本文整理了Java中org.apache.hadoop.hive.common.type.Date类的一些代码示例，展示了Date类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Date类的具体详情如下：
包路径：org.apache.hadoop.hive.common.type.Date
类名称：Date

Date介绍

[英]This is the internal type for Date. The full qualified input format of Date is "yyyy-MM-dd".
[中]这是日期的内部类型。日期的完整限定输入格式为“yyyy-MM-dd”。
