如何从 ArrayList 填充 JComboBox? [英] How to populate a JComboBox from an ArrayList?

问题描述

我有一个对象的 ArrayList，所有的对象都有名字.如何使用这些名称填充 JComboBox?我在网上查了一下，到目前为止一无所获.有一些资源，但它们倾向于使用硬编码版本，这是无用的.

I've got an ArrayList of objects, and all the objects have names. How can I populate a JComboBox with those names? I've looked online and found nothing so far. There are some resources, but they tend to go with a hardcoded version, which is useless.

由于我还没有任何代码显示我在做什么，所以我无法附加任何代码.

Since I don't have any code yet showing what I'm doing, I can't attach any.

推荐答案

JComboBox 与 Array 或 Vector 一起使用.您应该使用 ArrayList 中的 .toArray() 方法来创建数组.

JComboBox works with Array or Vector. You should use .toArray() method in the ArrayList to create an array.

String[] names = namesList.toArray(new String[0]);

然后使用名称
