳的答案
你的需求不应该用protected。
protected只用于子类继承需要override的情况。
你的需求用默认的包访问权限即可。请记住java有4种可见性控制，private、public、protected以及什么都不加时的包访问权限。2008年7月24日 11:24

建议测试代码放到同一个包中，但最好放在不同的文件夹中。
例如在eclipse中，代码放到src中， 测试代码放到test中，包名可以相同.
如：com.abc.blabla
楼上说的对，protected是给之类继承时用的，如果不想给之类使用就用private。public的就不用说了。2008年7月24日 11:04

如果一个类是需要被继承的，而且他的方法，子类又用得到，就用protected
话说回来，要理解这个问题，需要了解面向对象中，对象之间的关系
一般来说，如果对象之间是依赖关系，用public
而聚合关系一般都用protected的
如果这个方法不想和外界打交道就是private
总的来说，private是自己用的，protected是给子类继承用的2008年7月23日 10:10
