Java中的哪种数据类型只能保存日期,不需要时间组件？例如,只是为了存储12/07/2012.我正在将数据持久化到具有日期数据类型的数据库中,因此我正在寻找Java中最佳的等效数据类型.
从JDK：
javax.sql.Date：
A thin wrapper around a millisecond value that allows JDBC to identify
this as an SQL DATE value. A milliseconds value represents the number
of milliseconds that have passed since January 1,1970 00:00:00.000 GMT.
To conform with the definition of SQL DATE,the millisecond values
wrapped by a java.sql.Date instance must be ‘normalized’ by setting
the hours,minutes,seconds,and milliseconds to zero in the
particular time zone with which the instance is associated.
或从JodaTime：DateMidnight或LocalDate(谢谢
@cdeszaq)
DateMidnight defines a date where the time component is fixed at
midnight. The class uses a time zone,thus midnight is local unless a
UTC time zone is used.
It is important to emphasise that this class represents the time of midnight on any given day. Note that midnight is defined as 00:00,which is at the very start of a day.
