提问by abdulla-alajmi
I am looking for date and time picker, but found just JCalender that's for date picker and does not support the time
我正在寻找日期和时间选择器，但发现只是用于日期选择器的 JCalender 并且不支持时间
I also found this http://matrex.sourceforge.net/help/DateTimePickerDialog.html
我还发现了这个 http://matrex.sourceforge.net/help/DateTimePickerDialog.html

我喜欢它，因为它简单易用，但我不知道如何获得它或在哪里可以找到它

The LGoodDatePickerlibrary includes a good DateTimePickercomponent. This component allows the user to edit both the date and the time. The time can be edited with optional "spinner" style buttons, with the default "time list" button, or with both.
该LGoodDatePicker库包括了良好的DateTimePicker组件。该组件允许用户编辑日期和时间。可以使用可选的“微调器”样式按钮、默认的“时间列表”按钮或两者来编辑时间。
Fair disclosure: I'm the primary developer.
公平披露：我是主要开发人员。
The DatePicker and the TimePicker classes can also be used individually, if desired.
I've pasted a screenshot of the three components below, (and the demo application).
如果需要，也可以单独使用 DatePicker 和 TimePicker 类。
我粘贴了以下三个组件的屏幕截图（以及演示应用程序）。
The library can be installed into your Java project from the project release page.
该库可以从项目发布页面安装到您的 Java 项目中。
The project home page is on Github at:
