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()
