java 中，对于某些严谨的程序，读前线的控制应该引起足够的重视，以前在写代码的时候，追求方便和速度，将几乎所有的方法都设置为public，在<Thinking in java>中，将前端程序员与类开发者分开，我到现在还不明白为什么要这样做。如果单单是写一个工具类型的软件，可以称为“类开发者”,但实际上，在中国，除了大型的软件公司，自己包装一下框架外，有多少这样的类开发者呢？
扯远了……
对于public、protected、private的理解：
public不用说，全局有效的。
private的属性与方法，只能在类定义体里面可以访问。
protected呢？ 相同包内的其他类、所有继承此类的子类可以访问protected的元素。
