java8、jdk8字符串转化日期，日期转化成字符串

1、新建java类：DateUtils

2、新建方法formatDate

3、实现formatDate方法：public static Lo罕铞泱殳calDate formatDate(String strDate,String pattern) { DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(pattern); return LocalDate.parse(strDate,dateTimeFormatter); }

4、在main方法中测试字符串转化成日期方法：public static void main(String[] args) { System.out.println(formatDate("2017-11-02","yyyy-MM-dd"));}

5、查看测试结果:

6、这个DateUtil衡痕贤伎s类如下：package com.gwolf;import java.time.LocalDate;import j锾攒揉敫ava.time.format.DateTimeFormatter;public class DateUtils { public static void main(String[] args) { System.out.print(parseDate(LocalDate.now(),"yyyy-MM-dd")); } /** * 字符串转化成日期 * @param strDate * @param pattern * @return */ public static LocalDate formatDate(String strDate,String pattern) { DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(pattern); return LocalDate.parse(strDate,dateTimeFormatter); }}
