import java.time.DateTimeException;
/**

import java.time.LocalDateTime;

import java.time.ZonedDateTime;

import java.time.format.DateTimeFormatter;


public class Main {


  public static void main(String[] args) {

    try {

      DateTimeFormatter dateFormatter = DateTimeFormatter

          .ofPattern("MMMM dd yyyy");


      LocalDateTime now = LocalDateTime.now();

      String output = now.format(dateFormatter);

      System.out.println(output);


      DateTimeFormatter dateFormatter2 = DateTimeFormatter

          .ofPattern("MM/dd/YY HH:mm:ss");

      String output2 = now.format(dateFormatter2);//时代Java - nowjava.com 提供

      System.out.println(output2);


      DateTimeFormatter dateFormatter3 = DateTimeFormatter

          .ofPattern("hh 'o''clock' a, zzzz");

      ZonedDateTime zdt = ZonedDateTime.now();

      String output
