Java Data Type - 如何添加持续时间到日期和检查异常

import java.time.Duration;
import java.time.LocalDate;
import java.time.Period;
import java.time.temporal.ChronoUnit;
import java.time.temporal.UnsupportedTemporalTypeException;

public class Main {

  public static void main(String[] args) {
    LocalDate localDate = LocalDate.of(2012, 11, 23);
    System.out.println(localDate.plus(3, ChronoUnit.DAYS)); //2012-11-26

    System.out.println(localDate.plus(Period.ofDays(3)));  //2012-11-26
    try {
        System.out.println(localDate.plus(Duration.ofDays(3)));

        System.out.println(localDate.plus(4, ChronoUnit.FOREVER));
    } catch (UnsupportedTemporalTypeException e) {
        e.printStackTrace();
    }
  }
}
