[Java] java.time 패키지

Java SE 8부터 지원하는 새롭게 재 디자인한 패키지

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.Month;

LocalDateTime timePoint = LocalDateTime.now();

LocalDate ld = LocalDate.of(2022, Month.MAY, 10);
LocalTime lt1 = LocalTime.of(15, 50);
LocalTime lt2 = LocalTime.parse("13:10:30");

System.out.println(timePoint);
System.out.println(ld);
System.out.println(lt1);
System.out.println(lt2);

int second = timePoint.getSecond();

System.out.println(month.getValue() + "/" + day + " " + hour + ":" + minute + ":" + second);
