Java Data Type - 如何增量日期(时间戳)

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class Main {

  public static void main(String[] args) {
    System.out.println(getDateAsStringIncrementedByYear("04/22/1980 11:30:20",
        "MM/dd/yyyy HH:mm:ss", 1));
  }

  private static String getDateAsStringIncrementedByYear(String inputDateStr,
      String pattern, long yearsToIncrement) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern);
    LocalDateTime dateTime = LocalDateTime.parse(inputDateStr, formatter);
    return dateTime.plusYears(yearsToIncrement).format(formatter);
  }
}
