JAVA中的日期和时间选择器 [英] date and time picker in JAVA

问题描述

我正在寻找日期和时间选择器，但发现只有JCalender是日期选择器并且不支持时间

I am looking for date and time picker, but found just JCalender that's for date picker and does not support the time

我还发现这个

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

I like it because it is simple and easy to use, but I have no idea how to get it or where can I find it

推荐答案

检查这个帖子（使用swingx JXDatePicker 组件，他扩展了它的功能）

Check this thread (uses swingx JXDatePicker component, he extends it's functionality)

有没有可用于Java Swing的好的和免费的日期和时间选择器？
