篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Java日期时间API系列17-----Jdk8中java.time包中的新的日期时间API类,java日期计算4,2个日期对比,获取相差年月日部分属性和相差总的天时分秒毫秒纳秒等相关的知识,希望对你有一定的参考价值。
通过Java日期时间API系列9-----Jdk8中java.time包中的新的日期时间API类的Period和Duration的区别 ,可以看出java8设计非常好,新增了Period和Duration类,专用于对比2个时间场景:
Period,可以获取2个时间相差的年月日的属性。
Duration,可以获取2个时间相差总的天时分秒毫秒纳秒。
下面应用:
/** * 获取2个日期的相差年月天的年数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenYears(LocalDateTime startInclusive, LocalDateTime endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive"); Objects.requireNonNull(endExclusive, "endExclusive"); return Period.between(DateTimeConverterUtil.toLocalDate(startInclusive), DateTimeConverterUtil.toLocalDate(endExclusive)).getYears(); } /** * 获取2个日期的相差年月天的年数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenYears(Date startInclusive, Date endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive");

} /** * 获取2个日期的相差年月天的月数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenMonths(LocalDateTime startInclusive, LocalDateTime endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive");
