Java Data Type - 如何以基本ISO日期格式解析和格式化日期

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class Main {
  public static void main(String[] argv) {
    String dayAfterTommorrow = "20140116";
    LocalDate formatted = LocalDate.parse(dayAfterTommorrow, DateTimeFormatter.BASIC_ISO_DATE);
    System.out.printf("Date generated from String %s is %s %n", dayAfterTommorrow, formatted);
    System.out.println("Formatted today = " + DateTimeFormatter.BASIC_ISO_DATE.format(LocalDateTime.now()));

  }
}
