Java：迭代数组列表 [英] Java: Iterating through an Array List

问题描述

我有一个ArrayList，其中包含我想要执行方法'count'的实例化对象的名称。不过，我不确定是否/如何做到这一点。我有一个循环来扫描数组列表，并添加了伪代码我想要实现的目标。

I have an ArrayList containing names of instantiated objects that I want to execute the method 'count' on. I'm unsure if/how to do that, though. I have a loop to scan through the array list, and added pseudocode with what I'm trying to achieve.

    n = 0;
    while(n <= arrayList.size()){
        (arrayList.get(n)).count();
    }

我是java的新手，我不确定这是可能的，但任何帮助将不胜感激。谢谢。

I'm new to java and am not sure this is possible, but any help would be appreciated. Thanks.

推荐答案

更简单的方法...

ArrayList<MyObject> list = ...
for( MyObject obj : list)
  obj.count()
