I want to implement editing of the combo items, e.g. when I select 3-th item "Item 3" and it appears in the input field, I alter the string to "Item 3 new" and press some button. I want 3-d item to have "Item 3 new" text.
Is there any simple solution?
我想实现组合项目的编辑，例如当我选择第3项“项目3”并且它出现在输入字段中时，我将字符串更改为“项目3新”并按下某个按钮。我希望3-d项目有“Item 3 new”文本。有没有简单的解决方案？

You have to write an ActionListener that replaces the selected element. As a basis, see Using an Editable Combo Box; the full example is in ComboBoxDemo2.
您必须编写一个ActionListener来替换所选元素。作为基础，请参阅使用可编辑的组合框;完整的示例是在ComboBoxDemo2中。
