Helper.dateFromYearMonthDate介绍

[英]Answer a Date with the year, month, date. This builds a date avoiding the deprecated, inefficient and concurrency bottleneck date constructors. This implementation is based on the java.sql.Date class, not java.util.Date. The year, month, day are the values calendar uses, i.e. year is from 0, month is 0-11, date is 1-31.
[中]用年、月、日期回答日期。这构建了一个日期构造函数，避免了不推荐使用、效率低下和并发瓶颈的日期构造函数。此实现基于java。sql。日期类，而不是java。util。日期年、月、日是日历使用的值，即年从0开始，月从0到11，日期从1到31。
