Java Basics - 执行在哪里?
原标题:Java Basics - Where are the implementations taking place?

例如,一种方法将一个类别清单的物体归来。

public List<Foo> bojangles ()
...

部分法典用Foo Bar.bojangles.iterator();

我对贾瓦来说是新的,但从我能够说的话来看。 清单是一个接口,因此,在其他地方必须采用代号方法。 当挖掘 Java源代码时。 直到此为止,我所看到的正是这句话。 自动取款机本身是背书......在某个地方,我猜测有课堂或抽象课,实际上有这些方法的逻辑:下()和Next()。 但在哪里?

具体类别确实是实际工作。

在Eclipse中,你可以操作debug模式:按步骤操作你的代码,观察可变观。 然后,你可以发现在运行时间究竟发生了什么。

或者,你可以将名单的getClass()印成册,然后核对来源。
