如何将可观察列表转换为数组列表?爪哇

问题描述

我正在尝试在表格视图中获取所有项目，并将它们放置在数组列表中以进行进一步处理.这是我要实现的目标，但是显然行不通.

I'm trying to get all the items in a table view and place them in an array list for further processing. This is what I'm trying to achieve but obviously it won't work.

ArrayList<Consultation> showing = consultationTable.getItems();

推荐答案

很好的建议解决方案:

List<Consultation> showing = provider.getItems();

仅在必要时使用的解决方案:

Solution to use only if necessary:

    List<Consultation> consultations = provider.getItems();
    ArrayList<Consultation> showing;
    if (consultations instanceof ArrayList<?>) {
        showing = (ArrayList<Consultation>) consultations;
    } else {
        showing = new ArrayList<>(consultations);
    }

如果由于某种原因需要使用不在List或ObservableList接口中的ArrayList方法(我不容易想到为什么)，则可以使用后者.

If for some reason you need to use an ArrayList method that is not in the List or ObservableList interface (I cannot readily think of why), you may use the latter.
