问题描述

当前有一个名为 SundayList 的ArrayList，它会在加载框架 AddStudent (GUI位)后立即加载

Currently have an ArrayList called SundayList which is loaded as soon as the frame AddStudent is loaded (bit of GUI)

Netbeans自动生成的代码是:

The code automatically generated by Netbeans is:

comboboxSunday = new javax.swing.JComboBox();

comboboxSunday.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "Item1", "Item2" }));

如何使用自己的数组加载组合框项目?该数组包含以下项目:

How do I load the combobox items with my own array?The array includes items such as:

Activity1
Activity2
Activity3
Activity4

在我之前的搜索中，人们提到使用toString()和toArray()，并且我对这两种方法都不熟悉，以及它们如何帮助将列表加载到组合框中，因为我是Java的新手. ..

From my previous search, people mentioned about using a toString() and toArray(), and I'm not familiar with either methods, and how they help in loading the list into the combobox as I'm quite new to java..

推荐答案

您可以创建自己的ComboBoxModel，该ComboBoxModel以List作为主要参数，但是要涉及更多

You could create your own ComboBoxModel that takes a List as the main parameter, but that's a little more involved

comboboxSunday.setModel(new DefaultComboBoxModel());
for (Object item : listOfItems) {
    comboboxSunday.addItem(item);
}
