我可以知道如何将一种日期格式转换为另一种日期格式。

public static LocalDate localDateToAnotherLocalDate(String oldPattern, String newPattern, String input) {
    DateTimeFormatter oldFormat = DateTimeFormatter.ofPattern(oldPattern);
    DateTimeFormatter newFormat = DateTimeFormatter.ofPattern(newPattern);
    LocalDate localDate = LocalDate.parse(input, oldFormat);
    String output = localDate.format(newFormat);
    System.out.println();
    return getLocalDate(output, newPattern);
}

public static LocalDate getLocalDate(String date, String datePattern) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern(datePattern);
    return LocalDate.parse(date, formatter);

}

@Test
void getLocalDateToAnotherLocalDateTest() {
    LocalDate localDate = DateUtil.localDateToAnotherLocalDate("yyyy-MM-dd", "dd-MM-yyyy", "2022-11-20");
    System.out.println("localDate" + localDate.toString());
    assertEquals("20-11-2022", localDate.toString());
}
