JDK1.8 LocalDateTime 时间类与字符互转

public static void main(String[] args) {

        DateTimeFormatter dateTimeFormatter=DateTimeFormatter.ofPattern("yy-MM-dd");
        LocalDate localDateTime=LocalDate.now();
        localDateTime.format(dateTimeFormatter);
        System.out.println(localDateTime);

        String time="2018-05-18 23:24:25"; //-->"2018-05-18"        DateTimeFormatter dateTimeFormatter2=DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");//严格遵守大小写        LocalDateTime localDate=LocalDateTime.parse(time,dateTimeFormatter2);         LocalDate localDate1=LocalDate.of(localDate.getYear(),localDate.getMonth(),localDate.getDayOfMonth());        System.out.println(localDate1);//2018-05-18

}

　　说明: jdk1.8 严格区分LocalDate(日期)  LocalDateTime(时间日期)  LocalTime(时间)

jdk 1.8 支持新旧(1.8以下版本) date 互转  参考博客:https://www.cnblogs.com/exmyth/p/6425878.html
